The airplane settled back to the ground and collided with terrain shortly after takeoff from a dirt strip under gusting tailwind conditions.

What happened

Shortly after lifting off from a dirt runway, the aircraft encountered challenging weather conditions characterized by gusting tailwinds. During this critical phase of flight, the pilot initiated the retraction of both the flaps and the landing gear. Following these actions, the airplane lost altitude and settled back onto the ground, resulting in a collision with the terrain.

The investigation

Post-acc examination revealed no evidence of mechanical failures or malfunctions that would have contributed to the accident. The pilot reported that the aircraft was operating normally prior to the incident, indicating that the event was likely due to operational factors rather than equipment failure.

Probable cause

The pilot's decision to retract the flaps and landing gear during takeoff in gusting tailwind conditions, which resulted in a loss of control and collision with the terrain.
