## Discrepancy

ENGINE FAILURE OCCURRED UPON REACHING 4,500 FEET.  EMERGENCY LANDING AT AIRPORT WAS MADE.  INVESTIGATION DETERMINED MAGNETO HAD FALLEN OFF ENGINE.  INSPECTION REVEALED MAGNETO HAD BEEN REMOVED 4 MONTHS EARLIER TO C/W AD 78-09-07RE.  UPON REINSTALLATION OF MAGNETO, A FLANGED TYPE GASKET P/N 62224 HAD BEEN USED INSTEAD OF PROPER ROUND GASKET, P/N CW12681.  THIS ALLOWED GASKET MATERIAL TO BE COMPRESSED BETWEEN MAGNETO HOLD-DOWN CLAMPS AND ACCESSORY HOUSING RESULTING IN IMPROPER TORQUING AND SUBSEQUENT FAILURE.
