THE CRANKSHAFT, P/N631716, HAD BROKEN IN THE CHEEK AREA BETWEEN #2 & #3 CRANK THROWS. 1 MONTH PRIOR TO THIS ACCIDENT THE ACFT HAD COLLIDED WITH A FENCE. AFTERINSTALLING A NEW PROP THE ACFT WAS RETURNED TO SERVICE WITHOUT OVERHAULING THE ENG. TCM SERV BULLETIN M71-5 (EXAMINATION OF ENGS INVOLVED IN PROP STRIKE ACCIDENTS) STATES, IN PART, THAT THE ONLY SURE METHOD OF INSPECTING FOR INTERNAL DAMAGE IS COMPLETE ENG DISASSEMBLY & MAGNETIC PARTICLE INSPECTION OF THE CRANKSHAFT GEARS, ETC.
