Incident
The flight originated from Kurun-Uryakh with a planned stop at Nelkan before proceeding to Udskoye in support of an expedition. While on the leg from Nelkan to Udskoye, the aircraft encountered weather conditions that were below the required minima for approach, characterized by low clouds and fog. The crew did not abort the approach and failed to return to the previous point. Instead, they continued the flight but deviated from the prescribed flight path. The aircraft strayed 14 kilometers to the left of the intended course and struck a wooded slope on a hill located 16 kilometers southeast of Udskoye. The impact occurred at an elevation of 300 meters, which was 150 meters above the airport's elevation. The collision and subsequent post-crash fire destroyed the aircraft.
Casualties
One crew member was killed in the accident. The other two occupants on board sustained serious injuries. The wreckage and the survivors were located by search parties one day after the crash.
Probable Cause
According to official findings, the accident was caused by the crew's decision to continue the flight in below-minima weather conditions and their failure to return, which resulted in the aircraft striking obstacles and crashing.
