Narrative:The pilot reported that, while the airplane was in level cruise flight, he heard a loud “pop,” followed by a total loss of engine power. He subsequently made a forced landing to an open, tundra-covered site. During the forced landing, the airplane nosed over, which resulted in substantial damage to the wings, fuselage, and empennage. A postaccident examination of the engine revealed a fractured exhaust valve stem on the No. 4 cylinder, which subsequently pulverized the electrodes on both sparks plugs and severely damaged the piston.
Probable Cause: The fracture and subsequent failure of the No. 4 cylinder exhaust valve during cruise flight, which resulted in a total loss of engine power.
