Circumstances:
The aircraft departed Syktyvkar Airport at 2228LT on a flight to Moscow via Gorki and the crew received the permission to climb to 3,000 meters. 18 minutes later, the crew reported icing conditions and received the permission to climb to 3,600 meters. Three minutes later, at 2249LT, the crew reported that the right engine caught fire and requested the permission to divert to the nearest airport. Apparently, the crew was unable to extinguish the fire and the captain completed a rapid descent. After passing the last cloud layer, at an altitude of 100-150 meters, the airplane went out of control and crashed in flames in a field located 500 meters from the village of Chernovo, some 134 km northeast of Gorki Airport. The aircraft was totally destroyed upon impact and all 14 occupants have been killed.
Probable cause:
Failure of the cylinders and pistons on the right engine in flight which caused a fuel and hydraulic leak. Both fluids caught fire when contacted high temperature equipment of the engine. The right engine totalized 1,164 hours and 390 hours since last overhaul.

Circumstances:
The crew departed Leningrad-Shosseynaya Airport at 0947LT for a local training mission. At this time, weather conditions were poor with low clouds down to 200 meters, mist and a visibility less than 5 km. Thus, the crew was instructed to complete the training mission in the vicinity of the airfield. At the beginning of the afternoon, ATC authorized the crew to continue the mission and while cruising at an altitude of 2,100 meters, the pilot-in-command lost control of the airplane that went into a dive. After crossing the last cloud layer, the pilot elected to regain control but it was too late. The airplane crashed and exploded in a field located in Dachnoe, less than a km north of the airfield. The aircraft was totally destroyed and all nine occupants were killed, among them three pilots, four instructors and two passengers.
Probable cause:
The loss of control occurred while the crew was simulating the failure of the right engine in cloudy conditions. Most probably due to successive errors, or maybe due to a spatial disorientation that affected the pilot-in-command, the airplane went out of control and entered a dive. The pilot elected to regain control after passing the last cloud layer (200 meters from the ground) but the distance between the aircraft and the ground was insufficient. The presence of two civilians on board was against the published regulation.

Circumstances:
The airplane departed Minsk Airport at 1245LT bound for Brest. While cruising at an altitude of 9,000 feet, the crew noted that the oil temperature on the right engine increased while the temperature of the second breech dropped. In such situation, the captain decided to shot down the right engine, feathered its propeller and continued to Brest. At 1405LT, he notified his situation to ATC and started the descent to Brest Airport in marginal weather conditions. On final approach, at an altitude of 40 meters, the undercarriage and flaps were lowered when the captain was instructed to go around. For unknown reason, he continued the approach and the right main gear touched down 390 meters past the runway threshold. The left main gear touched down 73 meters farther and after a course of 930 meters, the airplane overran and collided with the ILS antenna before coming to rest in flames. All 21 passengers were injured while five crew members were seriously wounded. The board mechanic died from his injuries five hours later. The aircraft was destroyed.
Probable cause:
The right engine has to be shut down in flight because of the failure of the second cylinder due to a manufacture defect. Following poor techniques on part of the captain, the approach configuration on one engine was wrong and the third turn on final was completed too late. Marginal weather conditions, a wet runway surface and a limited visibility were considered as contributing factors.

Circumstances:
The aircraft was performing a special flight from Mys Schmidta to Moscow with polar researchers from the Soviet Air Force on board. On the leg from Arkhangelsk to Cherepovets, the crew encountered poor weather conditions and was flying at an insufficient altitude when the airplane struck the slope of Mt Belaya located in the region of Fedorovskaya, about 315 km southwest of Arkhangelsk. The aircraft was destroyed and all 18 occupants have been killed. At the time of the accident, weather conditions were as follow: visibility 4 km below cloud layer at 300 meters, fog, wind at 10 km/h and rain.
Probable cause:
It was determined that the captain decided to continue the flight at an insufficient altitude in poor weather conditions (below minima). Informations related to weather conditions were incomplete, which was considered as a contributing factor.

