Probable cause

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.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that the engine ran fine during the run-up inspection and takeoff, and the airplane was within weight and balance limitations. The departure runway had an upslope, there was rising terrain in the departure corridor, and witnesses reported a light tailwind at the time of departure. Shortly after the airplane lifted from the runway, it 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.
