In this week’s podcast episode, you’ll hear about: King Air flying.Listener feedback from the last episode on “Phantom Cylinder Cracks.”The latest annual inspection I’m involved in.… and a few other things! I’m in the midst of an annual inspection on a Piper Comanche.  I might talk more about this one in a future episode, but for now,  I mentioned two strange things about this airplane in this week’s podcast: The first strange thing was the oil quick drain kept seeping after I drained the oil and closed the drain valve. I was perplexed when oil was collecting on the bottom cowling and seeping down over the nose tire. Finally, I had to cut the safety wire and remove the Saf-Air P5000 drain valve to take a look. Here’s what I found:  I removed the drain valve and put a temporary plug in the oil sump to prevent any further seepage.  If you look closely, you can see a portion of the black o-ring holding the valve slightly open. Here’s a closer view:  After opening the valve, I noticed the top o-ring had been pushed up off the valve, and it was the second o-ring that was holding the valve open.  (Don’t worry, the other o-ring fell out of the hole when I removed the valve, so it’s not stuck somewhere in the oil sump.)  We will install new O-rings on the valve before reinstalling it in the oil sump.  It actually has 3 total o-rings… the top 2 keep the oil from draining out of the sump, and the lower o-ring (that you can’t see in the photo) is slightly larger and it keeps oil from seeping out around the drain nipple during the oil draining process.  McFarlane sells a kit that includes the three new o-rings and a new snap ring. You can listen to the audio to hear more about this story. … and hopefully, in a future episode, I’ll be able to update you on the weird electrical problem on this same airplane.

231 – Piper Comanche Weird Electrical Problem and Seeping Oil Drain Valve

Do you think these really are cracks between the spark plug bosses and the fuel injector bosses?  (Cirrus SR22 Continental engine.)     The owner of a Cirrus SR22 was told by a service center he had 4 cracked cylinders on his engine. However, after taking a closer look and bringing their most experienced technicians together to thoroughly clean and examine the cylinders, it was discovered they were not cracked after all. The service center was very professional with their communications and the process they used to evaluate the cylinders. This whole scenario was such a great example of healthy collaboration between an aircraft maintenance service center and an airplane owner. Listen to the audio of this week’s podcast to hear the full story, and some email communications I had with the airplane owner. After thinking about the situation, here are some thoughts: If an airplane engine cylinder is truly cracked, it needs immediate attention.Sometimes, what appears to be a crack, is not a crack after all.Thorough cleaning and precise evaluation are required.Sometimes a second and third expert opinion are helpful.Excellent communication between airplane owners and service centers is key. Have a great week everyone! The post, 230 “Phantom Cracks” in Airplane Engine Cylinders appeared first at AirplaneOwnerMaintenance.com

230 “Phantom Cracks” in Airplane Engine Cylinders

The charging system was not working, but why? There was normal voltage at the alternator field terminal. The field circuit resistance seemed normal as well. But the alternator was not producing the normal 28 volts during operation.   Occasionally, it would produce a small amount of output voltage, like 25 or 26 volts, and then drop back down to battery voltage. Clearly there was a problem. After troubleshooting and seeking advice from a Cessna service center, we replaced the battery contactor and the alternator contactor in the MCU (master control unit) on the firewall.  (The MCU is the electrical control box for the airplane.  It’s located on the forward left side of the firewall.) Replacing the contactors did not fix the problem. After more troubleshooting and some calls to Hartzell Engine Technologies to speak with two different people, and after talking things over with the owner, we decided to order an overhauled alternator and a new ACU (alternator control unit.) They arrived the next day, I installed them, and the system worked perfectly. The alternator was back to producing its normal 28 volts.  (I just wish I had taken the old alternator apart to see if I could determine the problem… I’m guessing one or both of the brushes were severely worn.) The following photo shows what’s inside the MCU.  The alternator contactor is the one in the top of the photo, slightly left of center.  And the alternator control unit the the device to the left of the contactor that says “Lamar” on the side. When replacing anything in this box, it’s very helpful to take photos first in order to put everything back in its place during reassembly!  Listen to the audio podcast for this episode to get the full story. This episode also includes some of the email responses I received after asking if listeners wanted to continue receiving stories about exhaust valves.  Thank you to all who responded! In a nutshell, everyone wanted to continue hearing about exhaust valves and the stories about lapping them and saving them, especially the stories that are instructive and educational. Have a great week everyone! The post, “229 – Cessna 206 Alternator Not Working” appeared first at AirplaneOwnerMaintenance.com

229 – Cessna 206 Alternator Not Working

Dan and Jeanne are some of the nicest people you will ever meet, so it’s always a privilege to work on their airplane.  It was annual inspection time, and the compression test on cylinder #1 was 25/80.  The borescope showed a corresponding reason for the low compression… the exhaust valve had an uneven appearance, indicating it was not sealing well against the valve seat, and there was air leakage around the edge, causing that edge to get extra hot and burn… this is the reason for the uneven color pattern at 10 to 11 o’clock in the photo:  I discussed the situation with Dan, and we decided it was worth a try to lap the valve in place without removing the cylinder, in hopes we could save the cylinder from premature removal. I lapped the valve and installed a new rotocoil to help ensure the valve was rotating properly during operation. After reassembling everything and running the engine, we got a fantastic result… the compression was now 75/80! When the annual inspection was completed, I sent the airplane out the door with great confidence the engine would perform well… and it did. Not long after that, Dan and Jeanne flew the Bonanza to Montana to visit family and then later made the journey back home. At the time of the annul inspection, Dan had agreed it would be a good idea to inspect the #1 exhaust valve at the next oil change to make sure all was well. After having flown about 37 hours since the annual and since lapping the #1 exhaust valve, Dan returned to have things checked out. The oil and filter change were completely normal; the compression in cylinder #1 was 77/80; and the borescope revealed the #1 exhaust valve had returned to normal!   Check it out: the circular patterns on the valve are now nice and concentric.  I’m hopeful Dan will get many more hours of reliable service out of this cylinder since we stopped the harmful trajectory of a burning exhaust valve. On another note, I discussed a couple things in this episode that I noticed this past week while flying. One was related to NOTAMs and the importance of being aware of them (along with something I discovered about NOTAMS, approach plates, and ForeFlight.)The other one was a tip about starting PT-6 engines when they are still hot after a quick stop to drop off passengers and refuel. In my research, I discovered an online course about NOTAMs, and I wanted to pass this link along for anyone who might be interested: notamsmadeeasy.com This is a course by Sarah Fritts.  I do not know Sarah, and I do not receive any compensation from this course, but it seems like a good training resource, and I like to help promote those when I see them.

