What happened
A cargo operation traveling from Polyarny Airport toward Olenek encountered severe meteorological challenges during its flight. As the aircraft progressed, the crew encountered deteriorating weather characterized by low cloud ceilings, mist, and active icing conditions.
During the flight, the aircraft experienced a loss of power in one of its engines. In response to the mechanical failure and the worsening visibility, the crew initiated a return to the departure point at Polyarny. However, the loss of engine performance made it impossible to sustain a safe flight altitude. The pilot attempted an emergency descent, which resulted in the aircraft crash-landing in a region of rough terrain.
Findings
The incident resulted in three injuries among the occupants, though no fatalities were reported. The aircraft sustained damage that rendered it a total loss. The primary factor contributing to the emergency was the loss of engine power while operating in icing and low-visibility conditions.
