What happened
During a regional flight departing from the Yamal peninsula, the aircraft experienced a mechanical malfunction involving the loss of power from one of its engines. While traveling enroute, the crew was forced to perform an emergency descent into the tundra region located near Yar-Sale.
The impact during the crash landing resulted in extensive structural damage to the airframe. Specifically, the landing gear, the propeller, and the lower wings were all broken during the event. Despite the severity of the damage, which rendered the aircraft a total loss, there were no fatalities or injuries reported among those on board.
Findings
Investigations into the incident identified that the primary factor was an engine failure in flight, though the specific underlying reason for the mechanical malfunction remains undetermined.
