Accident Overview
Shortly after takeoff from Thubun Lake, while climbing, the airplane lost altitude, crashed, and came to rest upside down. The pilot sustained injuries, and the aircraft was damaged beyond repair.
Investigation Findings
The official investigation determined that the pilot failed to prepare the flight according to published procedures. Specifically, the pilot positioned the fuel selector to an empty tank. In such conditions, the engine stopped shortly after rotation, leading to the loss of height and subsequent crash.
Sequence of Events
The accident occurred during the initial climb phase after departure. The airplane, having just become airborne, began to descend inexplicably. The loss of engine power at a critical phase of flight prevented the pilot from maintaining altitude, resulting in a collision with terrain and the aircraft flipping over.
Probable Cause
It was determined that the pilot failed to prepare the flight according to published procedures and positioned the fuel selector on an empty tank. In such conditions, the engine stopped shortly after rotation.
