Chronology of events:

The crew was allowed to board the SSP landing and data on actual weather, which provided for horizontal visibility of 5300 m and a lower cloud boundary at 400 meters. But in the approach to landing, deterioration of visibility took place due to the beginning of the snow charge, in which the aircraft landed on the pre-landing line. The aircraft at a distance of about 3300 m to the strip the centerline of the lane crossed and started to move to the left. In 195 on the left and in 950 m to the end of the strip there were helipads, their brightness of the lights was much higher than that of the strip lights. In conditions of poor visibility and night due to heavy heavy snowfall, the crew mistakenly took helicopter platforms for the working area. At an altitude of approximately 120 m, located at a distance of 2840 m from the strip (1800 m to helicopter landing sites), the aircraft left to the left of the landing course line at 60 m and was located lower than the glide path at 30 m. The crew in the further decline, taking for Ipopoly lights Helicopter parking, performed an S-shaped maneuver and aligned the flight rate with respect to the longitudinal axis of the parking. With an undershoot to the end of the strip 950 m and to the left of the axis at 159 m, the crew at the speed of 190 km / h made a landing on helicopter platforms. When running, the crew noticed obstacles and to avoid a collision, tried to turn the plane to the right, but a short distance and a huge speed of movement made it impossible to avoid a collision. The plane collided consistently with three Mi-8T helicopters (RA22313, RA25144, RA25939, all airlines Tyumeniaviatrans) and crashed. The first two helicopters were destroyed, the third tail boom lost. In Yak-40, the bow is destroyed and the left wing plane is torn off. Under snowfall conditions, the lower edge of the clouds was 200 m, the actual visibility was 1400 m.

The details:

The findings, which investigated plane crash

The cause of the catastrophe was a combination of the following factors:

1) lack of crew information about the deterioration of visibility is less than the minimum airport during landing;

2) the continuation of the approach when you change the weather is less than the minimum visibility for the aerodrome;

3) including parking light helicopters exceeds much power strip lights, low visibility (snow charge), which triggered the crew on his erroneous perception of the lights of the strip when it is impossible to effectively control the movement of the aircraft after passing NDB.
