NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.
Prior to takeoff, the pilot obtained a weather briefing from the flight service station. Witnesses, who were located on the airport, reported that shortly after takeoff, the airplane was 150 feet agl and flying runway heading. The right wing was low, landing gear extended, and the nose in a climb attitude, but the airplane was not climbing. As the airplane approached the end of the runway, the airplane lost altitude and "was still mushing along." The right wing then rolled to an almost vertical attitude, the nose dropped, the airplane rolled to the left and impacted terrain. One witness stated there were no mechanical problems with the airplane and the engine sounded normal. The airplane was destroyed by postimpact fire. Examination of the airframe and engine revealed no anomalies that would have precluded normal operation. The airplane was 126.2 lbs over gross weight at the time of the accident. Witnesses reported gusty wind conditions, thunderstorms in the area, and no precipitation. Weather data revealed environmental conditions that supported dry microburst activity at the time of the accident.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: the pilot's improper preflight planning, his attempted flight into adverse weather conditions, and the stall resulting in the loss of control and subsequent crash. Factors contributing to the accident were the pilot's inadequate evaluation of the weather conditions, the airplane exceeding its gross weight limitations, and the dry microburst from thunderstorms located near the airport.
