[1] The visibility at Leshukonskoye airport was 5 km, with drizzle, a wind speed of 3 m/s and air temperature 0 °C (32 °F).

Sixteen kilometres away from Leshukonskoye airport and at an altitude of 500 m (1,600 ft), the crew put the landing gear down and set the flaps at 15 degrees.

Then the flaps were set to 38 degrees and the aircraft, piloted by captain, started to descend.

The left bank angle ultimately reached 90 degrees and the aircraft crashed 110 m to the right of the runway.

The investigation placed the responsibility for the accident on the captain Alimov, who was found to have a risky style of piloting, which violated the flight instructions.
