Event WPR11CA196
Aircraft involved
Probable cause & findings
The pilot's inadequate evaluation of the wind conditions at takeoff and failure to maintain an adequate airspeed, which resulted in a stall and collision with terrain during the initial climb.
Factual narrative
The pilot reported that the engine ran fine during run up and takeoff, and the airplane was within weight and balance limitations. The departure runway had an upslope, and there was rising terrain in the departure corridor. Witnesses reported a light tail wind at the time of departure. The airplane got airborne, but began to settle. The pilot pitched the nose up to try and fly over the terrain at the end of the runway, but the airplane stalled into the terrain about 500 feet past the departure end. The airplane nosed over inverted and the airframe and wings sustained substantial damage.
