What happened
A cargo flight transporting construction materials from Thunder Bay to Fort Severn ended in a fatal accident during the final approach phase. While navigating through dense fog, the crew of the aircraft struck the bank of the Severn River.
Following the initial impact with the riverbank, the plane bounced back into the air and collided with the roof of an Anglican church. The sequence of events concluded when the aircraft crashed into a graveyard, located approximately 3 km from the threshold of runway 15. The impact resulted in the total destruction of the aircraft and three fatalities.
Findings
Investigations into the accident determined that visibility was severely restricted by heavy fog at the time of the incident. The primary factor contributing to the crash was that the crew descended below a safe altitude, leading to the impact with the terrain.
