Ust-Tsylma

After takeoff from Novy Bor Airfield, while climbing to a height of about 10 metres, the aircraft nosed up. The pilot reduced the engine power when the aircraft stalled and crashed on the runway about 150 metres from its end. All 14 occupants evacuated safely while the aircraft was damaged beyond repair. It was reported that the CofG was well beyond the aft limit.

On a positioning flight from Kharyaga to Ust-Tsilma, the engine failed shortly after takeoff. The crew elected to return to the airport but altitude and speed were not sufficient. After 'hopping' over a telegraph line, the left wing hit the ground and the aircraft impacted the tundra 400 metres short of runway. Both pilots and both passengers (aircraft mechanics) were killed. A day prior to the accident, the crew completed flight SU917 from Ust-Tsilma to Kharyanga via Novy Bor but the flight was interrupted in Kharyaga due to engine problems and two technicians were dispatched at Kharyaga Airport.

The airplane departed Ust-Tsylma on a flight to Ukhta, carrying four passengers and a pilot who were in charge to collect election materials. In unknown circumstances, the airplane crashed 40 km north of Ukhta, coming to rest broken in two. All five occupants were uninjured.

The single engine airplane was approaching Leshukonskoye on a flight from Ust-Tsylma when it crashed in unknown circumstances 18 km north of Leshukonskoye. All five occupants were uninjured while the aircraft was destroyed.
