  • Essential listening for aircraft mechanics, owners and industry regulators

    Ask the A&P’s is a regular feature of my podcast schedule.

    Not only does it inform and educate, it’s got enough Click and Clack to it (NPR reference) that it’s a fun listen too.

    What it does best though is to remind us that data helps guide the diagnosis of a lot of problems and that less is often more when it comes to maintaining an aircraft.

  • Start from the beginning?

    About 6 months ago I listened to the two most recent episodes of Ask the A&Ps. I liked it so much and recognized the value of the info I was hearing, I immediately started listening from the very beginning of the series! I thoroughly enjoy the format and topics discussed. Thank you for everything.

  • Good information

    There is so much folk lore, and old tom-foolery information in aviation, pilots especially, need sources of reality like this to set the record straight.

Talking Points

Recent interactions between the hosts and their guests.

"We're in the twenty-first century here folks"
Q: What is the best way to handle a lean-of-peak situation on a carbureted engine?
Keep the engine smooth and within temperature limits, use lean-of-peak to reduce detonation risk, and rely on engine monitoring, thermocouples, and CHTs to verify a healthy mix, adjusting based on altitude and power needs.
"It's in your head"
Q: Does the turbo remain naturally aspirated when the engine is off, and what about starting procedures at high density altitude?
The turbo is effectively idle until exhaust pressure builds and the wastegate opens after startup; starting hot or cold follows standard procedures with rich mixtures on cold starts and purging strategies for Continentals, plus the possibility of ground-lead lean considerations.
"Your mechanic feels worse than you do"
Q: Scott asks about drying out oil and dealing with morning sickness and related valve issues in a Lycoming-based engine.
The panel explains condensation and water in the crankcase after shutdown, discusses use of oil dehumidifier and CamGuard, describes wobble tests for exhaust valve guides, and provides procedural steps for cleaning and reseating valves to extend engine life.
"Your mechanic feels worse than you do"
Q: Scott asks about a safety wire alternative and whether FAA certification is required for the Bergen/DMC tool.
The hosts and Scott discuss minor alterations and FAA certification implications, conclude that using a safety wire tool is a minor alteration possibly permissible, and encourage checking with the authority while considering community usage and proper calibration of the tool.
"Your mechanic feels worse than you do"
Q: Matt asks about octane changes when switching to 91 octane auto fuel and whether ignition timing needs changing.
Experts explain that autofuel octane is not directly comparable to avgas octane, advise not to advance timing, note that higher octane reduces detonation risk, and discuss timing values for a Continental O-200 with an appropriate STC, concluding that the one-to-one octane relationship does not hold and timing adjustments are generally not recommended.
