What happened
During the departure phase from Thunder Bay, an aircraft encountered critical power loss while attempting to climb. The right engine experienced a failure, followed by a loss of power in the left engine. As the aircraft lost altitude, it descended into a prairie region where it struck various obstacles before coming to a final rest.
The impact resulted in the total destruction of the airframe. Both members of the flight crew sustained injuries during the accident sequence.
Findings
Investigations into the dual engine failure determined that the primary cause was water contamination within the fuel supply, which led to the simultaneous loss of power across both engines during the climb.
