The pilot reported that he heard a 'loud bangâ from the engine during cruise flight, which was followed by 'severe vibration.â The pilot moved the throttle to idle, but the vibration got worse. The pilot then applied full throttle, and the engine seemed to run smoothly. However, the engine subsequently began to lose power, and the airplane was unable to maintain altitude. About 0.75 miles from the runway, the engine completely lost power, and the pilot executed a forced landing to a cornfield, during which the airplane nosed over which resulted in substantial damage to the upper left wing and struts. Partial disassembly of the engine revealed that the master rod, that connects the piston in one cylinder to the crankshaft, had failed.
Probable Cause: The failure of the engine master rod, resulting in a total loss of engine power and a forced landing.
