Probable cause

A total loss of engine power for undetermined reasons.

NTSB narrative

While making a crosswind turn in a non-registered airplane, the engine sustained a total loss of power. The pilot checked to ensure the throttle setting was at maximum power and that the ignition switch was ON, but the engine did not restart. He initiated a forced landing to an off-airport site where the fuselage and both wings were substantially damaged. The pilot had previously conducted significant maintenance on the fuel system; however, all the maintained components were found to be in functional condition. Components vital to the investigation were removed and unavailable for examination, which precluded a complete and through investigation of the fuel system. Postaccident examination of the airplane and engine revealed no mechanical malfunctions or failures that would have precluded normal operation. Environmental conditions at the time of the accident were not conducive to carburetor icing.
