Probable cause:
The exact cause of the accident could not be determined with certainty. However, it is believed that the loss of control was the consequence of the failure of the artificial horizontal. Also, it is possible that cargo shifted during the right turn, modifying the CofG and causing the aircraft to be uncontrollable.

Circumstances:
After takeoff from Krasnoyarsk-Cheremshanka Airport, while climbing to an altitude of 2,040 meters at a speed of 480 km/h, the right engine (engine n°3) suffered an uncontained failure and caught fire. The crew declared an emergency and was cleared to return for an emergency landing. On final approach, the aircraft banked right then nosed down and crashed at a speed of 425 km/h 3,200 meters short of runway threshold and disintegrated on impact, some 11 seconds prior to landing. A passenger was seriously injured while 110 other occupants were killed.
Probable cause:
It was determined that the failure of the right engine was the consequence of a fatigue failure of the first stage low pressure compressor disk due to metallurgical and manufacture defect. A fire erupted in the right engine and quickly spread to the right wing and the engine n°2 because the crew forgot to close the fuel valve.
