Narrative:The engine began losing power about 1,600 feet above the ground. The airplane was unable to maintain altitude, and the pilots made a hard forced landing in rough desert terrain about 1/3-mile from the destination airport. During the subsequent borescope examination of the engine, the top surface of the number 3 piston was observed to be damaged, and the cylinder's exhaust valve head was broken off from the stem. No further inspections were performed.
Probable Cause: A loss of engine power while maneuvering due to a broken exhaust valve. Contributing to the accident was the rough terrain.
