## Analysis

THE ACFT HAD DEPARTED WOODBRIDGE, VA, EN ROUTE ATLANTIC CITY, NJ, FOR THE AFTERNOON. AS THE ACFT APPROACHED THE CHESAPEAKE BAY IN A CLIMB THE ENG LOST PWR. THE PLT WAS UNABLE TO RESTART THE ENG AND WAS FORCED TO LAND ON PVT PROPERTY. DURING THE EMERGENCY LANDING THE ACFT COLLIDED WITH TREES BEFORE COMING TO REST ON TERRAIN THAT LED UP TO RESIDENCES. EXAMINATION OF THE ENG REVEALED THAT THE SCREW AND LOCKPLATE WERE MISSING FROM THE CRANKSHAFT DRIVE GEAR AND THAT THE STEPPED DOWEL ON THE END OF THE CRANKSHAFT WAS FOUND SHEARED. THE CRANKSHAFT GEAR FITS INTO AND DRIVES THE ENG OIL PUMP.
