Accident
A cargo flight originating from Fairbanks was on final approach to Sagwon when the crew encountered poor weather conditions, including low clouds. While descending to an altitude of 175 feet, the aircraft struck the ground in an approximately 30° bank near a level pitch attitude and crashed. Both crew members sustained fatal injuries.
Probable Cause
The official investigation determined the probable cause to be improper IFR operation by the crew, which resulted in an uncontrolled collision with the ground. Contributing factors included a low ceiling and weather conditions that were considerably worse than forecast.
