NTSB investigators may have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The certificated airline transport pilot was conducting an aerial caribou survey, aided by radio-equipped tracking collars. He began to receive a radio signal and began a descent over the flat, featureless, snow-covered terrain, and was soon able to make visual contact with a herd of caribou. The pilot said, in part: "...as we passed over the top of the herd I made a turn to the right. The wings had just rolled level, and the airplane just came to a stop in the snow." He added that during the turn, he lost visual contact with the snow-covered terrain, and collided with the ground at a shallow angle. He reported that flat light conditions made it very difficult to discern any topographical features in the surrounding area.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's failure to maintain altitude/clearance while maneuvering. Factors associated with the accident were flat light conditions, and snow-covered terrain.
