The flight was chartered by a local engineering company to transport equipment to Kugluktuk and return with empty fuel barrels. On the return trip, the pilot was to overfly and inspect the abandoned airstrip at Port Radium on Great Bear Lake, from which he planned to operate in the next few days. The flight arrived in Kugluktuk at 13:18, unloaded the cargo, loaded empty fuel barrels, and refuelled. The flight departed Kugluktuk at 14:24 for Port Radium. Using GPS navigation the pilots flew to Port Radium and initiated a descent for the airstrip. The plane descended until it hit treetops. The wings were torn off the fuselage and the fuselage contacted up-sloping rocky terrain. The aircraft bounced and tumbled up the 12-degree slope and came to rest at the top of a steep slope of snow and ice, inverted.

Probable Cause:

FINDINGS AS TO CAUSES AND CONTRIBUTING FACTORS: "1. Although the pilot and the aircraft were certified for instrument flight, the pilot apparently continued to fly in accordance with visual flight rules after encountering marginal weather conditions and reduced visibility.; 2. For undetermined reasons, the pilot descended below the elevation of the terrain surrounding the airstrip, resulting in a controlled-flight-into-terrain accident."
