Accident Sequence
The aircraft departed from Sverdlovsk-Koltsovo Airport for a night flight. One minute after rotation, while climbing at an altitude of approximately 150 meters, one engine failed. For reasons that remain unknown, the flight crew was unable to shut down the failed engine and feather its propeller.
The resulting drag caused the airplane to bank to the right. The crew lost control, and the aircraft entered an uncontrolled descent. It struck the ground at a speed of 440 km/h in a field located 2,900 meters past the departure end of the runway.
Aftermath
The impact destroyed the aircraft, and debris was scattered over a distance of 320 meters. None of the 107 people on board survived.
Probable Cause
According to the official investigation, the exact cause of the engine failure could not be determined. However, it was noted that the engine failure occurred at a critical stage of flight, which was considered a contributing factor.
