Circumstances:
According to the pilot, during cruise flight the engine began to run rough and lose power. He heard a loud metallic sound; the engine vibrated violently and then lost power. He performed a forced landing to a farm field, and the airplane nosed over in the soft terrain, resulting in substantial damage to the wings. A postaccident inspection revealed that the crankshaft would not rotate. An internal inspection of the cylinders and spark plugs did not reveal a reason for the power loss. The oil system was examined and there were large amounts of metal particles in the oil. Due to a lack of suitable equipment and facilities, further disassembly of the engine was not attempted.
Probable cause:
A loss of engine power due to internal failure.
