The crew was engaged in a supply mission from Thule Airbase to Dye 3 Airstrip located about 320 km east of Sondreströmfjord, Greenland. On final approach, the airplane lost height and struck the ground. On impact, the landing gear, skis, outboard fuel tanks, and the number one engine were torn off as well as 12 feet from the left wing tip and six feet of the right wing tip. The airplane came to rest in flames in the snow. Seven occupants were slightly injured while the eighth one, a Danish citizen, was killed when a propeller blade detached and penetrated the fuselage.
Probable cause (official findings): It is believed that the approach speed was too low, causing the airplane to stall during the last segment.
