Circumstances:
On the leg from Novosibirsk to Yakutsk, the hydraulic pressure on engine number 2 dropped. The captain decided to divert to Krasnoyarsk Airport for an emergency landing. The approach was completed in snow falls and during the last segment, the four engine airplane was too low and struck the ground 200 meters short of runway threshold then crashed and burned. There were no casualties but the aircraft was destroyed.
Probable cause:
The cause of the loss of hydraulic pressure on engine number 2 remains unknown. However, the decision of the crew to divert to Krasnoyarsk Airport was wrong as the weather was considered as marginal. It would be preferable to divert to Kemerovo or Bratsk Airport where the weather conditions were considered as good.

Circumstances:
While cruising at an altitude of 8,000 metres on the leg from Krasnoyarsk to Petropavlovsk-Kamchatsky, the crew sent a short inaudible message of two seconds. Shortly later, the airplane entered an uncontrolled descent and reached the vertical speed of 3,360 - 11,000 feet per minute. Once the altitude of 3,000 meters was reached on descent, the vertical speed increased from 9,850 to 24,600 feet per minute. The airplane then made a turn to the right, got inverted and partially disintegrated at an altitude of 650 meters. Debris crashed at a speed of 890 km/h in an uninhabited area located 13 km northeast of Parchum. Debris scattered on a large zone and miraculously, a passenger was found alive while 83 other occupants were killed.
Probable cause:
Investigations were unable to determine the exact cause of the accident. However, the assumption that the loss of control was caused by the failure of a fuel line was not ruled out. This may cause the fuel to leak into the engine and to ignite while in contact with high temperature equipments.

Circumstances:
The crew completed a cargo flight from Krasnoyarsk to Yeniseysk and was now returning to Krasnoyarsk on a ferry flight. The approach to Krasnoyarsk Airport was started 20 minutes after sunset. In limited visibility, the crew failed to realize he was flying at an insufficient altitude. Some 55 meters before the middle marker, the airplane struck tree tops then sank and struck successively a telegraphic pole, a wooden fence and a hangar before crashing in flames 85 meters after the middle marker. Three crew members were killed while the radio navigator was seriously injured. Three days later, the only survivor died from his injuries.
Probable cause:
The exact cause of the accident could not be determined with certainty. However, it was reported the crew apparently started the descent prematurely for unknown reason.

Circumstances:
On the leg from Krasnoyarsk to Magadan of a flight from Moscow to Magadan, the autopilot system failed while the aircraft was flying at a height of 8,000 metres by night. The aircraft banked to the left at an angle of 80-90°, entered a dive and descended at a speed of 730 km/h. Control was recovered by the crew at a height of some 4,000 metres. The crew managed to land safely at Magadan-Sokol Airport but the aircraft suffered structural damage during the dive with up to 3.8 g forces. Transferred to the Yegoryevsk technical school on 14DEC66, the aircraft was eventually struck of charge in 16FEB71 due to its poor technical condition. There were no casualties.
Probable cause:
Failure of the autopilot system in flight for undetermined reason.

Circumstances:
The aircraft departed Tashkent on a cargo flight to Yuzhno-Sakhalinsk with intermediate stops in Fergana, Novosibirsk, Krasnoyarsk and Irkutsk, carrying a load of 10,475 kilos of grapes. En route from Krasnoyarsk to Irkutsk, the crew was informed about poor weather at destination and decided to divert to Ulan Ude although that airport was not suitable for such type of aircraft. While approaching from the north in marginal weather conditions, at an altitude of 1,200 meters, the airplane struck the slope of a wooded mountain located 32 km north of the airfield. The aircraft was destroyed and all eight occupants were killed.
Probable cause:
Controlled flight into terrain resulting from a crew error who mistakenly imputed wrong QNH setting for the approach. Lack of visibility and poor flight preparation were considered as contributing factors.

Circumstances:
While cruising at an altitude of 7,500 meters, the engine number four failed. Unable to determine which of the right engine failed, the crew shot down both engines and feathered both propellers. Control was lost and the airplane banked right and entered a dive. The aircraft reached a rate of descent of 1,800 meters per minute (30 meters per second). The ailerons were sheared off and after passing through the last cloud layer at an altitude of 200 meters, the crew elected to regain control but the airplane struck the ground at a speed of 650 km/h and crashed in a snow covered field located 3,5 km southeast of Urakhcha. The aircraft disintegrated on impact and debris were found on 250 meters width and 800 meters long. Both right engines were found 600 meters away from the point of impact and elements of the ailerons were found some 12 km from the crash site. It was determined that both right engines were not running at impact while both left engines were turning at full power. The accident was not survivable.
Probable cause:
Failure of the pitch control mechanism on the engine number four, which caused severe drag and a loss of control.

