Circumstances:
While in cruising altitude on the leg from Irkutsk to Chita, a hijacker went into the cockpit and ordered the crew to fly to China. Negotiations between the crew and the hijacker were unfruitful and after few minutes, a member of the militia shot the hijacker. Before dying, the hijacker was able to fire a system connected to several grenades attached to his belt. A huge detonation occurred in the cabin, causing the aircraft to disintegrate in the air. From an altitude of 6,500 meters, the airplane entered a dive and crashed in the taiga about 97 km west of Chita. Debris were found on a wide area and none of the 81 occupants survived the crash. Soviet Authorities later reported that the hijacker was a mental imbalance and explained his gesture by their recent refusal to grant him a job position within the diplomatic corps.
Probable cause:
Explosion of a 'bomb' after being hijacked.
