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.

Circumstances:
While cruising by night at an altitude of 7,800 meters in good weather conditions, the pilot-in-command initiated a turn to the left when control was lost. The airplane entered a dive and spiraled to the ground. At an altitude of 5,000 meters, some elements of the upper wing surface and the stabilisers detached and the airplane disintegrated in the air before crashing in a steppe located about 84 km south of Semipalatinsk. Wings and stabilisers parts were found at a distance of some 3.5 km from the crash site. All 63 occupants have been killed.
Probable cause:
The exact cause of the accident could not be determined. The assumption that the aircraft collided with an object was not ruled out. It is believed the crew may have start an emergency descent but the reason of this manoeuvre could not be established. FDR could not be read properly as it was seriously damaged in the crash.
