What happened
During a nighttime descent toward Tura Airport, the crew of the aircraft was operating under marginal weather conditions characterized by light snow and visibility of approximately 3,500 meters. After receiving clearance for landing, the flight proceeded with its approach. While traveling at a speed of 160 km/h, the pilot executed a right-hand turn. During this maneuver, the aircraft entered a descent with a 10-degree nose-down attitude and a 40-degree bank angle, leading to an impact with trees in a snow-covered forest. The crash site was located roughly 9.6 km southeast of the airport near the Bazhenov River.
The wreckage was discovered the following day. There were nine fatalities among the occupants of the aircraft, which included several high-ranking regional officials.
Findings
Investigations into the accident determined that the primary cause was controlled flight into terrain resulting from an incorrect altimeter setting. The presence of reduced visibility due to snow and limited sightlines also served as a contributing factor to the impact.
