What happened
During a flight through snow showers at an altitude of approximately 1,800 meters, the crew notified air traffic control that a fire had ignited in the right engine. Shortly after this initial report, the crew communicated that they were unsuccessful in suppressing the flames and decided to divert the aircraft toward Pokrovsk.
During the descent phase, the pilot attempted an emergency landing. During this maneuver, the aircraft type struck treetops before crashing into a snow-covered forest located roughly 35 km from Pokrovsk. The impact resulted in a post-crash fire. Of the people on board, 15 fatalities were recorded, while 5 passengers were successfully rescued from the wreckage.
Findings
Investigations into the accident determined that the primary factor was a rupture of a fuel line, which triggered the fire in the right engine.
