176 – Lessons From the Best Kind of Airplane Owner

A nice airplane deserves a high-quality owner, and that’s exactly what this amazing P35 Bonanza has. Aram takes meticulously good care of it.

In today’s episode, you’ll hear why I think Aram is the best kind of airplane owner, and some lessons you might want to consider for maintaining your airplane as well.

lf you haven’t listened to episode 147, be sure to check that one out to hear an interview with Aram.

Also, the list of “My Aviation Pet Peeves” came from episode 023, in case you’d like to check that one out as well.


Other podcast listeners mentioned in this episode:

Andy Klauser: His voice message is in today’s podcast.

Janette Wohn: She drives farm equipment while dreaming about flying and airplane maintenance. Check out a couple photos from the farm:

Janette has an eagle eye for spotting airplanes as they fly by.

Let’s wish her well as she makes plans to go off to A&P school this fall!

Drew Wright: He flies a Cessna 182 and recently took his family on a big trip across the country. Drew saved a cylinder awhile back by lapping the exhaust valve and installing a new rotator. (The interview with him is in episode 131.) The compression improved dramatically and his engine is running great! Drew also sent me a very interesting article from many years ago about the improvements in the 1957 Cessna 182! Apparently, that’s when they introduced the “rotator” for the exhaust valve. Very interesting indeed!

Spence Watson: He is having great success with the exhaust valve we lapped a few weeks ago… it was the one with the broken spring inside the rotocoil. His story was in episode 174. I was shocked how much the appearance of the exhaust valve improved in just 5 hours of operation since lapping and installing the new rotocoil. Listen to this episode to find out about Spence’s experience at a recent ABS service clinic.

Chris’ intake valve… I’m still waiting for the rest of this story, and hopefully we can share more in a future episode.


Remember, if you need help making sense of the photos you take of your exhaust valves and cylinders, I offer a service to help with that. Here are the rates:

$50 – 4 cylinder engine.

$70 – 6 cylinder engine.

$100 – twin engine.

Just send me an email if you’re interested and we can set it up dean@airplaneownermaintenance.com

121 – When to Fire an A&P

Is there ever a good reason to fire an A&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&P. You’ll be so involved in the process, that you naturally work with an A&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.

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&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&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&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&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&P’s are usually skilled, dependable, and conscientious. But for some rare occasions, there might be a time to “Fire an A&P.”

My challenge for all of us: Be the best you can be, in the situation you’re in!

And for all A&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!
