Probable cause

The pilot's failure to attain the proper touchdown point. Factors were: a power failure due to a sheared accessory drive gear, excessive airspeed and altitude, and a soft field.

Analysis

The engine lost power when the airplane was at an altitude of 10,000 feet MSL. The pilot's attempts to restore power were unsuccessful. He attempted to make a forced landing on a farm airstrip, but his altitude and airspeed were excessive and he overshot. The pilot landed in an adjacent soft field and the airplane nosed over. The pilot later reported that the accessory drive gear had sheared.
