The air traffic controller instructed to follow the established corridor Troitskoe. Mild stratocumulus clouds were present along the designated route. At an altitude of 4,000 meters the aircraft ceased communications with Khabarovsk air traffic control, proceeding along the designated route. At 21:39 local time the pilot switched air traffic controllers, and after receiving permission started increasing altitude to 8,000 meters. The aircraft started experiencing control difficulties at 4,500 meters, approximately 1 minute and 37 seconds after the last communications with air traffic control. The pilots expressed dismay at the sharp roll of the wings; the aircraft disappeared from radar 36 seconds later, crashing into a swamp. All passengers and crew were killed in the crash.Cause
No official cause of the accident was discovered, but it was determined that the autopilot feature could have improved some aspects of control. The commission responsible for investigating the accident concluded that:It is worth noting that the civil commission was not allowed to review materials falling under the classification "Military Secret". This has led to some theories that the aircraft could have been accidentally shot down by a surface-to-air missile launched from the Litovko military base.References