Circumstances:
The flight was performed at 3,000 meters under VFR mode above clouds. But while approaching Syktyvkar, weather conditions worsened with thunderstorm activity. The crew elected to modify his route to avoid this poor weather area when control was lost. The airplane entered a dive, lost its both wings and eventually crashed in flames in a dense wooded area located 87 km southwest of the Syktyvkar Airport. The wreckage was found 11 days later, on July 31. The airplane was completely destroyed and all 23 occupants were killed. The right wing and the right engine were found 80 meters from the main fuselage.
Probable cause:
It was determined that the loss of control was caused by the combination of strong atmospheric turbulences and vertical downdraft encountered while the aircraft was flying in a low pressure area. During the dive, excessive G loads caused the wings to detach and the aircraft became totally uncontrollable. The lack of assistance on part of the meteorology services was considered as a contributing factor as no one transmitted any information to the crew about the deterioration of the weather conditions and the presence of a thunderstorm on the flight path.

Circumstances:
After his departure from Sukhumi Airport, the crew continued to the southeast bound for Kutaisi at an altitude of 1,200 meters when poor weather conditions were encountered with clouds from 600 to 1,000 meters. Following a navigation error, the aircraft deviated 17 km to the north when it struck trees and crashed in flames on the north slope of Mt Rech (1,436 meters high) located near Tkvarcheli. The wreckage was found a day later. The airplane was completely destroyed by impact forces and a post crash fire and all 31 occupants were killed.
Probable cause:
It was determined that the accident was the consequence of a navigation error on part of the crew, causing the aircraft to be off track by 17 km to the north. The following factors were considered as contributing:
- The crew was hastily fixed the day prior to the accident on a complexe routing,
- In spite of this complexity, the operations of the company failed to join a navigator to the crew, either a mechanic,
- Poor flight preparation,
- Poor weather assessment,
- The crew failed to make fix point after his departure from Sukhumi,
- Absence of radio monitoring on part of the Sukhumi services,
- Meteorologists failed to inform the pilots about the wind component and the weather conditions along the route,
- Shortcomings were noted with ATC services as the person in charge to follow the plane was a trainee who was not authorized to work independently. It was noted that for 20 minutes (a period corresponding to a distance of 100 km), the crew did not receive any ATC messages about his position or flight path.

Circumstances:
At 0927LT, while cruising at an altitude of 3,600 meters, the radio operator informed ATC he was cruising under VFR and spotted Derbent. A minute later, while in clouds, the airplane struck the southeast slope of Mt Kushtang located about 27 km northeast of Boysun. SAR operations were conducted but eventually suspended few days later as no trace of the aircraft nor the 30 occupants was found. All operations were abandoned one month later. The accident was officially announced by the Soviet Authorities on 19JAN1960. On 02JUN1960, alpinists found the wreckage of the airplane in a rocky and craggy area at an altitude of 3,501 meters. Among the passengers were two Chinese and three Germans, the rest of the passengers being Soviet soldiers and members of their families.
Probable cause:
The accident was the consequence of several navigation errors on part of the flying crew who decided to cut the route, apparently to save time. The captain decided to continue under VFR in IMC conditions and at the time of the accident, the aircraft was about 40 to 50 km off course to the right of the intended route. It was not possible to distinguish the mountain that was shrouded in clouds. Also, the crew failed to take into consideration the wind component, which remains a contributing factor.

Circumstances:
On approach to Moscow-Vnukovo, the crew encountered marginal weather conditions with clouds and limited visibility. By night, the aircraft passed below the glide until it struck tree tops and crashed in flames in a wooded area located 1,400 meters short of runway 02 threshold. The aircraft was destroyed by impact forces and a post crash fire and only one passenger survived. Among those killed were the Russian composer Sergei Artyomevich Agababov aged 32.
Probable cause:
The accident was the consequence of poor approach techniques on part of the flying crew who allowed the aircraft to descent below the glide in poor visibility until the airplane struck obstacles. Following factors were considered as contributory:
- The crew was tired and failed to observe a sufficient rest time,
- At the time of the accident, the crew was on duty since 13h50 with 5h53 cumulated flying hours,
- The pilots performances were diminished by fatigue and work overload,
- The copilot's experience was insufficient,
- Poor visibility due to the night and a cloud layer down to 60 meters from the ground.