228 – Saving a Cylinder on Dan & Jeanne’s Bonanza

This Bonanza had a problem in the landing light wiring circuit.  All kinds of weird things were happening when the light was turned on in flight.  You can listen to the podcast audio for more details on this squawk. I removed the induction filter cover and the landing light assembly and inspected the wiring.  It turned out the landing light power and ground wires were chafing against each other… probably over a very long period of time.  Take a look at the area of concern in the red circle on the following photo:  At first glance, it wasn’t visually obvious there was a problem.  But after separating the power and ground wires, it became very clear what was happening.  As the internal strands of the power and ground wires began to just barely make contact with each other, the short-to-ground situation started wreaking havoc in the electrical system.  The following photo shows the areas where the insulation was worn all the way through to the internal wire:  Sometimes there was static over the comm radio, sometimes the TCAS and intercom would cycle power off and back on, and sometimes the landing light circuit breaker switch would flip off. I repaired the wiring and secured it really well with ty-wraps and silicone to prevent further chafing.  Now Brad will be able to use his landing light any time he wants and be confident it will perform normally. Vibration from piston engines can create some bad situations!  It’s always a good idea to take an extra minute or two to look around the engine compartment whenever you’re in there, like at the oil change, or some other maintenance event, like cleaning spark plugs. Another interesting squawk on this same Bonanza was a burning exhaust valve and corresponding low compression.  The borescope revealed the classic appearance when the valve is not sealing well against the valve seat.  Take a look:  I had lapped this valve at the last annual inspection and installed a new rotocoil to help ensure it would rotate properly, so when it still showed an appearance of a burning valve a year later, I figured we would likely need to remove the cylinder and send it for repair. However, the Bonanza owner uses Savvy Aviation to manage his maintenance on the airplane, and the borescoping experts at Savvy thought it would be worth lapping the valve again to see if it could be saved. I was happy to give it a second try.  I lapped the valve heavily this time and finally, I was satisfied.  I installed a new rotocoil again, and after running the engine, I rechecked the compression, and was super happy to see that it was 74/80! I feel 90% confident that when the next annual inspection rolls around, this valve will have returned to a normal appearance.  I’ll be curious to see how it turns out. All in all, it was a good annual inspection, and Brad should be good to go for another year of flying!

227 – Electrical Chaos When the Landing Light was Turned On

It was a beautiful Tuesday morning at KSHD, and we had the maintenance hangar door open with a good view of the runway.   A nice, red and white Piper Lance made a perfect landing on runway 5.  As the airplane taxied up to the ramp, I thought, “It would be nice to meet that guy, whoever he is.” Momentarily, he was standing in our shop, asking if we could help with an electrical issue.  It turned out Merle was a super nice gentleman, and he had flown in with his brother, Dave, and their colleague Ron.  They were on their way to Pennsylvania that morning, but made a precautionary landing at Shenandoah Valley because of the electrical failure. I was eager to help.  I grabbed my multimeter and hopped in the airplane.  When I tried to start the engine, all I got was a small and very feeble attempt to turn the engine and prop.  The battery was too weak to run the engine. I remove the cowling and got access to the alternator.  After removing the field wire from the field terminal on the alternator, I turned the master and alternator switches on and verified there was battery voltage at the field wire.  I was then satisfied the voltage regulator was working fine, and the problem was likely in the alternator or the wiring circuit. I then measured the resistance between the alternator field terminal and ground, and at first I got a resistance reading, but when I moved the prop a bit, I had no continuity.  There should be a resistance reading, maybe around 6 ohms, give or take a little, for a 12 volt alternator.  At this point, I was 90% sure the alternator was bad. We started searching, and found a local parts supplier had an overhauled alternator, and also one that was “as removed.”  Merle opted for the overhauled one, and one of our guys made the short drive to pick it up.  Unfortunately, that alternator had a crack in the bolt hole for attaching the alternator belt tension arm. We ended up overnighting another overhauled alternator in, and got them going the next day.  It was great meeting these guys!  Merle, Ron, and Dave… if you’re ever passing through again, stop in and say hi, and maybe we can go grab a burger at the Old School Burger bus down at the Valley Pike Farm Market. On a totally different subject, I also talked in this podcast episode about an Aerostar trip we made to Wisconsin this week… not much of an FBO at this little airport near Lake Geneva, WI.  Be sure to listen to the episode to find out about an interesting phenomenon I learned about on the return trip… a momentary harmonic vibration in the clouds. That’s all for this episode!

226 – Piper Lance Lands at SHD After In-Flight Electrical Failure

And the winner is… Ben Moroze! Recently, in podcast episode #223, I asked for help in identifying an ATC intersection we flew over on our way into Dulles Airport, (KIAD) awhile back. I remembered it sounded something like “you-dee-ah” or something similar. Maybe something like “UDIYA” except that’s not it. Well, Ben emailed me after listening to episode 223, and he correctly identified the intersection as “UDIYU” and told me it’s on the DOCCS THREE arrival and also on the GIBBZ FOUR arrival. Thank you Ben!  You’re the first one to respond after listening to episode 223. Then, I sent an email out yesterday morning and received a good handful more responses about the intersection, UDIYU. A big thank you to all of you who responded to this email! You can listen to the audio podcast for this episode to hear about all those responses. I also received a couple photos from my good friend Clark, showing the position of the UDIYU intersection… here’s one of those:  Thanks Clark, for the photos! And here are a couple of my screen shots to get more context for the arrivals with the UDIYU intersection:   And thank you to ALL OF YOU GUYS who responded to my question… it’s really fun to learn about these obscure situations with you. Now… I’m off to the shop to work on a Bonanza… and be sure to tune in again in a future episode to hear what I found in this Bonanza’s landing light wiring circuit that was causing all kinds of strange and weird effects in other systems as well.

Thank you Ben! You’re the first one to respond after listening to episode 223. Then, I sent an email out yesterday morning and received a good handful more responses about the intersection, UDIYU. A big thank you to all of you who responded to this email! You can listen to the audio podcast for this episode to hear about all those responses. I also received a couple photos from my good friend Clark, showing the position of the UDIYU intersection… here’s one of those: <a href="https://airplaneownermaintenance.com/wp-content/uploads/2023/06/Attach0.jpg" rel="nofollow" target="_blank"></a> Thanks Clark, for the photos! And here are a couple of my screen shots to get more context for the arrivals with the UDIYU intersection: <a href="https://airplaneownermaintenance.com/wp-content/uploads/2023/06/IMG-0060-1.png" rel="nofollow" target="_blank"></a> <a href="https://airplaneownermaintenance.com/wp-content/uploads/2023/06/IMG-0063-1.png" rel="nofollow" target="_blank"></a> And thank you to ALL OF YOU GUYS who responded to my question… it’s really fun to learn about these obscure situations with you. Now… I’m off to the shop to work on a Bonanza… and be sure to tune in again in a future episode to hear what I found in this Bonanza’s landing light wiring circuit that was causing all kinds of strange and weird effects in other systems as well. Have a fantastic weekend!

225 – Obscure ATC Intersection Mystery Solved (It’s UDIYU!)

