Circumstances:
On a flight from Nazimovo to Yeniseysk, the engine lost power due to bad quality of the used B-91/115 fuel. While the aircraft was flying at a height of some 150 metres above the ground, the crew opted for a forced landing in a forest located 40 km northwest of Yeniseysk. The aircraft collided with trees, crashed, caught fire and burnt out. A passenger and a pilot were killed while all 12 other occupants were injured, three of them seriously.
Probable cause:
Engine failure caused by a poor quality fuel.

Circumstances:
Three minutes after takeoff from Udskoye Airport, while climbing to a height of 100 meters, the pilot-in-command initiated a left turn when the airplane banked left then lost height and crashed in flames in a wooded area located 200 meters from a house. The aircraft was destroyed and all nine occupants were killed.
Probable cause:
The loss of control was the consequence of a sharp turn at an altitude less than 100 meters with gusting winds at 15 meters per second while the pilot was intoxicated. Investigations reported that the crew failed to prepare the flight according to the published procedures and that they precipitated the departure. An unauthorized passenger boarded and the crew failed to contact ground after liftoff.

Following the collision, both aircraft dove into the ground and crashed in a field located few km from the airport. All 27 occupants in both aircraft were killed.
Probable cause:
It was reported that a radar failed and ATC was unable to determine the exact position of both aircraft. Poor visibility due to marginal weather conditions was considered as a contributing factor.

The aircraft was totally destroyed by impact forces and debris were found on an area of 550 meters long and 80 meters wide. None of the 174 survived the crash. Among the passengers were 128 Russians, 38 Chileans, six Algerians, one East-German and one Australian. Up to date, this was the worse plane crash in History.
Probable cause:
The exact cause of the accident could not be determined with certainty. However, the assumption that the loss of control was the consequence of a technical problem with the elevator control system or the longitudinal control system wass not ruled out.

Some debris and dead bodies were found in the evening while the main wreckage sank by a depth of about 1,000 meters. None of the 109 occupants survived the crash and the wreckage was not recovered.
Probable cause:
Due to lack of evidences, the exact cause of the accident could not be determined with certainty. However, the assumption that the loss of control may have been caused by the failure of an instrument or an in-flight collision with migratory birds was not ruled out.

Circumstances:
The four engine airplane departed Karaganda Airport at 0831LT on a schedule service (SU558) to Moscow-Domodedovo. En route, while cruising at an altitude of 7,200 meters, the crew informed ATC about smoke in the cabin and cockpit and request to divert to Magnitogorsk Airport for an emergency landing. During the descent, at a speed of 370 km/h, in a flat attitude, gears and flaps retracted, the airplane struck the ground and crashed in flames in an open field located 23 km north of the airport. The aircraft was totally destroyed and all 102 occupants were killed.
Probable cause:
The cause of the disaster was the intensive development of a fire that broke out in the rear cargo hold, which led to a complete or partial loss of the crew's working capacity, the impossibility of visual flight and observation of instruments due to smoke in the cockpit and the exclusion of the possibility of a successful flight outcome. The most likely cause of the fire was the triggering of pyrotechnic devices, the ignition or self-ignition of flammable materials in the baggage of passengers whose traces were found in the remains of baggage.
