New spark plugs every year?

Yep… that’s what happened for five annual inspections in a row, with the A36 Bonanza I’ve been inspecting and working on.  From 2013 to 2017, the spark plugs were replaced every year.  Four of those times, the spark plugs being replaced, had less than 150 hours on them.  That is not a very long life for a spark plug, and I can’t imagine why they were replaced so soon.

Aviation massive spark plugs should easily last from 300-500 hours, and fine wire plugs should last at least 1000 hours, and perhaps more.

In today’s episode, we talk about several ways to maximize the life of your spark plugs:

1. Regular servicing, at least every 100 hours.
2. Rotate the spark plugs properly.  (Use a tray for this purpose.)
3. Avoid large bead blasters.  (Use a small one designed for spark plugs.)
4. Use proper torque when installing spark plugs.

These tips should help you maximize the life of your spark plugs, save you some money, and keep your engine running reliably and efficiently.

Happy New Year Friends!

This week on the podcast, we’re talking about simple fixes with just a little lubrication.  Sometimes on airplanes, there are parts that might need some lube, that can easily be overlooked.  We have several of these examples in today’s episode.  Here they are:

1. A Beechcraft Debonair with a starter problem.
2. A Mooney M20J with a speedbrake issue.
3. An A36 Bonanza with a “GND COMM” switch that would not turn off.
4. An Aerostar with a nose gear steering problem.

In the end, all of these situations were solved with some simple lubrication… spray silicone, LPS-1, and a grease gun with a special adapter, were what solved the problems.  Listen to the audio to get the details, and consider any areas on your airplane that might need a little lube.

AND… be looking for some pictures on Instagram in the near future… I’m planning to open an Instagram account for Airplane Owner Maintenance real soon.

Have  a great weekend!
