Accident
During a night approach to Sverdlovsk-Koltsovo Airport under foggy conditions, the crew deviated below the glide path due to pilot error. The aircraft struck tree tops approximately 900 meters behind the outer marker and 160 meters to the right of the extended runway centerline. It then crashed in a meadow 220 meters further on, which was 3,100 meters from the airfield perimeter. Two crew members and two passengers were killed, while 23 other occupants sustained injuries, one of them serious.
Probable Cause
According to the official findings, the probable cause was a wrong approach configuration, poor discipline, and inappropriate decisions on the part of the crew, who decided to continue the approach in poor visibility.
