Makes named: champion, continental, teledyne, slick, champion aerospace. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to TCM and R-RM C-125, C-145, O-300, IO-360, TSIO-360, and LTSIO-520-AE series reciprocating engines with Champion Aerospace (formerly Unison Industries) Slick Magnetos, models 6314, 6324, and 6364, with magneto serial numbers (S/Ns) of 99110001 through 99129999, inclusive.
Compliance
Replace any magneto that has an S/N of 99110001 through 99129999, inclusive, with a magneto that does not have a serial number in that range. If a magneto is not in this S/N range, no further action is required by this AD.
Required actions
Inspect each removed magneto to verify that the impulse coupling stop pin is present. If the pin is missing, do the following: (1) For C-125, C-145, O-300, IO-360, and TSIO-360 series engines, do the following: (i) Remove magnetos, alternator or generator, and starter adapter from the accessory case. (ii) Remove the accessory case from the crankcase and oil sump. (iii) Visually inspect the entire engine gear train for damaged or broken gears and gear teeth. (iv) Inspect visible portions of the engine crankcase and accessory case for damage due to the stop pin becoming lodged between the engine gear train and the crankcase or accessory case. (v) If the accessory case is damaged, repair or replace the accessory case. (vi) If the engine crankcase is damaged, disassemble the engine, and repair or replace the crankcase. (vii) Inspect the oil pump drive gear teeth and inner cam gear teeth for damage. Replace any engine drive train component that has been damaged. (viii) Replace any damaged gear, and magnaflux the mating gears using the applicable engine overhaul manual. (2) For LTSIO-520-AE series engines, do the following: (i) Remove the starter adapter, fuel pump, vacuum pumps, accessory drive pads, and both magnetos. (ii) Visually inspect the entire engine gear train for damaged or broken gears and gear teeth. (iii) If any damage has occurred, remove the engine from the airplane, disassemble the engine, and inspect it for damage. If any damage is found, repair as necessary. (iv) Replace any damaged gear, and magnaflux the mating gears using the applicable engine overhaul manual. (v) Inspect the interior portions of the engine crankcase for damage due to the stop pin becoming lodged between the gear train and the crankcase. If the crankcase is damaged, repair or replace the crankcase.

You just looked this one up by hand
TrackAD holds all 12,278 of them and matches them against the aircraft you actually look after — airframe, engine, propeller and appliances in one pass — then works out what falls due and when.
- Bring your existing list in from a spreadsheet Paste the rows straight out of Excel. Headers like C/W Date and N/A are read for you.
- A copy that works when this does not One file. No internet, no login, no this software running. For the morning something has to be produced and the computer is not cooperating.
- $5 a month, or $50 a year Up to 50 aircraft on either.
