Circumstances:
The crew departed Mys Schmidta (Cape Schmidt) with 14,5 tons of fuel to Anadyr. Following an uneventful flight, a load of 10 tons of meat was loaded in Anadyr and the crew left Anadyr Airport at 0625LT bound for Magadan. One hour and twenty minutes into the flight, while cruising at an altitude of 7,000 meters, the radio operator informed ATC that the engine number two failed. The captain started an emergency descent and reach the altitude of 3,000 meters five minutes later when the engine number one failed as well. In such conditions, the crew elected to make an emergency landing on the icy Shelikov Gulf. The airplane belly landed on the ice and slid for several yards before coming to rest 2,700 meters off the coast. It went through the ice and sank. The wreckage and the crew was found six days later, on March 4 at 0830LT. The aircraft was lost and all ten occupants died from hypothermia (OAT -18° C and icy water).
Probable cause:
It was determined that a hot air line located near the engine number two broke in flight. The hot air caused the melting of electrical components and the development of a fire in the engine number two nacelle, followed by the rupture of a fuel hose. Unfortunately, the aircraft was not equipped with life jackets, signaling equipment or warm clothing.

Circumstances:
The crew was performing a check flight at Syktyvkar Airport. During the final approach completed by night, the engines number 1, 2 & 3 flamed out in clouds and icing conditions. The crew was unable to feather the propeller that went in auto-rotation. Due to drag, the aircraft lost speed and height, banked left to an angle of 90°, struck tree tops and crashed in a wooded area located in Verkhnyaya Maksakovka, 10,2 km east of the Syktyvkar Airport. All 7 crew members were killed.
Probable cause:
The engine flame out was probably caused by the air intake iced up. The crew inexperience and the poor efficiency of the air-intake heating system were considered as contributing factors.

Circumstances:
The crew was performing a cargo flight from Pevek to Magadan with intermediate stops at Zyrianka and Seymchan, carrying a load of reindeer skins for a total weight of 800 kilos. Due to strong winds, the airplane deviated from the prescribed flight plan and nor the crew nor ATC were able to note this. While approaching a mountainous area in poor weather conditions, the crew encountered downdrafts. The airplane lost altitude and descended from 2,400 to 1,820 meters in few seconds before crashing on the slope of Mt Tuonnyakh. The wreckage was found four days later some 53 km northwest of Seymchan and all four crew members were killed in the accident.
Probable cause:
The crew failed to follow navigation rules and failed to maintain regular communication contacts with ATC who also failed to assist the crew properly. Information transmitted to the crew and related to wind component did not reflect the truth, which was considered as a contributing factor.

Circumstances:
The takeoff from Tazovskoye Airport was attempted from an icy runway and in marginal weather conditions with a visibility limited to 500 meters and a crosswind gusting to 43 km/h. After a takeoff roll of 1,600 meters, the pilot pulled up and started the rotation when the aircraft banked right and crashed 265 meters farther, about 70 meters on the right of the extended center line. All four crew members and eight passengers were killed while 13 passengers were injured. The aircraft was destroyed.
Probable cause:
The accident was the consequence of a loss of control while taking off in marginal weather conditions. The flight was dispatched despite the fact that the visibility and weather conditions were below minima at the time of the accident. It was also reported that ATC consumed alcohol the night before and failed to have sufficient rest time.

Circumstances:
On final approach to Norilsk-Nezhdanny Airport on a flight from Klin, an inexperienced air traffic controller allowed the crew to descend to 700 meters although the mountains of the Talnakhskiye gory range reach a height of 740 meters in the approach path. The aircraft collided with a mountain top (633 meters) near the Talnashki River and fell into a gorge. Seven crew members were killed and the sole survivor, the tail gunner, was seriously injured. The aircraft was destroyed.
Probable cause:
Poor assistance on part of the ATC who transmit wrong information to the crew while descending to the airport.

Circumstances:
While approaching Kazan on a flight from Kamskoye Ustye, the engine failed. Flying at low height and facing power cables, the captain decided to pass below the cables and to attempt an emergency landing on a highway. After touchdown, the airplane struck a metal slide and obstacles before coming to rest. Both pilots and three passengers were injured while nine other occupants were unhurt. The aircraft was damaged beyond repair. Six hours after the accident, the copilot died from his injuries.
Probable cause:
Engine failure in flight caused by the poor quality of the fuel which was contaminated.

While descending to Olyokminsk, the crew encountered poor weather conditions and followed visually the wrong river Sinyaya instead of Lena. Doing so, the aircraft descended prematurely and its altitude was insufficient while passing the outer marker. The aircraft struck trees and crashed on the slope of a wooded hill (434 m high) located 25 km short of runway threshold. The wreckage was found a day later and all four crew members were killed.
Probable cause:
Unable to determiner his exact position based on the ETA, the crew erroneously followed the Lena River. As a result of a premature descent, the aircraft collided with trees. ATC, unable to assist the flight by radar in marginal weather conditions, unreasonably gave permission to the crew to perform a straight-in approach, based only on the report of the crew.

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:
The aircraft was involved in a post-maintenance test flight and was carrying six technicians and five crew members. Following a normal takeoff roll of 1,550 - 1,600 meters on runway 25, the pilot completed the rotation and a normal initial climb. Following a distance of 800 meters and once the aircraft reached the altitude of 175 meters, it banked left to an angle of 90°, went out of control and crashed in a huge explosion in a wooded area near the airport. The aircraft was totally destroyed and all 11 occupants were killed.
Probable cause:
It was determined that the accident was the consequence of an error on part of the technicians who failed to reconnected the rudder control system according to the manufacturer procedures. It was reported that the system was cross-connected by mistake, causing the aircraft to be uncontrollable.