Recently, I received an email from Jim Janaitus, owner of a Cessna 182.  He told me the story of lapping an exhaust valve on his engine because the valve showed signs of burning even though the compression was still in the high 60’s.  Take a look at the appearance of the valve before lapping:  The area from about 12:00 to about 3:00 is the bad area, indicating the valve is not seating well in that area. Jim lapped the valve and installed a new rotator.  I was super happy when he said, “It went better than I imagined.” Here’s a follow up photo of the same valve about 12 flight hours later:  Isn’t the improvement remarkable?! It’s not perfect, but it’s MUCH BETTER than before, and Jim has an excellent plan to monitor the condition of this valve every 20 hours or so. Well done Jim! Be sure to listen to the audio for this week’s podcast to hear this story, along with some other weird electrical issues I’ve been sorting out on a Bonanza and on a Cessna 210. Have a great week!

224 – Jim’s Exhaust Valve Rescue on his Cessna 182 Engine

Piper Cherokee

In the beginning of this week’s podcast episode, I want to give a big congratulations to my friend, Chris Wieczorek, who recently got his A&amp;P certificate!  Listen to the audio to find out how Chris pursued getting his A&amp;P in the midst of being a full time attorney and engineer with a wife and 4 kids! Chris, you are an inspiration!  Well done! This week I also had the opportunity to take care of a couple issues on my friend, Dave Ovad’s Bonanza… you can hear more about these items as well in the podcast: We turned up his full power fuel flow a bit to bring the CHT’s down.We installed a couple very specific washers in his nose gear retraction linkage at the idler arm connection. The washer part number is 100951CR016YF. It’s always good to see Dave! Now for the Piper Cherokee… this is the one I’m completing an annual inspection on, along with some squawk repairs.    Here’s a list of some items on the Cherokee we discuss in this podcast episode: Resealing and lubing the fuel selector valve.Installing a new flash tube in the tail strobe light.Replacing the old style throttle and mixture control rod ends with the new rod end bearing style rod ends.Replacing one cowling pin bushing (part number 69790-000.)Installing a new 28L battery in the ELT remote switch in the instrument panel. The final two items we talk about in this episode are two different electrical issues on two different airplanes. The first one is an A36 Bonanza, and the new alternator has been dropping off line.  (The alternator was replaced again and then the voltage regulator, at another airport, and that did not fix the problem.) Through Beechtalk, we discovered a fix for this issue has been developed, where you install a special part number capacitor between the F1 and F2 terminals on the alternator, thus dampening out the voltage spikes that sometimes happen during the break-in phase of a new alternator. Hopefully this will solve the problem! The second electrical problem is on a Cessna 210, and it’s one of those weird and frustrating situations that’s hard to figure out.  It does fine on the ground, and then in the air, the alternator output circuit breaker is popping intermittently.  (Although I need to verify this directly with the owner.) Hopefully we can solve this one soon as well. The final phase of this podcast episode is about a couple recent flights in a King Air 200.  One of these was to Dulles (KIAD) and how we were routed onto the approach.  We usually fly KSHD direct to CSN (Cassanova VOR) and then direct to IAD. This time, we would be landing on 19C, and we were cleared “After CSN, turn left direct to” (and here’s where I can’t remember the name of the intersection, and it’s driving me crazy!)  It was something that sounded like “you-dee-ah” or something like that.  Maybe something like “UDIYA” except that’s not it. If you know what this fix or intersection is called, please let me know… thanks! Thanks for listening to the podcast, and have a great week!

223 – Piper Cherokee Annual and Other Maintenance Adventures

I inspected another A36 Bonanza recently, and one of the cylinder compressions was too low… lower than the minimum prescribed by Continental using the master orifice tool. I had two options: Option One:  Remove the cylinder for repair or replacement. Option Two:  Make the exhaust valve seal better and improve the compression result in hopes of saving the cylinder from premature amputation. I chose Option Two. It was at least worth a try… … and the result was stunning! After lapping the valve in place and installing a new rotocoil, I ran the engine again and rechecked the compression. It was 75/80! The lowest cylinder on the engine was now the highest cylinder. I also lapped the exhaust valve in cylinder #2, and that one improved from 49/80 to 63/80. If you’d like more info about valve lapping, click here for episode 109. Another surprise during the inspection was a cracked / leaking exhaust riser.    Here’s a close-up view of the bad area:  Also in this episode, I talked about some other squawks that were repaired during the inspection.  Be sure to listen to the audio for all the details. In Part Two of this episode, I talked about our most recent trip in the King Air.  It was quite an adventure navigating some weather situations!

222 – How an Engine Cylinder Went From 25/80 to 75/80!

A podcast devoted to airplane owners and the maintenance of their airplanes.

Maui is simply amazing!   Maria and I thoroughly enjoyed our trip, and here are some highlights.  (And for the aviation maintenance portion of the trip, see the last episode, 220.) So many indescribably beautiful beaches to see:  Maria and her new friend, Firmiana, at the Upcountry Farmers Market… the most amazing farmer’s market I’ve ever seen!  Maria was right at home with all the fresh fruits and vegetables.  A ridiculously delicious dessert at Kimo’s in Lahaina… Hula Pie.  Chocolate cookie thin crust, Macadamia nut ice cream, hot fudge, mac nut pieces, and whipped cream!  Gus’ Shave Ice!  It’s the best shave ice on Maui… made with frozen fruit.  Our new friends, Melissa and JT, who we met in line at “The Cinnamon Roll Place” in Kihei.  A super amazing air tour with Leslie and Erica.   A favorite stop on The Road to Hana, Aunty Sandy’s Banana Bread.  Waianapanapa State Park, home of the famous “Black Sand Beach.”  Crazy-good pizza and salad at Hana Farms.   Haleakala, the famous 10,000 foot volcano and crater.   Driving back down the mountain… watching for cows along the road and continuous switch-back turns.  After a most amazing two weeks, it was time to leave our little ohana, our home-away-from-home.  …and after all the wonderful-ness, it was time to say goodbye to John and Leslie and return to the mainland.  Thank you John and Leslie for such a super-awesome time on Maui! If you ever make a trip to Maui, be sure to check out John and Leslie’s websites… the information they provide is a game-changer for  planning a Maui adventure: The Aloha 360 Podcast with John and Leslie Caubble.  These episodes have tons of must-have information for a trip to Maui. The Road to Hana Audio Guide.  Learn about the best stops along the Road to Hana, some of which you would drive right past without a guide like this.  (Be sure NOT to miss “Aunty Sandy’s Banana Bread” on the Keanae peninsula!) The Fly Maui Flight School at Kahalui Airport (OGG.)  A scenic tour from the air is an absolutely incredible perspective! The Ultimate Air Maui indoor trampoline park.  This is a local favorite for kids’ birthday parties.

221 – Maui Adventures in the Air and on the Ground!

