Last Monday, I lapped the #5 exhaust valve on a Continental engine. But more importantly, I met the owner / pilot of a Turbo Centurion, and now I’m happy to call him a good friend! Thanks for flying all the way up here Mark! Here’s the story: Mark had been a little concerned about the #5 exhaust valve, not because he was having any particular troub…

Everything looks normal in this photo, right? What we can’t see from this angle is the fact that the brake disc has broken in two pieces! Check it out: Here’s the story: The pilot landed the Piper Cherokee, and after a successful landing, something gave way on the left brake, and it became ineffective. Now we know why. It’s definitely time for new …

This story begins with a squawk from the owner. It went something like this: “When I fly my airplane, on the first landing gear retraction, the gear begins to move and then the “gear pump” circuit breaker pops. After I reset the circuit breaker, the gear retracts and extends normally with no further problems the rest of the trip.” Weird… What could…

The week I’m talking about here was almost too full! But I wouldn’t change a thing. A real highlight was taking my Pennsylvania cousin for a short flight in a Piper Cherokee: From Sunday to Friday, I had the following opportunities: Flew every day except Tuesday… this was unusual! Did an owner-assisted annual inspection on a Bonanza. Spent an after…

During a recent prebuy evaluation on this nice Beech A36 Bonanza, the question came up, “Does the old analog CHT gauge need to work in order for the airplane to be considered airworthy?” (In this case, the analog CHT gauge had an INOP placard on it.) Check it out: The airplane has a JPI engine monitor installed (bottom right in the previous photo,)…

This airplane appeared on the ramp not long ago at the Shenandoah Valley Airport in Virginia. I discovered it had taken off, and then very quickly made a 180 and returned for landing due to engine trouble. The pilot thought he may have lost a cylinder. His mechanic stopped by to check it out, and there was nothing blaringly wrong with the cylinder …

In this podcast episode, we’re talking about alternator maintenance! Here’s the alternator I removed from a Beechcraft Bonanza to inspect the drive coupling and the brushes… note the brush assembly in the lower right side of the photo: The brushes had plenty of length left, but they needed a good cleaning due to carbon dust that had collected from …

When it’s time to overhaul your engine, who do you call? Where do you go? Listen to this episode to hear ideas from other airplane owners who have had good experiences with various engine overhaul shops around the country. I always love meeting podcast listeners, and I was surprised when I met Ken Blow recently at the King Air Gathering in West Vir…

This ‘ol Piper Apache served me very well to get my MEI training and check ride done. Listen to the audio for this episode to hear how my check ride went… it was a challenging one! This part of the podcast is toward the end. This episode also covers something we did for our son Seth around the time of his birthday… we found someone to take him for …

Note: Scroll down to see who I unexpectedly met in Florida this past week! Now for the Prebuy… it was some months ago, and I did a prebuy inspection on a nice airplane on behalf of the buyer. I also became good friends with the owner / seller, for which I was grateful, because sometimes these can end up being sticky situations. The owner / seller (…

I’m excited, and I have a few butterflies as well… I just hope they are friendly butterflies Today’s podcast episode is about checkrides, and some encouragement for all of us to move forward with whatever that next step is… whether it’s a private pilot certificate, an instrument rating, or something else. …

Check out this spare parts case my friend Bill created! Although you might not want to carry that much extra stuff in YOUR airplane, it still might be worth thinking about some items to have in case of emergencies. This podcast episode will include the following: Some feedback from others about spare parts. A story about a communication blunder I m…

The paint was eroding on the King Air 350 prop blades. After a lot of research for paint and new Hartzell decals, I was ready to begin. Here’s where I bought the prop paint and new Hartzell decals: aerotouchups It was important to NOT get paint on anything other than the prop blades… Finally, after finishing the black and gray paint, it was time to…

I’ll get right to it… I think it was because one of the brushes in the heater combustion fan motor was severely worn, and when the motor / combustion fan did not run, the heater did not light. Here’s a comparison of the old brushes and the new brushes I just installed: (The 2 old brushes are on the left.) This episode also includes the nose gear su…

Mike Garcia has become a good friend over the past year or so. Recently we completed his annual inspection together, and he really enjoyed working on his airplane while learning more about what’s under the surface! Mike was my guest on the podcast this week, so be sure to listen to the audio for that conversation. Mike’s wife is also learning to fl…

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…

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 exam…

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 batte…

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 a…

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 …

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 cou…

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 ep…

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, i…

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&P certificate! Listen to the audio to find out how Chris pursued getting his A&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 we…

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…

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 …

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 a…

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 t…

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 difficul…

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 mag…

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 …

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 …

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 se…

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&P? Have you wanted to be an airline pilot for years and years? Did you give up along the way when you ra…

How long should the battery last in a small, piston-powered airplane? That’s a great question, and we are talking about it in this week’s podcast episode. Tune in to hear the story behind this 24 volt battery in the photo, as well as the story of another battery, a 12 volt one in a Citabria owned by our good friends, Leon and Wynne Johenning. (Find…

I had an opportunity to fly in an Aerostar the other day… it was going to be a fairly long trip to the destination, with one fuel stop along the way. As we climbed out of the Shenandoah Valley in Virginia toward the mountains to the West, we discovered the combustion heater for keeping the cabin warm was not working. After a brief conversation abou…

Recently, I had the amazing opportunity to visit NAS Pax River, a United States naval air station located in St. Mary’s County, Maryland, on the Chesapeake Bay. My friend, Trace Bowen, picked me up in his Cessna 310, flew me to St. Marys Airport, and drove me over to the base for a tour. Up until that day, I knew very little about Pax River, so it …

Have you ever seen one of these? It’s a SureFly Ignition Module, or “SIM” for short: I recently had an opportunity to install one on an E33A Bonanza, so I thought I’d do a podcast episode about it. Hopefully you’ll find this information helpful if you’re considering a SureFly, and for me, I find it helpful to document the process. For this installa…
