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.

Circumstances:

The airplane was completing a cargo flight to Yeniseysk, carrying six crew members, a passenger in charge of the cargo and a load of 1,042 kilos of sausages, 1,200 kilos of meat, 550 kilos of haring and 2,152 kilos of oranges. The approach was initiated by night and poor weather conditions with limited visibility due to snow falls. On final, approach lights were turned on when the crew saw trees. The captain decided to gain height and increased engine power when the airplane struck trees located on the top of a hill, stalled and crashed in a wooded area located 105 meters to the right of the inner marker and 1,140 meters from the runway threshold. Two crew members were killed while five other occupants were injured. The aircraft was destroyed.

Probable cause:

It was determined that the navigator, the radio operator and the mechanic were intoxicated at the time of the accident. The flight engineer and the navigator failed to follow the approach procedures, probably due to the influence of alcohol. The navigator failed to maintain the calculated rate of descent and altitude, failed to report about what has been achieved in terms of visibility CDF earth landmarks. The mechanic failed to report the airspeed and the altitude in reference of the radio altimeter until 60 meters above the ground. Poor crew coordination and the fact that the captain failed to initiate a go-around procedure were considered as contributing factors.

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:

Following an uneventful flight from Irkutsk-Magan Airport, the crew started the descent to Zheleznogorsk-Ilimskiy Airport in relative good weather conditions with a horizontal visibility of 20 km. On final, at an altitude of 400 meters, the three engine airplane collided with a Soviet Air Force Mil Mi-8 helicopter registered CCCP-22268. Inbound from Bratsk, the helicopter was completing a training mission with seven people on board. Following the collision, both aircraft dove into the ground and crashed in a wooded and hilly terrain located about 11 km from the airport, bursting into flames. All 40 occupants in both aircraft were killed.

Probable cause:

It was determined that the collision was the consequence of a poor ATC surveillance, causing both aircraft to initiate an approach without ensuring that they each maintained a minimum separation in accordance with published procedures. This situation allowed the helicopter to cut off the approach path of the aircraft. The lack of radio communications between the three parties concerned remained a contributing factor.

Circumstances:

The airplane was engaged in a geological support mission. While approaching Yessey Airstrip, during a fourth turn, the pilot-in-command elected to correct the roll but his reaction increased the roll to an angle of 45°. The airplane lost height and crashed on the icy Yessey lake about 5 km from the village. There were no casualties.

Probable cause:

Inappropriate roll correction from the pilot on approach caused the aircraft to bank excessively, to lose height and to crash.