We arrived on Maui the evening of March 27 and were greeted by our friends, John and Leslie Caubble, with a “lei greeting” which is a warm welcome with a beautiful ring of fresh flowers around your neck. We were there to do several things: Connect with our friends, the Caubbles.Work on the flight school airplanes.Enjoy a wonderful vacation.See amazing sights and taste amazing food! The trip was truly epic. In this episode, I focused mainly on the airplane side of things. In the next episode, I’ll talk about the incredible airplane ride Leslie took us on, and also some of the other adventures we enjoyed. So here we go… the morning after we arrived, Leslie gave me a tour of the airport and turned me loose to begin a 100 hour inspection on one of the flight school Cessna 172’s. I unpacked my tools and supplies and “set up shop” in the T-hangar.  The first few days, I was overwhelmed and I was having a blast, all at the same time! Getting used to a new situation, inspecting the airplane, and fixing the things that needed fixing were all worthwhile challenges, and I’m super thankful for the opportunity. And, it turned out that all three of the school’s airplanes came due for 100 hour inspection within about the same week.  I did one of the inspections, and helped with the other two.   What an adventure! Occasionally, I’d take some time to go enjoy a local beach with my wife Maria before going to the airport… there are so many great beaches to choose from!  We packed so much into our short 2 weeks on Maui, and I’ll share some of those adventures in the next episode. The day before we left was Easter Sunday, and we were so blessed by the 7 am service with John and Leslie at Hope Chapel in Kihei.  Mahalo Nui Loa (thank you very much) to John and Leslie for an absolutely amazing time on Maui! … and more to come in the next episode! P.S. If you ever get the opportunity to visit Maui, it’s totally worth it!  I highly recommend the following resources that will make your trip so much better: The Aloha 360 Podcast with John and Leslie Caubble.

220 – An Epic Working Vacation to Maui!

It took some significant detective work and deciphering to solve this mystery. The brake caliper at the top of the photo was the wrong part number for the A36 Bonanza I was working on. The one at the bottom of the photo is a serviceable one we found on eBay.  It was the correct one, and the 1/8 inch extra depth at the edges of the caliper made all the difference. This problem apparently went unnoticed for an undetermined amount of time. The only reason I discovered the problem was because I installed new brake linings and after reassembling the brake caliper, the wheel would not turn at all.  Everything seemed to be working fine with the worn linings.  But new linings made it too tight for the wheel to turn. After installing the correct brake caliper, everything was back to normal. What an ordeal!  I’m glad it’s fixed. In this week’s podcast episode, I talked about the brake situation above, and about some flying from this week. Here’s a sampling of the places I had the opportunity to fly to this past week: Near Myrtle Beach SC.PennsylvaniaNew YorkMontpelier VTChattanooga TNDalton GA And just for fun, here’s a photo of the King Air on the ramp in Vermont… we put the engine and pitot covers on for the night while we were there.  Thanks for checking out the podcast!  The next episode might just come from Maui!  We’ll see.

Not long ago, there was an oil leak on the right engine of a Cessna 414.  The leak was significant enough to come out the louvers on the top cowling in flight.  There was oil all over the rear inboard area of the engine, so the big question was, “Where is the oil leak coming from,” or “Where is the source?”  With so many possibilities, it was difficult to find the leak. After multiple cleanings and ground runs, it was becoming more clear. It was still however, hard to be certain.  It seemed to be coming from the inboard forward base of the oil cooler.  A flashlight and small mirror were somewhat helpful to see the area:  The borescope was also helpful to take a closer look:   Finally, after making the best evaluation I could without disassembling anything, I told the owner I was fairly certain the oil cooler was leaking… it seemed there might be a small crack in the oil cooler. The annual inspection was already scheduled for this airplane, so it made a good time to verify the oil leak.  The owner is an A&amp;P, and he removed the oil cooler himself.  I was hoping I had not steered him down the wrong path on this one! He discovered it’s not an easy task to remove the oil cooler from his engine, but he persisted and got it done. He sent me a text message and told me he had removed the oil cooler and when they first looked at it, he was not sure it was cracked.  But after pressurizing it with 5 pounds of air pressure, the leak was obvious. About the oil cooler, he told me “I tell you it was a job getting that off.”   The black circled area is where the crack was:   And here’s the really fun part… watch this video to see the bubbles confirming the source of the oil leak: Here’s the engine after the oil cooler was removed… definitely “major surgery!”  This was the main maintenance topic in this week’s podcast, and we also talked about these items as well: Aerostar voltage regulator adjustment.Alternator charging system troubleshooting.Our upcoming trip to Maui! Thanks for listening, and we’ll see you in the next episode! The post “218 – Engine Oil was Seeping Out of the Top Cowling” appeared first at AirplaneOwnerMaintenance.com

218 – Engine Oil was Seeping Out of the Top Cowling

I recently removed a magneto from a Piper Cherokee, and my curiosity about why the magneto had failed got the best of me.  I took the mag home, sat down at the kitchen table, put my grandson Spencer on my lap, and took the magneto apart!  It was great fun having him help me   Before long, we had the case apart, and it quickly became obvious why the magneto wasn’t working… there were 6 broken teeth on the distributor gear!  And 3 of the broken teeth were together in a row, making it impossible for the distributor gear to mesh with the drive gear… this mag was completely dead.  It had been more than 600 hours since the last 500 hour magneto inspection. I wonder how long it had been since the first tooth broke… we’ll never know. But it does remind me of the importance of doing 500 hour magneto inspections.  For Part 91 airplanes, it’s a recommendation and not a requirement, but in this case, I think the recommendation is a really good one.   You can listen to the podcast episode for more details about the troubleshooting process on the magneto, and here are some other items also included in this episode: Some King Air flying this week (I never get tired of the “view from the office!”)  Our complex ATC clearances we received on the way to the Boston area.The annual inspection I’m currently doing on an A36 Bonanza… here’s the overhauled alternator drive coupling I installed because the old one failed the slippage torqe test:  Our IA renewal seminar at Blue Ridge Community College… it’s always a good time to see friends, learn some things, and satisfy the FAA requirements to keep my IA certificate current.And finally, Maria and I are getting very excited about our trip to Hawaii!  We’re going to visit John and Leslie Caubble on Maui, and I’ll be working with them on the flight school airplanes at FlyMauiHI.com  It’s going to be a grand adventure!

217 – Does Your Magneto Have Any Broken Teeth?

Here’s the short answer:   Worn and contaminated brushes inside the alternator.   Check it out:  My theory is that the excessive amount of carbon dust from brush wear was causing a short circuit situation between the brushes, and not allowing the field circuit in the alternator rotor to be properly energized for normal operation. Here’s a comparison of the old and new brushes:  This story comes from a recent situation on the right engine of this Aerostar aircraft:  Since the alternator has externally removable brushes, it turned out to be a minimally invasive surgery to fix the problem.  I cleaned the brush holder and also the slip rings inside the alternator, and after installing new brushes and reassembling everything, the alternator performed flawlessly. Listen to the audio to hear the full story. This episode also covers some of the email responses I received last week from some listeners, and here’s one of the highlights: Glen sent me a photo of he and his dad in front of his Piper Cherokee… I love to see  different generations enjoying aviation adventures together!  One more fun fact:  Glen’s mom took her private pilot check ride years ago with Glen in the back seat of their Cessna 175 when he was 3 weeks old!  What a great story! Thanks Glen, for sharing some of your story with us! This episode also covers a recent trip to Charlotte in another Aerostar, and the interesting routing we got from ATC on the way there… definitely some great IFR and ATC lessons to observe and learn from this one! The Charlotte trip also sparked some conversation about twin engine charging systems, and paralleling issues that can happen… this situation is still in process, and I’ll try to give an update sometime in the future. Finally, I had the privilege of joining Carl Valeri, Tom Frick, and Bill English on episode 301 “What is Your Most Challenging Approach” of the Stuck Mic AvCast.  It was great fun talking about challenging approaches, both instrument and visual approaches. Here’s a link where you can listen: SMAC301 What Is Your Most Challenging Approach?

