Accident Details
An aircraft departed Chita on a flight to Tungokochen with an intermediate stop in Usugli. Three crew members were aboard, conducting a forest survey mission. The takeoff roll in Usugli was long, and the airplane became airborne after traveling 400 meters.
During the initial climb, at a height of 100 meters, the pilot initiated a left turn. The aircraft then stalled and crashed in a swamp. All three occupants sustained injuries, and the aircraft was destroyed.
Probable Cause
The investigation determined that the total weight of the aircraft was 150 to 200 kilograms above the maximum takeoff weight (MTOW). Additionally, the crew failed to abandon the departure procedure when the takeoff roll was abnormally long.
