10-349370-4 - Kelly 1200 Series Magneto

Kelly Aerospace's CMI/TCM/Bendix Magneto part number 10-349370-4  is a single aircraft magneto built for various six-cylinder Continental aircraft engines. This mag differentiates itself from other aircraft mags in that it is an impulse type mag, this particular mag is also left-hand rotation and the mag will include the mag gasket.

* The mag does NOT come with the drive gear. Remove your drive gear before sending us the core.

****** CRITICAL TO NOTE ****** YOU MUST CHECK YOUR MAG HOUSING TO MAKE SURE THE HOUSING HAS THE THREE CAST-IN BRACES ON EACH SIDE OF THE HOUSING. IF YOUR MAGNETO HAS THE THREE CAST-IN BRACES ON EACH SIDE, AS PICTURED BELOW, YOUR MAGNETO IS ABLE TO BE OVERHAULED. IF YOUR MAGNETO DOES NOT HAVE THE THREE CAST-IN BRACES AS PICTURED BELOW, YOU WILL FORFEIT YOUR CORE CHARGE AS YOUR MAG HOUSING IS UNABLE TO BE USED FOR OVERHAULING YOUR MAGNETO.

OEM Part Number:  S6LN-1227
TCM Part Number:  C209309F

This mag will fit the engines listed below. This list is not a complete list, make sure to verify that you are ordering the right mag for your aircraft before placing your order. 

Your core return must match the same mag you purchase from AirParts. Your core return mag will be immediately inspected for non-standard damage and wear. If there are any items in the overhaul of your core return that exceed standard overhaul charges, you will be "billed back" for those costs. Additionally, your mag core return may not be accepted if damaged beyond economical repair.

How is an aircraft magneto like this overhauled?
Generally, overhauling an impulse-based aircraft magneto will require adherence to the mag's overhaul manual and will include all the parts necessary to basically rebuild the mag and return it to like-new condition. Once that is done, an 8130-3 document will be issued against that magneto that will comply with FAA and EASA regulations. To comply, the mag will undergo extensive rework which includes repainting the body, replacing points, condensers, brushes, impulse springs, and the pinion gear. New bearings are installed and then the mag is tested to verify proper operation.


Will this mag require a 500-hour inspection?
YES! TCM, CMI, and Bendix mags require an inspection at the 500-hour interval mark under an airworthiness directive (AD 2005-12-06)  MSB645. Make sure to plan for that in terms of time and finances.

Is there a core charge for this mag?
Yes, the core charge is $600.00. This core charge will be held until your core mag completes the inspection, prior to the overhaul of your returned core mag. Once the mag has been accepted for overhaul, AirParts will return your core deposit. Core deposits are not refunded if your mag is returned to us after 30 days.
