Superior Air Parts, Inc., Parts Manufacturer Approval (PMA) piston pins, Part Number (P/N) SA629690, shipped from Superior Air Parts, Inc., from August 1, 1994, through June 20, 1996, installed in Teledyne Continental Motors IO-360-A, -AB, -C, - CB, -D, -DB, -G, -GB, -H, -HB, -J, -JB, -K, -KB; LTSIO-360-E, -EB, - KB; TSIO-360-A, -AB, -B, -C, -CB, -D, -DB, -E, -F, -FB, -GB, -H, - HB, -JB, -KB, -LB, -MB series reciprocating engines which were overhauled or had cylinder head maintenance performed by a repair facility other than Teledyne Continental Motors after August 1, 1994. These engines are installed on but not limited to the following aircraft: Cessna 172XP, 336, 337, T337, P337, and T-41B/C (military); Maule M-4-210, M-4-210C, M-4-210S, M-4-210T, and M-5- 210C; Swift Museum Foundation, Inc.

This amendment adopts a new airworthiness directive (AD) that is applicable to Superior Air Parts, Inc., piston pins installed on Teledyne Continental Motors reciprocating engines. This amendment requires removal from service of defective piston pins, and replacement with serviceable parts. This amendment is prompted by reports of numerous piston pin fractures. The actions specified by this AD are intended to prevent a piston pin failure from causing secondary engine damage resulting in loss of oil or total power failure, and from causing jamming of the engine crankshaft resulting in a catastrophic engine failure.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
