Circumstances:

The crew was returning to Irkutsk following a cargo flight to Mirnyy. After takeoff from Kirensk Airport, while climbing to a height of some 500 meters, the airplane banked left, dove into the ground and crashed onto a wooden hut located 750 meters south of the airfield. The airplane was totally destroyed and all six crew members were killed.

Probable cause:

It was determined that both left engine lost power shortly after takeoff and progressively failed during climb. The crew elected to feather the propeller but without success. The airplane then banked to the left and crashed at an angle of 70°. Investigations were unable to determine the exact cause of the engine failure but the assumption of an electrical short-circuit or an excessive accumulation of ice in the fuel filter was not ruled out.

Circumstances:

On final approach to Irkustk-Intl Airport, the crew encountered poor weather conditions and a visibility below minima. The airplane lost height and struck approach lights located 2,450 meters short of runway 29 threshold. It then struck a hill, flew on a distance of 570 meters and eventually crashed in flames 1,880 meters short of runway. The aircraft was destroyed by impact forces and a post crash fire and two passengers were rescued while 33 other occupants were killed, among them the spouse of the Ambassador of Albania in China.

Probable cause:

It was determined that the sudden loss of altitude on final approach was the consequence of an excessive accumulation of water in the Pitot tubes, which resulted in the modification of several instrument settings and caused the aircraft to adopt an approach configuration not in accordance with the published procedures. It was reported that weather information related to Irkutsk Airport and transmitted to the crew were inaccurate and failed to reflect the truth. Also, the person in charge of the weather forecast bulletin at departure airport failed to double check the information and transmitted inaccurate data. At the time of the accident, the weather conditions at Irkutsk airport were poor and the visibility was below minima. Despite this situation, ATC at Irkutsk-Magan Airport cleared the crew to land and failed to instruct him to divert to another airport.

Circumstances:

The crew was performing a cargo flight from Irkutsk to Khabarovsk with an intermediate stop in Chita, carrying a load of brake linings and hoses for a total weight of 3,031 kilos. While approaching Chita-Kadala Airport by night, the airplane was too low, struck trees and crashed on the slope of Mt Cherskogo located 11 km short of runway threshold. The wreckage was found 170 meters below the summit and all five crew members were killed.

Probable cause:

For unknown reason, the crew started the descent prematurely and was at an insufficient altitude of 700 meters instead of 1,200 meters when the airplane struck the mountain. Due to the lack of visibility caused by night, the crew was unable to distinguish the mountain. It was also reported that ATC assistance was inappropriate, which was considered as a contributing factor.

Circumstances:

On the leg from Omsk to Irkutsk, at a distance of 160 km from the destination, the crew was informed about the deterioration of the weather conditions at Irkutsk Airport and was then diverted to Ust-Orda Airport. At this time, weather at Ust-Orda was as follow: cloud base at 250 meters, snow falls and a visibility of 3 km. On approach by night, the nose gear light was unserviceable so the captain decided to make a go around. For unknown reason, this procedure was delayed and he completed a low pass over the runway for about two km before making a turn to the left at a height of 10-15 meters when the airplane struck power cables. The aircraft stalled and crashed in flames on a hilly terrain near the airport. 46 passengers were uninjured while 19 occupants were injured. Three crew members were killed, the navigator, the radio operator and the mechanic. The aircraft was totally destroyed by a post crash fire.

Probable cause:

The decision of the captain to perform a go around was comprehensive but the very low pass (10-15 meters) above the runway was unacceptable. Investigations were able to determine that weather conditions at Irkutsk Airport were not as bad and the decision of the ATC to divert the crew to Ust-Orda was not necessary. Also, it was the first time that the pilot was flying to Ust-Orda and he did not have any knowledge about the environment at this airport, which was considered as a contributing factor.

Circumstances:

On approach to Irkutsk-Intl Airport, the crew encountered foggy conditions. Despite the visibility decreased below minima, the captain continued the approach when the left wing tip struck the ground. Out of control, the airplane nosed down, struck the ground, bounced and eventually crashed 30 meters farther. The captain and the mechanic were killed while both other crew members were seriously injured. The aircraft was destroyed. Two days later, on December 1st, the copilot died from his injuries and a day later, on December 2nd, the radio operator died as well.

Probable cause:

It was determined that the visibility suddenly dropped due to fog in the approach path and the runway threshold. Despite the situation, the captain decided to continue the approach in below-minima conditions instead of diverting to another suitable airport. Weather forecast were inaccurate and did not reflect reality, which remains a contributing factor.

After being manufactured at Frunze, the aircraft was on a delivery flight from Moscow to Irkutsk with intermediate stops at Sverdlovsk and Novosibirsk. On final approach to Irkutsk-Intl Airport, the crew encountered marginal weather conditions when the airplane hit the ground 1,315 meters short of runway, bounced, struck a fence and eventually came to rest in a prairie located 550 meters short of runway threshold. The copilot was killed while four other occupants were slightly injured. The aircraft was considered as damaged beyond repair.

Probable cause:

The flight engineer misinterpreted some instruments settings he failed to transmit to the flying crew in due time. Lack of coordination between pilots was considered as a contributing factor.
