Probable cause

The pilot's failure to maintain airspeed while performing an emergency landing, which led to the airplane exceeding its critical angle-of-attack and experiencing a subsequent aerodynamic stall. Contributing to the accident was a partial loss of engine power for reasons that could not be determined during postaccident examinations.

NTSB narrative

The pilot reported that he performed a preflight inspection with no anomalies noted. In addition, he performed an engine run-up, and everything was normal. During the initial climb, about 200 ft above ground level and just over the departure end of the runway, the pilot noticed that the airplane was not producing full power; witnesses corroborated that the engine lost partial power after the airplane reached the end of the runway. The pilot chose to return to the runway and performed a 180-degree turn. Once the airplane was over the runway centerline, the pilot attempted to add power; however, the engine did not respond. Witnesses reported that, as the airplane neared the runway, the pilot "flared too high" and that the airplane then "stalled," descended, and impacted the runway. A postimpact fire ensued. A postaccident examination of the engine revealed no evidence of mechanical failures or malfunctions that would have precluded normal operation. The reason for the partial loss of engine power could not be determined.
