Q: What is Covered Under Aircraft Magneto Overhaul?

A: A normal aircraft magneto overhaul includes all parts required by the manual to issue an 8130 that states overhauled in box 12. These items can vary based on part number but normally this includes the points, carbon brush, condenser, oil seal, pinion gear and impulse spring if the aircraft magneto is impulse. They also completely disassemble the aircraft magneto, clean and paint the housings and install new bearings. The aircraft magnetos will then be tested and tagged with an overhauled 8130-3 that includes an EASA dual release.

Q: Are 500 Hour Inspections Required for Aircraft Magnetos?

A: An inspection of the magneto is required at 500 hour intervals under MSB645 (AD 2005-12-06) for some aircraft magnetos, specifically TCM/CMI/Bendix Magnetos.

Q: Is a drive gear included in an exchange? Or will you put one on my TCM/CMI/Bendix Magneto if I send it to you?

A: Drive gears are not included in any exchange for TCM/CMI/Bendix Magnetos. No drive gear will be installed on a magneto sent to us unless it was originally shipped to us with one and we will just re-install the same drive gear back onto the TCM/CMI/Bendix Magneto after servicing.
