Circumstances:
In the morning, the crew completed two geophysical missions on behalf of the Severo-Yeniseysk expedition. In the afternoon, four passengers were illegally embarked for a fishing party on the Kotui River. In the evening, while flying back to Chirinda, the airplane suddenly lost height, struck tree tops and crashed in flames in a wooded area located on the slope of a mountain (480 meters), about 6 km southwest of Chirinda. The burned wreckage was found 132 meters below the summit and all seven occupants were killed.
Probable cause:
The exact cause of the accident could not be determined. However, it was considered that the engine probably failed in flight as the fuel quantity in both tanks was insufficient (110 liters instead of the minimum 300 liters required).
