Accident Details
An Antonov An-2, registered RA-33589, was engaged in a local skydiving operation with one pilot and nine skydivers aboard. Shortly after takeoff from runway 31, while climbing to approximately 80 meters, the engine lost power. The pilot initiated a left turn to return to the airport. During the turn, the aircraft banked to 60 degrees, stalled, and impacted a snow-covered field near a forest. The crash triggered a fire that destroyed the aircraft. Nine occupants escaped with injuries; one passenger was killed.
Probable Cause
According to the official investigation, the accident was most probably caused by the aircraft entering beyond stall angle of attack during a dynamic turn for an emergency landing with reverse runway heading, following engine failure after takeoff at low altitude. The engine failure resulted from high-temperature damage and destruction of cylinder-piston group parts due to inadequate technical operation and the use of motor gasoline in the fuel system that did not meet the quality requirements for preferred AI-95 gasoline as per applicable orders and engineering solutions. A contributing factor was the pilot's partial loss of control skills for the An-2. The pilot's decision to perform a straight-ahead landing most likely did not reduce the severity of the accident consequences.
