Accident Details
Shortly after takeoff from Eucott Bay, British Columbia, the pilot began a climb to about 300 feet. The pilot then initiated a left turn to perform a 180-degree circuit, a standard procedure for leaving the valley. During the turn, despite the addition of power and a continuing climb, the aircraft descended to the left, stalled, and crashed into a wooded area located 450 metres west of the departure point. The aircraft burst into flames upon impact. All five occupants were killed.
Investigation
The investigation into the accident examined the circumstances of the flight. The aircraft had just departed and was executing a routine maneuver when the loss of control occurred. The terrain and weather conditions in the area were considered as potential factors.
Probable Cause
The official probable cause stated: "The exact cause of the accident could not be determined. However, the assumption that the loss of control was caused by downdrafts was not ruled out."
