Circumstances:
The crew was completing a flight from Stuttgart, Germany, to Toronto, with intermediate stops in Shannon, Keflavik and Frobisher Bay. While descending to Frobisher Bay, the crew informed ATC about his position about 50 km southeast of the destination airport with a fuel reserve for about 15 minutes of flight. Shortly later, the airplane struck the slope of a mountain located 106 km southeast of Frobisher Bay, near Newton Fiord. The wreckage was found few hours later and all nine occupants were killed.
Probable cause:
It was determined that the radio beacon located near Frobisher Bay Airport failed shortly after the crew was cleared to start the approach. This caused the aircraft to deviate from the approach track and to descent to an insufficient altitude, resulting in a controlled flight into terrain. Lack of visibility due to the night was a contributing factor.

Circumstances:
The aircraft was engaged in a local spraying mission, carrying a crew of three and a load of 3,666 gallons of insecticides. After takeoff from runway 23, while in initial climb, the airplane entered a flat attitude then descended until it struck trees and crashed in flames about 3 km southwest of the airport. The aircraft was totally destroyed by a post crash fire and all three crew members were killed.
Probable cause:
Investigations determined that the flaps were retracted at the time of the accident while the aircraft was flying at a relative low speed during initial climb. It is believed that this was likely a result of a premature retraction of the flaps on part of the flying crew below the minimum altitude of 500 feet, resulting in a loss of altitude.
