Wanted to get some opinions on various shops people use around the country for 500 hr magneto inspection and their experiences.

 

Are there shops that are better than others?

 

Any input is greatly appreciated!

There's two that are pretty much at the top of the list. One is Select Aircraft Services in Lancaster, Texas. The other is Aircraft Magneto Service in Bainbridge Island, WA. I used Select Aircraft Services and Aaron Williams is top notch. You will not find anyone better. Other folks really like Aircraft Magneto Service.

Don Maxwell uses Select Aircraft Services and Mike Busch uses Aircraft Magneto Service. Can't go wrong with either choice.

I spoke with Cliff of Aircraft Magneto Service and he indicated they don't work on the dual mag because parts issue.

 

He indicated that PMA parts are available and Kelly Aerospace will do an OH exchange. I haven't called anyone else yet.

Thank you Gary, Scott and Brett.

Looks like Aaron at Select is going to be my choice as well. He also was the most reasonable for the 500 hour.

Did you guys have the plastic gears replaced as part of the 500 hour as a precaution even though they may not have severely discolored?

They are a couple hundred dollars a piece those gears!

PTK,

Colorado is a long way from NJ but if you want to get a good inspection try Crossfire Magneto Service (970) 672 6505.  Located in Loveland, CO at FNL.

When I spoke with him on the phone Aaron said around 800$.

Please don't hold him or me to it! He was the most reasonable. Others were at 1000$ or more.

Thank you FoxMike!

Colorado has a very special place in my wife's and in my heart!

We took our twin boys when they were 6 on their first skiing trip to Breckenridge.

We absolutely loved it! We're coming back next month!

What are the plastic gears replaced with? A metal such as aluminum or brass?

Ozone is a powerful oxidizer. Usually nylon will turn brownish with oxidation and get brittle. Nylon gears in GM headlight systems (corvette and firebird) are known for becoming brittle and losing teeth under torque, They don't show much age when they fail.

I would be inclined to swap out the plastic gears with metal if the failure mode of the gear leads to failure of both magnetos.

If they are two separate magnetos, a complete failure of both would be remote. If one fails, the other won't be far behind...

Sorry to mix cars and Mooneys,

I think they change those on condition. I think the only difference between an OH magento and a 500hr inspection is the replacement of the magneto bearings.  They can look at everything in the mag, decide its good, change the shaft bearings, and call it overhauled.  FWIW we had 4 Slick magneto coils in our shop that failed in the past 6 weeks. So I am a Bendix man.
