Narrative:
The pilot took off from runway 09 at Tuktoyaktuk at 17:06:34, and had turned the aircraft to a southerly direction when the right engine lost all power. He decided to return to the airport. While manoeuvring back to the airport, the aircraft struck an ice-covered lake in a steep, 65 degrees nose-down attitude. The engines and front of the aircraft penetrated the approximately two-foot-thick layer of ice. The remainder of the fuselage, wings, and empennage remained on the ice surface.

Probable Cause:

CAUSES: "A magneto impulse coupling, worn beyond the prescribed limits, resulted in the failure of the right engine. Following the engine failure, the pilot mistrimmed the rudder and was unable to maintain control of the aircraft."
