Airplane Owner Maintenance - By Dean Showalter

This exhaust valve in a turbo-normalized A36 Bonanza looks quite good. The appearance is mostly concentric and uniform. There’s just that one area at about the 10 to 11 o’clock position that looks slightly uneven. If the compression test had been good, I likely would not have lapped the valve. But since it was 44/80 […]

It was a gorgeous VFR day, and we were flying in an Aerostar 601. The destination was an airport in Alabama and I was really looking forward to this trip. But soon after we leveled off at ten thousand feet and got the engines set and properly leaned, a strange but definite engine roughness occurred. […]

In the last podcast episode, we talked about an issue with my friend’s Cirrus SR22, and how the flaps occasionally would not retract. That problem got mostly resolved at the recent annual inspection when they made some adjustments due to the flap 50% and 100% travels being out of spec. However, there is now a […]

Don’t you just love intermittent problems?! This one has been just that… intermittent. In the 2005 Cirrus SR22, the flaps have 3 positions: up, 50%, and 100%. Our intermittent problem has been that occasionally, when selecting 50% or 100%, the flaps will begin to move down, but the “up” light will stay on. The flaps […]

This experience was a good one! (At least looking back in 2020 hindsight.) We had to dig deep to fix this one! I was about to give up and started thinking it might be time to take the airplane somewhere else for troubleshooting and repair. Thankfully Richard, our chief pilot, didn’t give up so easy […]

This morning I felt the inspiration to record a podcast episode… I got my hotel room set up with my computer and my microphone, and there it sat. I missed the window of opportunity… for whatever reasons, I did not record. And this afternoon, the inspiration was fading away. And then I remembered something. Often […]

(If you’re in a hurry, scroll down to see the tiny little chafed wire that caused this whole conundrum.) Now here’s the story… This landing gear relay breaker had been popping intermittently: It came time for annual inspection and we decided to replace the breaker with a new one, in order to rule out a […]

Bennett contacted me awhile back to see if I could lap an exhaust valve for him. The #4 exhaust valve showed a very uneven appearance when viewed with his borescope. Bennett flew in to KSHD one morning and we got started. Before lapping, we checked the cylinder compression and it was 29/80… not good. Here’s […]

If you look closely in the photo above, you can see my friend Chris, smiling. It was the day he arrived at Classic Aviation (KSHD) to begin his annual inspection with me. Chris is not only an airplane owner and pilot, but he’s also a certified airplane mechanic as well. I was very happy to […]

Today’s episode is about Pat’s Mooney, and how we sealed up some exhaust leaks. And it’s a fun story because Pat has become a good friend… check out the above photo where he’s showing his airplane to my grandson Spencer 🙂 Spencer and my daughter McKenzie stopped by the shop one day when Pat and […]

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 […]

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 […]

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 […]

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: Also, during the Bonanza inspection with my friend Mike, we adjusted the fuel quantity […]

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 […]

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 […]

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 […]

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 […]

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 […]
