What happened
During an operation to relocate equipment from a remote outpost threatened by forest fires, a DHC-3 aircraft experienced a loss of altitude shortly after takeoff. The flight was departing from the Tadoule Lake (Lac Brochet, MB) area, heading west into light winds of approximately 5 to 8 knots. The aircraft was carrying a significant load, including two 45-gallon drums of gasoline, a propane cylinder, battery chargers, and various other supplies. The aircraft was operating near its maximum gross weight at the time of the incident.
As the aircraft climbed, it encountered a sudden change in wind direction. While the initial takeoff involved a headwind, the aircraft transitioned into an area of tailwind. This windshift likely created a downdraft situation. Despite the application of full engine power, the aircraft began to descend. The plane settled into the trees with very little forward momentum and a nearly level wing attitude. Following the impact, the aircraft caught fire. The pilot and two passengers managed to exit the wreckage with minor injuries.
Findings
- The aircraft was operating at a weight near its maximum allowable limit.
- A sudden windshift from a headwind to a tailwind occurred during the initial climb.
- The presence of a nearby forest fire may have influenced local wind conditions.
- A second aircraft, a Cessna 185, was in the vicinity and witnessed the event; its pilot landed to assist the survivors.