216 – WHY is the alternator not working?!

Clark and his family came to Virginia to visit his mom recently, and on the way up from Florida, the right vacuum pump quit working… as often happens when a vacuum pump quits, the drive shaft had sheared off, saving the engine from catastrophic damage. In times like these, a good question to ask is, “What does this make possible?” In this case, it made it possible to tackle a maintenance project with a good friend! You can listen to the audio in this week’s podcast to hear about how I got to know Clark, and how he became the kind of friend I would want to go the extra mile for, whenever I can. We changed the broken vacuum pump, installed new filters, and got him all set for the trip back home.  (Ask him if he got to fly much on the trip… the answer would be no, because his wife is learning to fly and she took over the controls for most of the trip   It’s always fun when you can get an airline captain turning wrenches!  Clark is very mechanically inclined, and I think the whole experience put a big smile on his face.  Another highlight recently on a Saturday morning was when I took my mom for an airplane ride… she’s 86 years old and still very happy to get in a little airplane and go flying!  We had a great time flying around the beautiful Shenandoah Valley.  You’ll hear about this story in this episode as well.  And finally, my wife Maria and I have an exciting trip planned in just over a month from now… we’re going to Hawaii for the first time!  Our friends, John and Leslie Caubble, operate a flight school on Maui, so we’re going to visit them and I get to help work on the flight school airplanes… we’re super excited about this adventure! You can learn A LOT more about John and Leslie through their two podcasts, The Aloha 360, and Fly Maui.  They are simply GREAT people! https://www.flymauihi.com/blog https://www.thealoha360.com/podcast The post, “215 – Vacuum Pump Adventure with Clark, my Airline Captain Friend” appeared first at AirplaneOwnerMaintenance.com

215 – Vacuum Pump Adventure with Clark, my Airline Captain Friend

This is a good looking exhaust valve with a nice concentric appearance.  However, the compression was very low at 8/80.   I lapped the valve, hoping it would improve the compression test result… it only came up to 10/80, and that was after running the engine again and getting it nice and hot. Although the valve face showed a healthy appearance, the seating area was telling a different story.  Check out the following borescope photo of the seating area showing a possible leaking area:  It appeared there was abnormal wear on the valve seat, and the valve was not able to seal well, causing an unacceptably low compression result. Listen to the audio for more details on this one. I asked the question, “Borescope or compression tester… which one is better?” Let me know what you think after listening.  I’m curious to hear your thoughts. Just click the button over to the right and record a brief audio message for me. Thanks! We ended up sending cylinder #5 out for repair, and then reinstalling it. We did a test flight today, and everything went very well… ready to go for another year!  Here are some links to information on cylinder / engine break-in procedures: Lycoming SI1427C Proper Engine Break-In Engine Break-In: It’s Easier Than You Think Savvy Aviation / EAA webinar slides by Mike Busch (Cylinder Break-In.)

214 – An Unacceptably Low Cylinder Compression

Where are you RIGHT NOW in your aviation journey?Have you started flight training, but stalled out along the way?Did you finish that instrument rating?How about the commercial certificate, or CFI, or even CFII?Ever dream about getting your A&amp;P?Have you wanted to be an airline pilot for years and years?Did you give up along the way when you ran out of money?Maybe you want to be a fighter pilot.Maybe you want to ferry airplanes around the world.Or some other crazy, wonderful dream!If you resonate with any of the above, you just might be an excellent candidate for aviation career coaching with Carl Valeri.Last year in 2022, when I was feeling grumpy and restless in my full time A&amp;P/IA job (and longing to fly more,) I signed up for a career coaching session with Carl Valeri.  It was one of the best decisions I made in that time of transition.Now, I have a pilot position flying for a local company in their King Air 350, and I work part time in my previous A&amp;P job, and I’m loving it so much more!As I’ve shared about my work transition, I’ve heard from a fair number of people who have also thought about pursuing a flying job, or getting their A&amp;P, etc.My encouragement it this:  If it’s in your heart to do it, and you can’t stop thinking about it, then go for it!I know there are all kinds of obstacles to get past like fear, doubt, money, nay-sayers, etc.But you don’t want to look back years from now and regret not going for it and at least trying to reach your dream.If you’re in this place of decision, and you’re not sure what to do, I highly recommend contacting Carl Valeri, and signing up for an hour of his coaching.Carl is uniquely suited to give wise counsel to people pursuing an aviation career.He’s an airline captain and airline training instructor, aviation podcaster, and aviation career coach, with such a wide variety of experience in aviation.  He certainly has his finger on the pulse of aviation at this current time.Carl helped me sort through my ideas, put me in touch with some key people for me to talk with, and gave excellent recommendations for how I could move forward.I’m super grateful for his wise counsel.How about you? Could you benefit from talking with Carl about your aviation dreams?If yes, then sign up here: (Be aware, you may need to sign up weeks in advance since Carl’s schedule fills up quickly.)https://valeri-aviation.thinkific.com/courses/career-coachingIn my opinion, Carl Valeri is one of the best aviation career coaches in the world… he really helped me last year when I paid for an hour of his coaching. It’s a super valuable resource, and I highly recommend him… it is money very well spent if you are trying to decide the best way to reach your aviation career goals.If you want to get to know Carl before you sign up for coaching, the best way to do that is by listening to both of his podcasts:Aviaton Careers Podcast Stuck Mic Avcast You can also check out his YouTube channel, and watch the videos there.Toward the end of last year (2022) I sent Carl an audio message to update him on my new flying job and to thank him for his excellent counsel.He included my message in a recent podcast episode that is also on YouTube.  I had no idea he had included so many special effects in the video.If  you haven’t already watched the video, scroll back to the top and watch it.Thank you Carl Valeri, for all you do to encourage us and help us reach our  aviation goals and dreams!  We appreciate you!I have one more friend I want to thank in this episode… Donnie Simmons.Something was driving me crazy in the King Air when I would hook up the GPU to the airplane and work with the avionics in the hangar.There was constant static in the copilot side headset, and I could not get it turned off… it was driving me nuts!Finally the other day, Donnie sat in the airplane with me and I showed him what I’d been noticing.He helped me with multiple things, but here’s the one that really surprised me:Donnie suggested that perhaps the LED hangar lights were breaking the squelch in the radio, and that is why there was constant static.So I walked over to the circuit breaker panel and turned off the 4 hangar light breakers, and sure enough, NO MORE STATIC!Thank you Donnie!Another valuable lesson learned, and I’ll know for next time.The post “213 – Stellar Advice for YOUR Aviation Career” appeared first at AirplaneOwnerMaintenance.com

