Circumstances:
The aircraft departed Chita on a flight to Tungokochen with an intermediate stop in Usugli, carrying three crew members who were engaged in a forest survey mission. The takeoff roll in Usugli was long and the airplane took off after a distance of 400 meters. During initial climb, at a height of 100 meters, the pilot initiated a left turn when the aircraft stalled and crashed in a swamp. All three occupants were injured and the aircraft was destroyed.
Probable cause:
It was determined that the total weight of the aircraft was 150-200 kilos above MTOW. The crew failed to abandon the departure procedure when the takeoff roll was abnormally long.
