Airplane Owner Maintenance - By Dean Showalter

I received an email recently from Spence, the owner of an S35 Bonanza with a Turbo-Normalized IO-520 engine. He included a picture of his #2 cylinder exhaust valve. Here’s what it looked like: At first glance, my reaction was something like, “Oooh, that’s ugly!” The most concerning area is the spot at the 10 o’clock […]

I got an email from Michael this past week. He owns a Mooney M20J, and something strange happened with cylinder #1’s EGT and CHT recently. Michael agreed to let me share the story, so that’s the main feature in this episode. The picture above is one Michael took with his borescope while looking for any […]

12/80! That’s a terrible compression test result. And unlike some cylinders, this one did not show any obvious reasons for the low compression… take a look at the valves after the cylinder was removed: Unless I’m missing something, I don’t see anything that would explain such a low compression number. The cylinder has been shipped […]

Can you see the problem with this exhaust muffler? Maybe a closer look will help: (The cracked area was just inside the shroud that collects heat for the cabin.) Thankfully Matt, the owner of a nice Cessna 170, had a carbon monoxide detector in his airplane that picked up the small amount of “bad gas […]

I had a surprise call this morning… my friend Eddie called and wondered if he could borrow a borescope. One of the cylinders in his Sonex’s Jabiru engine had zero compression, and he wanted to take a look inside the cylinder, especially at the exhaust valve. Since I’m always looking for a good story, it […]

Our guest for today’s episode is Autumn Duntz, an aviation interior designer and refurbishment expert… welcome Autumn! After observing some poor quality elements in a newly refurbished Beechcraft A36 Bonanza interior, I wondered how this type of thing could be avoided. After a little online research, I found Autumn’s website, AutumnElizabethDesign.com. I quickly realized she […]

Does your airplane have emergency exit windows? If so, would your passengers know how to operate them? Here’s an emergency exit window where the instructions were hardly readable: Thankfully, the lettering was etched into the panels, and a fine point Sharpie did the trick: Imagine trying to remove that window if you were completely unfamiliar… […]

In a previous episode, I shared the story about how I accidentally left a shop towel in an engine… I got some great feedback from that episode, including the picture above… a flight student found a shop towel during preflight… in a place you would not expect. It’s one more reminder to be extra-diligent during […]

Lieutenant Commander (LCDR) James Cox, a member of the Navy’s Blue Angels Team, is our guest today on the podcast! He exceeded my expectations in so many ways in our conversation, and I’m thrilled to share this interview with you. You’ll definitely want to listen to this one! Although the Blue Angels do a lot […]

Hi Friends! I have a story for you today that I wish I didn’t have. But it’s true, so we might as well learn from it. Thankfully, everything turned out well on this one. At Moody Aviation where I went to school years ago, we had a concept called “SYE.” It stood for “Share Your […]

Bob Shenk (right) is a huge fan of Luscombes… this beautifully restored aircraft was among the airplanes I got to see when I visited Bob’s place a week ago… what a pleasure that visit was! Donnie Simmons (left) is a good friend of Bob’s, and often spends his Fridays at Bob’s place, both helping with […]

I recently did an annual inspection on a Rockwell Commander, and the gear warning light was not working. Before we tell that story, I want to thank our sponsor, PilotWorkshops.com This week’s “Tip of the Week” was about emergency checklist memorization… a very interesting lesson by Sarah Fritts, a West Point graduate and Army combat […]

Without Jonathan Brush, this podcast might not exist! I’m super-thankful for his part in pushing me to launch this whole thing. I think you’ll enjoy the conversation with him today. At the end of the podcast, I asked Jonathan to talk a little about the organization he leads, called Unbound. If you’re curious after hearing […]

Jessica is our special guest on the podcast today. She and her husband Mark, along with their 5 kids, are serving with a mission organization in Cameroon, Africa. Mark flies helicopters, and Jessica works in the maintenance shop, with plans to get her A&P certificate. I think you’ll enjoy her story! Instagram: Spanglers_in_Cameroon Check out […]

I’m so glad I got talked into this one! (Thanks Kenneth!) It turned out to be a definite highlight of the week… you can hear more about the details in the podcast audio. I want to thank PilotWorkshops.com for sponsoring the podcast. The book, “Airplane Engines: A Pilot Friendly Manual” is a resource you’ll love. […]

I installed this starter and starter adapter on a Beechcraft Debonair IO-470 engine last week… the starter adapters (or sometimes called a clutch, or starter drive,) sometimes begin to slip, and when that happens, it’s time for overhaul. It’s also recommended to overhaul the starter at the same time, or install a new one. There […]

Valve lapping is sometimes a great option for improving cylinder compression and extending the life of an exhaust valve. We’ll talk about it in today’s episode. Pilot Workshops.com is our sponsor for this episode, and I wholeheartedly recommend their resources. Be sure to sign up for the “Tip of the Week,” and receive a short, […]

Although a shop vac might not pull as much vacuum as an engine driven vacuum pump, it can still be useful for some parts of the troubleshooting process. This was just one thing we did on the path to solving a very strange vacuum problem. Listen to the story in today’s podcast episode. Our sponsor […]

This is what Josh discovered recently in his Beechcraft Debonair while getting some training in his airplane with an instructor as part of the Bonanza Pilot Proficiency Program (BPPP.) The gear motor was the culprit. Josh’s story is the main feature in today’s episode, but first I want to thank PilotWorkshops for sponsoring the podcast. […]