I had no idea he had included so many special effects in the video.If you haven’t already watched the video, scroll back to the top and watch it.Thank you Carl Valeri, for all you do to encourage us and help us reach our aviation goals and dreams! We appreciate you!I have one more friend I want to thank in this episode… Donnie Simmons.Something was driving me crazy in the King Air when I would hook up the GPU to the airplane and work with the avionics in the hangar.There was constant static in the copilot side headset, and I could not get it turned off… it was driving me nuts!Finally the other day, Donnie sat in the airplane with me and I showed him what I’d been noticing.He helped me with multiple things, but here’s the one that really surprised me:Donnie suggested that perhaps the LED hangar lights were breaking the squelch in the radio, and that is why there was constant static.So I walked over to the circuit breaker panel and turned off the 4 hangar light breakers, and sure enough, NO MORE STATIC!Thank you Donnie!Another valuable lesson learned, and I’ll know for next time.The post “213 – Stellar Advice for YOUR Aviation Career” appeared first at <a href="http://www.airplaneownermaintenance.com/213" rel="noreferrer noopener nofollow" target="_blank">AirplaneOwnerMaintenance.com</a>

128 – Should I Buy a Twin Cessna or a Beech Baron?

During the recent annual inspection on Drew Wright’s Cessna 182, cylinder #1 had a low compression of 42/80.  However, with the amazing technology of borescoping, he was able to take a look inside the cylinder.  The nice concentric circle of deposits on the face of the exhaust valve indicates a healthy valve.  Drew wondered if perhaps this valve would be a good candidate for lapping in place, without removing the cylinder.Even though the valve appeared healthy, Drew noticed a significant amount of air leaking out the exhaust during the compression test.  Once again, his borescope was very helpful in observing the condition of the exhaust valve and seat area.  The valve looks good, except for the rough and uneven seating area.  The seat also looks good, except for the corresponding rough and uneven seating area.With the supervision of his A&amp;P, Drew was able to remove the rocker cover and the exhaust valve springs.  After verifying the valve guide was in good condition with no excessive wear, and the valve was sliding freely in the valve guide, he was ready to “lap” the valve (to apply a small amount of valve grinding compound to the edge of the valve using a long Q-tip through the top spark plug hole, and spinning the valve against the seat to smooth out and improve the seating area.)Drew used a piece of wood dowel rod, some clear tubing, and some hose clamps, for this task… I like his idea so much, I’m planning to use this technique in the future.One of the most important parts of the lapping process, is cleaning out the residue after the job is finished.  One method is to spray Av-gas into the top spark plug hole to wash the grinding compound off the valve and the surrounding areas, and let it run out the bottom spark plug hole.  Multiple washings, along with some compressed air, cleans up the area very well.  An additional thing Drew did was to push a thin cloth into the top spark plug hole, and pull the valve back to squeeze the cloth between the valve and valve seat.  Then, he could turn the valve against the cloth and clean the seating area even better.  I’m also going to keep that little tip in mind for my next lapping project.  Thanks Drew!The seating area of the valve showed a nice smooth band after the lapping was done – very impressive!After the lapping was completed, a new rotator was installed on the exhaust valve, everything was reassembled, and the compression immediately improved!  But the best result was the compression test that was done after running the engine… that same cylinder that was 42/80, now had a compression of 78/80!  What a fantastic result, and now, hopefully that cylinder will run reliably for many more hours.Be sure to listen to the audio for this episode for more details about Drew’s adventure.  He also shared about an induction leak that was visible because of some blue fuel staining.After removing the intake pipe, it was obvious the gasket had shifted out of position during the assembly process many years ago… perhaps this was part of the poor idling problem that was also corrected during the annual inspection.  After installing a new intake gasket and adjusting the idle mixture setting, the engine idled much better than before.Drew’s story is a true inspiration in so many ways.  So, if you, as an airplane owner, have an interest in learning and getting involved in the maintenance, just find an A&amp;P who is willing to give you some supervision to keep things legal, and you’ll have all kinds of possibilities.Well done Drew, on your exhaust valve lapping project!  I’m thrilled with the result you achieved on this one!  Drew has a young family, and it makes me happy to know he’s taking such good care of his airplane… after all, he’s got some precious cargo to haul around!

131 – Drew Wright’s Cessna 182 Exhaust Valve Lapping Success!

Happy New Year Friends! This week on the podcast, we’re talking about simple fixes with just a little lubrication.  Sometimes on airplanes, there are parts that might need some lube, that can easily be overlooked.  We have several of these examples in today’s episode.  Here they are:  A Beechcraft Debonair with a starter problem. A Mooney M20J with a speedbrake issue. An A36 Bonanza with a “GND COMM” switch that would not turn off. An Aerostar with a nose gear steering problem.  In the end, all of these situations were solved with some simple lubrication… spray silicone, LPS-1, and a grease gun with a special adapter, were what solved the problems.  Listen to the audio to get the details, and consider any areas on your airplane that might need a little lube. AND… be looking for some pictures on Instagram in the near future… I’m planning to open an Instagram account for Airplane Owner Maintenance real soon. Have  a great weekend!

