Chronology of events:

Manager, which controls the setting of the aircraft, violating the requirements of GMP and GA-85 "Technology works manager Bugulma airport landing" did not inform the crew of the aircraft exceeded the boundary tolerances on the final approach, landing and are not banned does not have to go to the second round. With the removal of 3500 m the crew was able to bring the aircraft into the zone of permissible deviation of course and altitude with almost constant Vred = 220 km / h. With listantsii 2600 m beginning to happen unbalance the aircraft in pitch, which was accompanied by increased costs of the elevator, which is probably associated with the de-icing of aircraft. From a distance m 1700 aircraft became evade continuously to the right of the final course and distance 1400 m gone beyond the limits of permissible deviations of the exchange rate with the care at the same time under the glide path. The vertical descent rate achieved thus 7 m / s.

For 34 seconds before the incident controller gave the crew team on a missed approach. After 5 seconds after the alarm about the CDF flight commander gave the order to go to the second round, which was made from a height of 60 m increase in motor mode without retracting the flaps before takeoff. This caused an increase in the negative angle of attack of the horizontal tail to the critical value. Belated action to retain the wheel and a sharp piloted under icy stabilizer caused throw the elevator to the end position, which triggered mode dive, a significant decrease in vertical acceleration is less than one, a sharp lowering of the nose and curvature of the flight path of the aircraft down, that is, to "dive "aircraft, in which the wheel returns to its original position will require great effort. Acute shortage of time and height of the small crew was not given the possibility to withdraw from the "dive" plane. Plane in 05: 02: 00 802 m at a distance after the end of the strip and in 598 meters to the right of the axis fell to the ground at a speed of 260 km / h with a pitch angle 75-80 degrees with engines operating at takeoff and completely destroyed. There was no fire.

Actual weather was: visibility polose1000 m height m 80 8 octanes, wind 6 m / s, 260 degree, haze, temperature -2 ° C. In 04: 58 passed storm warning - haze 8 80 octanes m, 1000 m ,. This message has not been sent to the crew. Weather conditions at the time of the approach satisfies the conditions for falling out of frost, which means that severe icing in precipitation and clouds. The most likely icing could be at the entrance to Clear the upper limit of approximately 1000 m and up to cloud base 80 m.
