Circumstances:
The airplane departed Baku Airport at 1408LT on a cargo flight to Dnipropetrovsk, Ukraine, carrying two engineers from the motorist Zaporozhie, four crew members and a load consisting of five gear boxes for a total weight of 1,366 kilos. After takeoff from Baku, the airplane climbed to an altitude of 2,100 meters and the crew obtained the permission to modify his route to make an intermediate stop at Rostov-on-Don before continuing to Dnipropetrovsk. Doing so, the crew failed to request information about weather conditions en route. Later into the flight, weather conditions worsened and the captain requested the permission to descend to 1,500 meters but this was not possible and ATC instructed the crew to maintain the assigned altitude of 2,100 meters. While cruising in a thunderstorm, the airplane went out of control, partially disintegrated in the air and eventually crashed in a field located 10 km north of Izobilnoye. The aircraft was totally destroyed and all six occupants were killed. It was reported that the left stabiliser was the first part to be sheared off during the descent and was found 850 meters from the main wreckage.
Probable cause:
Loss of control caused by severe downdrafts and turbulences while cruising in a thunderstorm activity. It was reported that the crew has not been informed about the deterioration of the weather conditions.

Circumstances:
The aircraft departed Kostroma Airport at 0730LT with one passenger and seven crew on board. They were in charge to make aerial photography of the railroad from Neya to Svesha via Manturovo and Sharya. After two hours and ten minutes of flight, the left engine failed. The captain decided to divert to Sharya when the right engine overheated shortly later. In such conditions, he decided to attempt an emergency landing when the airplane lost height, struck trees and crashed in a dense wooded area located on km 711, some 600 meters from the railroad. The passenger was unhurt while all seven crew members were injured. Eighteen hours later, the captain died from his injuries. The airplane was destroyed.
Probable cause:
Failure of the left engine in flight due to the dysfunction of the carburetor. The high outside temperature was considered as a contributing factor as the crew was unable to maintain a safe altitude on one engine in such conditions.

Circumstances:
The crew was engaged in a local night training mission at Donetsk Airport. Following five uneventful circuits, the crew started a sixth approach in limited visibility due to poor weather conditions. On final, the pilot-in-command decided to continue the descent after passing the decision height despite the fact he was unable to distinguish the runway lights when the airplane struck trees. It banked right to an angle of 20° and crashed in a field located 380 meters to the right of the approach path and 325 meters from the runway threshold. The aircraft was destroyed and all five crew members were injured. Six days later, the captain died from his injuries.
Probable cause:
It was determined that the crew decided to continue the approach after passing the decision height without any visual contact with the runway light and the ground. In such conditions, the crew should abandon the approach for a go around manoeuvre. It is reported that weather conditions worsened during flight, which was considered as a contributing factor.

Circumstances:
The aircraft was completing a training mission from Malaya Viska to Kirovograd, carrying five crew members and six passengers, one instructor, three auditors and two employees of the company. While approaching Kirovograd Airport by night, the crew encountered poor weather conditions with a limited visibility due to fog, a worse situation than predicted. On final, while at an altitude of 40 meters, the instructor in command was unable to locate the runway and decided to continue the approach. Doing so, he failed to realize that the airplane banked right to an angle of 20° and lost altitude when it struck the ground and came to rest in flames 400 meters to the right of the approach path. Four crew members were killed and seven other occupants were injured. The aircraft was destroyed.
Probable cause:
Wrong decision on part of the instructor who decided to continue the approach in below minima weather conditions. Taking into consideration the fact that the crew was unable to locate the runway at decision height, the instructor should make a go around and divert to another airport or returning to his departure point.

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.

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:
Shortly after takeoff from Gorki-Strigino Airport, while climbing to a height of 140-150 meters, the left engine failed. The crew was unable to feather the propeller and the captain elected to make an emergency landing when he was forced to make a sharp turn to the left to avoid obstacles (building and factory's chimney) when the airplane banked left, causing the left wing tip to struck the ground. The airplane crashed in flames in a field located in Bolchoye Doskino, some 7 km southwest of the airport. A passenger was slightly injured while all 20 other occupants were killed.
Probable cause:
Failure of the left engine during initial climb for undetermined reason, maybe due to a carburetor issue.

Circumstances:
The crew departed Aralsk Airport at 0952LT on an ice reconnaissance mission over the Aral Sea. While cruising at an altitude of 800 meters, the aircraft went into clouds and the pilot decided to reduce his altitude to maintain a visual contact with the sea surface. The airplane descended to an altitude of 400 meters when it flew again in fog. The crew reduced again his altitude, causing the aircraft to struck the ground. The aircraft bounced and crashed 226 meters farther. A crew member and two passengers were killed while seven other occupants were injured. The aircraft was destroyed.
Probable cause:
It was determined that the crew continued under VFR mode in IMC conditions, causing the aircraft to struck the ground. The absence of such reconnaissance mission organization was considered as a contributing factor.