Circumstances:
The aircraft departed Chita Airport on October 31 on a positioning flight to Minsk with intermediate stops at Krasnoyarsk, Novosibirsk, Omsk, Chelyabinsk and Kuybyshev, carrying a crew of five and four passengers, crew wife's and children. On the leg from Krasnoyarsk to Novosibirsk, weather conditions worsened and the crew elected to gain height due to icing conditions but this was denied by ATC. While cruising at an altitude between 900 and 1,500 meters, the airplane went out of control and entered a dive before crashing in flames in a dense wooded area located near Ribnoye, about 23 km east of Tamozhenka. Due to low clouds and snow falls, rescue teams could be dispatched only a day later but all SAR operations were suspended on November 22 as no trace of the aircraft nor the 9 occupants was found. These operations were restarted in May 1963 and the wreckage was eventually found on May 29, 1963. It was reported the aircraft struck the ground in a 70-80° nose down attitude and disintegrated on impact. Debris were found 200 meters around the point of impact, the engines were found three meters deep into the earth and a part of the right elevator was found 1 km from the main wreckage. The accident was not survivable.
Probable cause:
The accident was the consequence of a loss of control in flight due to an excessive accumulation of ice on the aircraft. The following factors were considered as contributing:
- The operator decided to dispatch a crew who was not familiar with such weather conditions (icing conditions),
- The inexperience of the crew,
- Poor flight organization,
- Lack of coordination between Krasnoyarsk and Novosibirsk control center,
- Lack of assistance from ATC who did not authorized the crew to climb above 2,700 meters where the weather conditions were more suitable.

Circumstances:
While cruising at an altitude of 9,000 meters, the copilot was able to send a short distress call and control was lost. The airplane entered a dive and the descent took about two minutes and thirty seconds before the airplane disintegrated in a wooded area located in Voznesenka, about 28 km east of the Krasnoyarsk Airport. The aircraft was totally destroyed and all 84 occupants were killed. It was later reported that all bodies shows traces of high temperature and burns.
Probable cause:
It was determined that several units of the Soviet Army Forces were involved in a training exercise in the region of Magansk and shot several ground-to-air missiles. One of them struck the left side of the airplane, penetrated the fuselage and caused a hole of 20 cm. Out of control, the airplane entered a dive and crashed.

Circumstances:
The aircraft was performing flight SU005 from Moscow to Khabarovsk with intermediate stops at Krasnoyarsk and Irkutsk, carrying three passengers, a crew of four and a load of various goods for a total weight of 417 kilos. While cruising at an altitude of 3,000 meters, weather conditions deteriorated and the crew encountered thunderstorm activity. Due to severe turbulences, the aircraft went out of control and entered a dive. At an altitude between 500 and 1,000 meters, the airplane disintegrated in the air and all debris scattered in a field and a wooded area located in Komarovo, about 37 km south-southwest of Kansk. All seven occupants were killed.
Probable cause:
It was determined that the loss of control was the consequence of severe turbulences that exceeded the design of certain parts of the airplane. Poor flight preparation on part of the operator and the failure to consider the possibility of a deterioration of the weather conditions were considered as contributing factors. Also, the crew was not properly briefed about weather conditions prior to departure from Krasnoyarsk Airport.

Circumstances:
The crew was supposed to fly from Irkutsk to Novosibirsk but weather conditions at destination deteriorated in flight so the crew was diverted to Krasnoyarsk Airport. While approaching the Krasnoyarsk area by night, the crew was cleared by ATC to descend to 1,500 meters. Descending to the altitude of 1,725 meters in poor visibility, the twin engine aircraft hit the east slope of Mt Sivukha (1,807 meters high) located 30 km from the Mana River. As the airplane failed to arrive in Krasnoyarsk, SAR operations were conducted but eventually suspended few days later as no trace of the aircraft nor the 19 occupants was found. The wreckage was found in June 1955, about 132 km south of the intended route. The aircraft was destroyed upon impact and all 19 occupants have been killed, among them nine foreign citizens (one Polish, one Chinese and 4 Cyprus, four UNO emissaries in Vietnam).
Probable cause:
At the time of the accident, the aircraft was off course by 132 km and deviated from the prescribed flight path from 10° due to strong winds blowing from the northwest up to 130 km/h. Poor flight organisation and follow up, letting the crew descending to 1,500 meters while the minimum safe altitude was 2,100 meters in the area and incomplete information transmitted to the crew regarding wind component that did not reflect the truth were considered as contributing factors.