107 – Avoid Costly Repairs With A Little Lube

My friend Matt and I had a plan, and it was going to be an awesome adventure.  The crisp, clear morning was as nice as we could hope for on a November day in Virginia.  The half hour drive from my house to the small town New Market Airport was absolutely refreshing… exhilarating even. As I pulled onto the airport drive, I didn’t go far before I was compelled to back up and take a picture of the signs that arrested my attention.  “DEAD END STREET” AND “LEARN TO FLY HERE” just did not seem to fit together in my mind.  As I think about it, I wish I could replace that top sign with “PATHWAY TO POSSIBILITIES!” For me, and for my friend Matt, we had far more in mind that day than any dead end street.  If our planned adventure came together, we would be flying a little Cessna 150 to Tangier Island (KTGI) and maybe having a crab cake sandwich for lunch.  But first, we had to solve a problem… a report of “No oil pressure.”   We struggled to get the “barn doors” open in the old rustic hangar, and the site looked so familiar for these old airports, complete with gravel floor, a motorcycle off to the side, as well as a Cessna 120 and another Cessna 150.  I was actually pleasantly surprised when I saw the good condition of the airplane we’d be working on. We decided to go ahead and start the engine and see if we got any oil pressure within 30 seconds.  The engine started nicely and within seconds, we saw the oil pressure needle creeping up… good news indeed.  However, after some warm-up time, we noticed the oil pressure needle went back down, and was approaching the red line at the bottom of the gauge.  (It had never made it up to the green arc.) So we shut down, and decided to see if the oil pressure line had any air in it.  Thankfully, the gauge was very accessible at the bottom of the pilot instrument panel.  After loosening the nut for the oil pressure line behind the gauge, there was not even a drop of oil there.  So we attempted to motor the engine with the starter to get the air out of the line. Now we had another problem… low battery power!  The engine wouldn’t even turn over more than a turn or so.  Back to troubleshooting,  except now in the electrical system.   Matt suspected the alternator was not working, and this proved to be true when we discovered no voltage at the field terminal on the back of the alternator when we turned the master switch on. Then something jumped out at me… I was standing over on the left side of the engine, and I noticed the whole wiring harness plug was disconnected from the voltage regulator at the firewall.  Take a look. Amazing how well things work when all the wiring is connected properly! So after charging the battery, we tried again to purge the air out of the oil pressure line.  Matt motored the engine with the starter for maybe 30 seconds, and just as he let off the starter, I saw oil seeping out at the gauge connection… success, finally! This time, after starting, the oil pressure climbed up in the green arc, and stayed there during the runup. Now, how about Tangier Island?  Could we still go? Nope… I noticed the maintenance records were in the back of the airplane, and the airplane was still in annual… sort of.  The main thing is there was some lacking documentation that made it unwise to fly the airplane until it was resolved.  Mechanically, I totally would have been confident to go flying in that airplane with Matt.  But paperwork-wise, the issue needed to be resolved. That’s ok… instead of lunch at Tangier Island, Matt and I had breakfast at Dunkin Donuts.  And… we’re not giving up on the Tangier Island idea.  In fact, after thinking about the whole thing, I did some research, and discovered a young man named Swayne Martin, who gave me even more motivation to visit Tangier Island.  He and his brother flew their mom there in a Cessna 172 several years ago as a mother’s day gift!  If you’re interested, his post is very interesting. Flight To Tangier Island (KTGI) For Mother’s Day You may recognize Swayne from his involvement with the Boldmethod online flight training resources.  He also has an excellent YouTube channel.  I also found out he has gone on to become a first officer with one of the regional airlines.  Well done Swayne!   Now back to Tangier Island… Matt and I are not giving up, and I’m confident we’ll still get there one of these days… very possibly in that very Cessna 150 we worked on.  And when we do, you’ll hear about it, because it will no-doubt be an excellent adventure for another podcast episode! It really was a great day, and the sunset view of my neighbor’s field from my back yard, was just as fantastic as the sunrise view on the way to the New Market Airport. Days like this make me say, “Thank you Lord, it’s good to be alive!”

127 – No Oil Pressure in a Cessna 150

Not long ago, there was an unusual engine failure in a Cessna 182 at Shenandoah Valley Regional Airport.   Cindy Ferek was the flight instructor on board that day, and she landed the airplane safely on the runway.  Before we get into that story, I’d like to introduce Cindy.  (The Cessna 172 in the following picture is not the airplane that had the engine failure.)  Cindy taught high school physical education for 21 years at Turner Ashby High School, which gave her an excellent teaching foundation that she uses today as she skillfully works with students in the cockpit of airplanes.  Not only is Cindy an excellent flight instructor, but she’s also just an inspiring person to be around!  I hope you’ll listen to the podcast to hear about more of Cindy’s story, both in and out of the airplane. The engine failure we talked about in today’s episode, happened in the traffic pattern, thankfully.  Here’s the airplane after they landed safely and parked it in the grass to save the engine: Shortly after their successful landing, one of the line guys tugged the airplane up to the maintenance shop.  At first it was challenging to figure out what actually happened to the engine, because there was no external evidence of any problems.  But a borescope inspection revealed the exhaust valve in cylinder #1 was not opening at all.  And after removing the rocker cover, it became really obvious.  The rocker arm shaft boss had broken apart and the rocker arm could not operate the exhaust valve.   Thank you Cindy, for sharing a bit of your aviation journey and your engine failure story with us, and for all the excellent work you do to make aviation such an inspiring endeavor to pursue!   For those of you who would like to contact Cindy, there are multiple ways to get in touch with her.  (And she would love to hear from you.)

125 – Engine Failure – What Would You Do In A Moment’s Notice?

Whether your airplane has a “Brackett” brand filter like the first picture, or a “Donaldson” brand filter like the second filter, or another brand like “Challenger” or something else, they all need to be clean and in good condition. The air your airplane breathes is critically important.  Your engine, your vacuum instruments, and even other components, all need to breathe fresh clean air in order to function properly. Listen to today’s episode to hear about induction filters, vacuum system filters, and even an obscure filter you may not have thought about.   Take a look at what can happen when a Brackett filter is not changed often enough.  Upon removal, the foam filter crumbled apart.  Brackett filters have an expiration date on the package… while they work very well when they’re in good condition, they can also fall apart when they are expired.  Don’t install an expired filter! Vacuum systems also need clean filters.  Check out this vacuum regulator filter that is covered with dust… this thing has been here for years!  Compare this with the new filter that needs to be installed.  This filter is sometimes overlooked at the annual inspection.  The part number is B-3-5-1.  Or, if you buy a Rapco filter, it’s RAB-3-5-1.     The vacuum inlet filter is also an important one to keep clean, so that your vacuum instruments, like the attitude indicator and directional gyro, can breathe nice, clean air.  Here’s an example of an old, dirty vacuum inlet filter, compared with a new, clean one: Clean air filers are vitally important! Another obscure filter I encountered recently was on an Aerostar 601P.  This airplane has a Sandel SN3308 electronic HSI.  The internal lamp needs to be changed at regular intervals.  Upon removing the unit from the instrument panel, I discovered the fan filter in the bottom of the tray was falling apart.  Take a look at the view from under the instrument panel, and how little was left of the foam filter: The fan pulls air in through the bottom of the instrument tray, for cooling. It’s a bit of an obscure air filter, but still an important one.   A call to Sandel was very helpful.  Although the new filter is a fairly thin, coarse mesh piece of foam, it actually has a part number, and the price was reasonable ($8.)  Check it out in the following picture: The HSI is now breathing clean air again. So… whether it’s an airplane’s induction filter, a vacuum system filter, an instrument filter, or some other filter, it’s important for all these filters to be clean and in good condition.   Take a look at your filters, and make sure your airplane is breathing nice clean air.  Your engine, your vacuum system, and your instruments, will thank you in the form of reliable performance  Filters discussed in this episode: Brackett induction filters. Donaldson induction filters. Challenger Aviation induction filters. Vacuum inlet and regulator filters. Sandel HSI cooling fan filter.

