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 maintenance, and to have another person look over your work before installing the cowling.

In this week’s episode, I’m sharing the feedback I got from the story of the shop towel in the engine. (If you missed that story, you can find it in episode 165.)

There are some really good lessons to be learned… I want to say a big “thank you” to everyone who sent me feedback and helpful stories.


I’ve been receiving messages from airplane owners who are performing borescope inspections on their engine cylinders and exhaust valves… I always love to hear those stories, because I’m convinced borescoping can make flying safer by detecting failing exhaust valves before they come apart in flight.

Do you have pictures of your exhaust valves, but you’re not sure what they mean?

I can help with that, for sure.

I offer a service to evaluate borescope pictures for airplane owners.

It’s very easy to work with me, and here’s the process:
