Primary finding
Probable cause
The pilot's failure to maintain aircraft control during initial climb, which resulted in a loss of adequate airspeed and a subsequent aerodynamic stall.
Investigator assessment
Analysis narrative
The pilot reported that he was performing a soft-field takeoff. He stated that the winds were variable at 3 knots. He lowered 10 degrees of wing flaps, applied full back pressure on the control column, and applied full engine power. The airplane became airborne, went out of ground effect, and then stalled. The airplane spun to the left, descended, and impacted the ground. The pilot reported that he had no mechanical malfunctions with the airplane. Examination of the airplane revealed structural damage to both wings and to the engine firewall.
