What happened
During a geological expedition along the Bolshaya Osinovaya River, an aircraft carrying a total of eight people—consisting of five scientists and three crew members—was involved in an accident. The flight departed from Tanyurer at a very low altitude of approximately 80 meters.
Shortly after the departure phase, the pilot-in-command executed a sudden left-hand turn. This maneuver caused the aircraft type to enter a stall, resulting in a crash. While the impact led to the total destruction of the plane, all eight occupants were successfully rescued from the wreckage. The survivors sustained only minor injuries during the event.
Findings
Official investigations concluded that the accident was the result of improper piloting techniques. Specifically, the captain performed an excessively sharp turn while flying at a low altitude, which directly led to the loss of control and subsequent stall.
