Event
Two takeoff attempts were aborted for unknown reasons. During the third takeoff roll and initial climb, the pilot informed ground personnel about an engine failure and elected to return for an emergency landing. While completing a last turn to the right to reach the approach path, the aircraft banked right, stalled, and crashed in flames in a wooded area located two kilometers short of the runway threshold. The aircraft was destroyed upon impact, and all seven occupants were killed.
Investigation
Investigators analyzed the VHF radio recordings but were unable to determine the cause of the steep right turn that occurred during the initial climb. The steep turn was confirmed by eyewitnesses and by examination of the debris at the point of impact.
Probable Cause
The official probable cause states that the VHF radio analysis failed to determine the cause of the steep turn to the right during the initial climb, a turn confirmed by eyewitnesses and debris examination. It is believed that the aircraft banked right down to an angle of 90° before impacting terrain, most probably following an engine failure.
