Circumstances:
The aircraft was completing a cargo flight from Novosibirsk to MIrny with an intermediate stop in Krasnoyarsk, carrying six passengers, seven crew members and a load of 13,380 kilos of various goods consisting of food, tobacco, clothing and footwear. Weather conditions were marginal with snow falls and icing conditions. During the takeoff roll, after a course of 2,400 metres, the pilot-in-command started the rotation at a speed of 280 km/h. After liftoff, the aircraft started to roll left and right but the crew was able to continue to climb with a rate of about 4 metres per second. During initial climb, at a height of 150 metres and at a speed of 330 km/h, the crew raised the flaps. At this time, the aircraft started to lose height, entered an uncontrolled descent, collided with trees and crashed in a wooded area located 5 km from the airport. The aircraft was totally destroyed by impact forces and a post crash fire and all 13 occupants were killed.
Probable cause:
Loss of control during initial climb after the crew raised the flaps due to the presence of severe icing conditions which impaired the controllability of the aircraft and its aerodynamic characteristics. The short distance between the aircraft and the ground did not allow the crew to expect recovery.

Circumstances:
After liftoff from runway 30 at Krasnoyarsk-Iemilianovo Airport, while climbing at a speed of 165 km/h, the aircraft encountered difficulties to gain height. It collided with 25 metres tall trees located about 1,000 metres past the runway end, rolled to the right and crashed in a wooded area, some 450 metres to the right of the extended centerline. Both pilots and a passenger were killed.
Probable cause:
A two-fold decrease in the operating mode of the starboard engine during takeoff, caused by the actuation of the limiting system of the starboard engine and caused, most likely, with the achievement of MCR limit values, or with a failure that caused the system to be connected with the issuance of a false signal to reduce the speed of the gas generator. The activation of the system according to the MCR should have been preceded by its connection to work, which could have occurred as a result of an out-of-order connection of the limiter unit with the automatic protection circuit breakers AZRGK TSEBO turned off or when taking off with the AZRGK TSEBO turned on. The manifestation of a refusal in this flight could be facilitated by shortcomings in the activities of the ATB personnel of the Abakan aviation enterprise. Also, the decision of the crew to takeoff while the total weight of the aircraft was 280 kilos above MTOW.

Circumstances:
Following an uneventful flight from Krasnoyarsk-Severny Airport, the crew started the approach to Kansk-Tsentralny but was forced to divert to Kansk-Dalniy Airport due to poor weather conditions. Nevertheless, the crew landed in below-minima weather conditions at Dalniy Airport. After touchdown, the airplane was unable to stop within the remaining distance, overran, collided with an obstacle and came to rest. There were no casualties.

Crash of a Tupolev TU-154B-2 in Norilsk: 99 killed

Circumstances:
Following an uneventful flight from Krasnoyarsk, the crew started the descent to Norilsk-Alykel Airport. At an altitude of about 600 meters and a speed of 370 km/h, the undercarriage were lowered. At a distance of 19 km from the airport, at an altitude of 500 meters and a speed of 300 km/h, flaps were deployed to an angle of 28°. At this time, the crew calculated the landing speed at 265 km/h according to flight conditions and the total weight of the aircraft. Unfortunately, this calculation was wrong and the correct speed should be 270 km/h. On short final, the airplane descended below the glide and struck the ground at a speed of 261 km/h about 470 meters short of runway threshold. It slid for about 300 meters on an icy ground before coming to rest, bursting into flames. 68 occupants were injured while 99 others were killed, among them four crew members. The aircraft was destroyed.
Probable cause:
The accident resulted from a loss of longitudinal controllability on short final due to the combination of the following factors:
- A significant reduction in the efficiency of the stabilizers after they were positioned beyond an angle of -20 °,
- An automatic reduction of power on all three engine close to idle,
- An aircraft with a forward center of gravity,
- An insufficient approach speed,
- An excessive rate of descent,
- The late recognition by the crew of an emergency situation,
- The failure of the crew to initiate a go-around procedure.

Circumstances:
At 1858LT, a technical issue occurred on the right main gear during the takeoff roll. The captain decided to continue and after rotation, during initial climb, it was not possible to raise the landing gear. The crew informed ATC about his situation and completed several circuits over the region to burn fuel. A bit more than an hour later, the crew returned to Krasnoyarsk-Severny Airport and completed an emergency landing in a grassy area located 100 meters to the right of the main runway. The airplane landed at a speed of 205 km/h. After a course of about 70 meters, the right main gear collapsed and the airplane rolled for few dozen meters before coming to rest in flames. All 53 occupants escaped the cabin but three passengers were seriously injured by fire. Two of the survivors died from their injuries two and three days later.
Probable cause:
Failure of the right main gear due to fatigue cracks in the main cylinder.

Circumstances:
Less than two minutes after takeoff from Novosibirsk-Tolmachevo Airport runway 07, while climbing by night at an altitude of 200 meters, the airplane entered clouds when the crew informed ATC about an in-flight fire. The captain was cleared to return for an emergency landing when control was lost 24 seconds later. The airplane entered a nose-down attitude and struck the ground at a speed of 335 km/h in an open field located 3 km from the airport. The aircraft disintegrated on impact and debris were scattered on a distance of 552 meters. All six occupants were killed. The airplane was carrying various prefabricated goods for a total weight of 11,278 kilos.
Probable cause:
It was determined that a fire broke out in the cargo compartment during the takeoff procedure but investigations were unable to establish the exact origin of the fire.
