Accident Sequence
During the takeoff roll in poor weather conditions, the number three engine failed, probably due to the ingestion of wet snow. The aircraft veered off the snow-covered runway to the right after a roll of 550 meters. It became briefly airborne with a high angle of attack until the tail struck a 70-centimeter-high mound. After losing control, the aircraft crashed in flames onto a hillside located 1,400 meters further on, near a river.
Occupants and Injuries
The accident resulted in the deaths of two passengers and a crew member. All 65 other occupants were injured. The aircraft was destroyed.
Probable Cause
According to official findings, the probable cause of the accident was the failure of engine number three during the takeoff roll due to a massive ingestion of wet snow that was thrown out from the right main gear.