Whether your airplane has a “Brackett” brand filter like the first picture, or a “Donaldson” brand filter like the second filter, or another brand like “Challenger” or something else, they all need to be clean and in good condition. The air your airplane breathes is critically important. Your engine, your vacuum instruments, and even other components, all need to breathe fresh clean air in order to function properly. Listen to today’s episode to hear about induction filters, vacuum system filters, and even an obscure filter you may not have thought about. Take a look at what can happen when a Brackett filter is not changed often enough. Upon removal, the foam filter crumbled apart. Brackett filters have an expiration date on the package… while they work very well when they’re in good condition, they can also fall apart when they are expired. Don’t install an expired filter! Vacuum systems also need clean filters. Check out this vacuum regulator filter that is covered with dust… this thing has been here for years! Compare this with the new filter that needs to be installed. This filter is sometimes overlooked at the annual inspection. The part number is B-3-5-1. Or, if you buy a Rapco filter, it’s RAB-3-5-1. The vacuum inlet filter is also an important one to keep clean, so that your vacuum instruments, like the attitude indicator and directional gyro, can breathe nice, clean air. Here’s an example of an old, dirty vacuum inlet filter, compared with a new, clean one: Clean air filers are vitally important! Another obscure filter I encountered recently was on an Aerostar 601P. This airplane has a Sandel SN3308 electronic HSI. The internal lamp needs to be changed at regular intervals. Upon removing the unit from the instrument panel, I discovered the fan filter in the bottom of the tray was falling apart.

129 – Air Filters: Don’t Let Your Airplane Suffocate!

Sometimes small, general aviation airplanes get too much maintenance, and sometimes they get too little.  We talk about that in today’s episode along with some real life examples. But first, I want to give a shout out to two people I have absolutely loved learning from recently because they are both excellent teachers. Chris Palmer:  Aviator and flight instructor living in Homer, Alaska.  I’ve been going through Chris’ online instrument ground school course, and it is absolutely amazing.  Stunningly excellent graphics, interesting and engaging teaching, and the best review of the FAA test questions I’ve ever seen.  Check out his courses and training here: http://AviatorTraining.com ——————————————————————————————————————– Carl Valeri:  Airline pilot, podcaster, and aviation careers coach.  Carl is the host of the Aviation Careers Podcast, and he shares a TON of great useful information about flying and aviation careers in a really fun and inspiring way.  If you want to make progress in your flying career, you MUST check out Carl’s podcast and resources.  You can find his podcast in iTunes or other podcast apps, and his website is here: AviationCareersPodcast.com Listen to today’s episode to hear about some things that got my attention last week at Classic Aviation:  A one time AD that keeps getting signed off year after year.A purple paperclip on a jet at Shenandoah Valley.A couple examples of too much maintenance.One example of not enough maintenance. Here’s the purple paperclip: Not something I would expect to see on a jet like this   And here’s my example of “not enough maintenance.”: That induction filter had not been changed in a long time, as evidenced by it falling apart when I removed it. Here’s the recommendation to change these filters every year… it’s right there on the package of the new filter: You can hear more details of all these items by listening to today’s audio. ——————————————————————————————————————– Finally, if you’re going to Oshkosh, I’d love to meet you.  I’ll be presenting a talk on Saturday morning, July 27 at 8:30 am.  The topic is “Exhaust Valve Borescoping and Lapping.”  I’d love to meet you there. Have a great week!

118 – Airplane Maintenance:  Too Much or Too Little?

Is there ever a good reason to fire an A&amp;P? I think so… and in today’s episode, we’ll talk about some evidence for one of those times.  Scroll down for the appalling pictures I took recently! But before that, I want to share some inspiring information related to the amazing Stinson family of airplanes.  And… if you are as involved in your airplane’s maintenance as Bret Chilcott and Randy Phillips, the chances are slim to none that you’ll ever find yourself in a situation where you need to fire your A&amp;P.  You’ll be so involved in the process, that you naturally work with an A&amp;P and IA who are competent, skilled, and very professional. Here’s a video from Bret Chilcott.  He sent this to me a good while back when he was changing a cylinder on his Stinson 108 airplane… I love the color of his airplane!  Thanks for the video Bret!  You’re one of my airplane owner heroes! And for you Stinson owners, (and perhaps others as well, because the Stinson guys are so inspiring,) here’s a link to the Stinson Tech Channel on YouTube, which is managed by Randy Phillips, another great guy.  Listen to today’s episode to hear an audio clip from Randy. https://www.youtube.com/channel/UCrQVOk7qUlVTTXH8hJpdQjg Randy mentioned something I have not thought much about… the “Owner assisted engine overhaul.”  What a fascinating idea!  I’m interested in learning more about that one… thanks Randy! One more really helpful contact for Stinson airplanes and for Franklin engines, is Jack Stewart.  Jack is the A&amp;P / IA who Randy Phillips worked with to overhaul his airplane engine awhile back.  He’s very knowledgeable and here’s a link for a YouTube video of a Franklin engine seminar by Jack: Now for a totally different topic. I discovered something awhile ago on a Cessna airplane that was absolutely appalling to me, and I thought I’d share some pictures and some thoughts that came to my mind about “When to fire an A&amp;P.” It’s rare that I see something this appalling on an airplane, but I thought this one was so bad, I’d talk about it in today’s episode and share some pictures.  It was also a good opportunity for me to use my borescope, since I had to take most of these pictures under the floor of this airplane. Here is a sampling of what I found on a seat track installation in a Cessna airplane…  I could hardly believe it!     Oops!  This rivet was obviously hit with a rivet gun, but was not bucked properly.    Oops!  They forgot to put a nut on this screw.    Oops!  Lots of mis-drilled holes.    Oops!  Rivets too short, and holes too large.  Also check out the butchered holes to the left.    Oops!  Left rivet:  Too short, deformed, and hole too large.  Right Cherry Max rivet:  Hole too large, and rivet not seated properly.    Oops!  A piece of seat track installed UNDER the floor!?!?    Oops!  Rivet hole way to large.    Oops!  Blind rivets not seated properly… the center stem and locking collar should be visible and flush with the surface of the rivet head.    Oops!  Extra, unused holes in the seat track.    Oops!  This rivet was pulled crooked and did not seat properly.    And for the final oops… they didn’t even bother to clean out the shavings and old rivet tails under the floor.      So… what about all this? If I found any one of these situations in the previous pictures on an airplane, and it was an isolated issue by itself, I’d probably just fix it and go on without thinking too much about it.  But to have so many issues on the same installation… that’s just incompetent at best, and even might be considered beyond negligent. Perhaps, this is one time when it would be appropriate to “Fire an A&amp;P.”  I certainly would not want this person anywhere near my airplane engine, or any other critical part of the airplane.  This, to me, is totally unacceptable, and it got me thinking about when it might be appropriate to “Fire an A&amp;P.”  And I thought of several times.  Here they are: If they are deceptive, and you can’t trust them.If interactions with them are continually frustrating.If there is continuous lack of communication.And… if they do something like the butchered seat track installation in these pictures. Thankfully, A&amp;P’s are usually skilled, dependable, and conscientious.  But for some rare occasions, there might be a time to “Fire an A&amp;P.”   My challenge for all of us:  Be the best you can be, in the situation you’re in! And for all A&amp;P’s and IA’s who are doing excellent work:  Well done my friends!  You have a very important job and people are counting on you.  Keep up the good work!
