Analysis

During a local flight, the pilot noted that the oil pressure was low. En route to the airport, the engine quit. A forced landing was made on a road where during the landing the airplane collided with telephone wires and subsequently the terrain. Inspection of the engine revealed that the governor idler gear stud that holds the idler gear in place was missing. The gear was floating freely in a small cavity and wearing a hole through the housing on the propeller governor. Metal was found in the oil pan and in the oil filter. The engine overhaul was completed 3 operating hours prior to the accident.
