Circumstances:
The departure from Magadan Airport was completed in light snow conditions. After liftoff, the aircraft encountered difficulties to gain height and rolled left and right. At an altitude of 60-70 meters, the aircraft stalled and crashed six km from the airfield, about two minutes after takeoff. All five crew members and 17 passengers were killed while 10 others were injured, some of them seriously. The aircraft was destroyed.
Probable cause:
It was determined that the total weight of the aircraft was 996 kilos above the MTOW. Also, the crew did not prepare the flight properly and failed to remove the wet snow from the aircraft prior to takeoff, which increased weight, reduced performances and lift. The combination of an overloaded and non decontaminated aircraft caused the accident.

Circumstances:
About a minute after a night takeoff from Irkutsk-Intl Airport, while climbing to a height of 100-120 meters, the captain sent a brief message saying a plane was facing him. He made an immediate sharp turn to the right when he lost control of the airplane that dove into the ground and crashed 2,5 km from the runway end and 500 meters to the right of its extended centerline. Four crew members (the captain, the copilot, the flight mechanic and the radio operator) were killed while all 24 other occupants were injured. The aircraft was destroyed.
Probable cause:
It was determined that no aircraft was present in the vicinity of the climbing Ilyushin II-12 at the time of the accident. The pilot-in-command misinterpreted the light on the top of the inner marker located 4 km from the runway threshold for an incoming aircraft and decided to make in immediate action to avoid any collision.

While flying into the North Korean airspace, the aircraft was shot down by Captain Ralph S. Parr Jr., pilot on a USAF F-86F-30 Sabre. Out of control, the airplane dove into the ground and crashed in the region of Mao-erh-shan, in the Chinese province of Jilin. All 21 occupants were killed, among them high ranking Soviet Navy Officers who were flying from Port Artur (now Dalian) to Vladivostok. It was later reported that the pilot though the aircraft was flying for the North Korean Air Force. Later that day, July 27 1953, the armistice was sign to put an end to the Korean War.
Probable cause:
Shot down by the pilot of a USAF fighter.

Circumstances:
The crew departed Moscow-Vnukovo Airport at 0520LT on a flight to Tbilisi with an intermediate stop scheduled at Rostov-on-Don. Due to the deterioration of the weather conditions and the presence of a storm between Krasnodar and Sukhumi, the crew decided to modify his route and obtained the permission from ATC to divert to Krasnodar. The crew and the passengers waited for few hours at Krasnodar Airport and the aircraft took off at 1507LT bound for Tbilisi. While cruising under VFR at an altitude of 2,400 meters, the crew encountered poor weather conditions with thunderstorm activity, heavy rain falls, turbulence, hail and lightning. Within few minutes, the aircraft was hit by lightning and suffered heavy turbulence so went out of control and entered a dive. At an altitude of 300 meters, the crew elected to regain control but high g forces exceeded the design of the wings that were torn off. Out of control, the airplane crashed in flames in a wooded and hilly terrain located near the village of Grigorishi, about 15 km northeast of Zugdidi. The aircraft was totally destroyed and all 18 occupants were killed.
Probable cause:
Loss of control caused by poor weather conditions consisting of thunderstorm activity with heavy rain falls, hail, turbulence and lightning.

Circumstances:
The aircraft departed Moscow-Vnukovo at 1911LT and continued under VFR at an altitude of 1,200 meters until Kazan. The crew obtained the permission to descent to Kazan and reduced his altitude to 600 and then 300 meters. During 3 to 4 minutes, the aircraft was flying along the Volga River at an altitude of 300 meters when the crew heard a noise and both engines lost power simultaneously. In the mean time, fire erupted from the exhaust pipe and the crew elected to activate the fire extinguisher system on both engines but without success. The captain reduced his altitude in an attempt to make an emergency landing on the Volga River. The airplane crash landed on the water and eventually came to rest near the bank. 22 occupants were able to evacuate the cabin while a passenger died from drowning. The aircraft sank to a depth of 18 meters.
Probable cause:
It was determined that the aircraft collided, at an altitude of 300 meters, with several ducks. A duck hit the left engine while a second hit the top part of the cockpit, just above the windshield. The impact damaged the upper side of the flight deck and a short-circuit occurred on the magneto switch, causing both engines to stop. The crew elected to feather both propellers but this was not possible because the generator did not provide sufficient power at that time.

Circumstances:
The crew was completing the cargo flight SU022 from Novosibirsk to Moscow with an intermediate stop in Kazan, carrying a crew of six and a load of wire coils, electric engines and radio components. Shortly after takeoff from Kazan Airport, while climbing to a height of 150 meters, the aircraft was hit on its empannage by the left engine of an Aeroflot Lisunov LI-2 that was trying to land at Kazan Airport. On a cargo flight from Leningrad to Sverdlovsk with intermediate stops in Moscow-Bykovo Airport and Kazan, the Lisunov LI-2 was registered CCCP-L4582 and was was carrying a crew of five and a load of six brass panels weighing 155 kilos each and a batch of capacitors. Following the collision, both aircraft dove into the ground and crashed in a snow covered field located three km southwest of the airport. Both aircraft were destroyed and all eleven crew members were killed.
Probable cause:
It was determined that the collision was the result of a series of omissions on part of the ATC based at Kazan Airport who failed to coordinate properly the radar coverage and failed to assist the crew adequately. The ATC in charge of the approach instructed the crew of the Lisunov to descend to 300 meters instead of the 900 meters as mentioned in the approach procedures. Due to poor weather conditions that reduced the visibility below minimas, it would be more appropriate that ATC postponed the departure of the Ilyushin II-12 or instructed the crew of the Lisunov LI-2 to follow a holding circuit or to divert to another airport. It was confirmed that both flying crew did not bear any responsibilities in this tragedy.

Circumstances:
The crew was approaching Leningrad-Shosseynaya Airport and obtained the permission by ATC to descend to the altitude of 1,200 meters via corridor number two. While flying into clouds, the airplane collided with an Aeroflot Douglas TS-62 registered CCCP-L1055 that was performing flight SU381 to Minsk with seven people on board. It just took off from the same airport and its crew received the permission to climb to the altitude of 2,700 meters via the same corridor number two. At the altitude of 1,200 meters, both aircraft collided, dove into the ground and crashed in a field located near the village of Skvoritsy, about 23 km southwest of Leningrad-Shosseynaya Airport. Both wreckage were found 1,200 meters from each other and all 31 occupants were killed.
Probable cause:
It was determined that the collision was caused by an error on part of the ATC services. Despite the fact that both aircraft were tracked on radar screens, ATC based at Leningrad-Shosseïnaya Airport failed to take appropriate actions to ensure a minimum safe separation between both airplanes and failed to realize that they were flying in the same corridor in an opposite direction and at the same altitude. Investigations revealed that the collision was the result of successive errors on part of the ATC who failed to ensure an efficient radar surveillance and transmitted to both crews inappropriate instructions that led both aircraft on the same track.

Circumstances:
The crew left Novosibirsk-Severny Airport at 1400LT for a local training flight. At that time, weather conditions were poor with overcast at 200 meters, rain showers, visibility less than three km and icing conditions in clouds. While flying into the clouds at an altitude estimated between 1,200 and 1,250 meters with the left engine inoperative, the pilot-in-command lost control of the airplane that turned to the left, dove into the ground and crashed in flames few km from the airport. A crew member was injured while eight other occupants were killed.
Probable cause:
The exact cause of the accident could not be determined with certainty. However, it was reported that the left engine was inoperative at impact and that the propeller was feathered, a configuration apparently intended by the crew and part of the training program.
