Probable cause
The loss of engine power during initial climb for undetermined reasons.
NTSB analysis
The pilot reported that he performed a preflight examination and pretakeoff engine run-up of the airplane and no anomalies were detected. He reported that the takeoff was normal until just after liftoff when the airplane's engine lost power but did not quit completely. The pilot advanced the throttle, but the engine did not respond. The airplane struck a fence at the end of the grass runway, settled into the adjacent agricultural field, and nosed over. Examination of the airplane subsequent to the accident failed to reveal a reason for the partial loss of engine power.
