The aircraft was engaged in a cargo flight from Leningrad to Kiev with an intermediate stop in Minsk-1, carrying a load of 1,151 kg of glue. Following a normal takeoff roll, the pilot-in-command started the rotation at a speed of 130 km/h. Immediately after liftoff, the aircraft had a tendency to veer left so the pilot compensate to the right when the tail wheel struck the ground 35 meters to the left of the runway and was torn off. The airplane continued for dozen meters then crashed into the snow some 245 meters to the left of the runway. All six occupants were seriously injured and the aircraft was destroyed. Few hours later, the radio operator died from his injuries.

Probable cause:

It was determined that the loss of control was the consequence of an overloaded aircraft by 687 kilos. The following factors were considered as contributing:
- The rotation was completed at an insufficient speed considering the total weight of the aircraft,
- The airplane was trimmed 3° down prior to takeoff,
- The CofG was far aft,
- The copilot and the flight engineer were overduty,
- Reception, delivery and loading of cargo were made by the copilot and the flight engineer which adversely affected their working capabilities during takeoff.

Circumstances:

On a positioning flight from Chelyabinsk to Magnitogorsk, the crew encountered below-minima weather conditions (heavy snow falls and limited visibility). While cruising at an altitude of 300 meters, the pilot lost control of the aircraft that crashed in a snow-covered field located near Tokmasskiy, some 18 km northeast of Uyskoye. The wreckage was found 6 km off course and both pilots were killed.

Probable cause:

Loss of control after the pilot-in-command suffered a spatial disorientation.

Circumstances:

Following an uneventful flight by night at an assigned altitude of 8,400 meters, the crew was cleared to descent to 2,400 bound for Kilpyavr AFB near Murmansk. While in a 3° nose-down attitude, the airplane struck the snow covered slope of a hill (240 meters high), slid for 624 meters then lost its both engines and wings and came to a halt, broken in two. The wreckage was found 29,5 km from the airport and 8 km to the right of the extended centerline. Eight passengers and three crew members (the captain, the navigator and the flight engineer) were killed while 27 other occupants were injured.

Probable cause:

It was determined that the pilot-in-command started the descent prematurely, causing the aircraft to descend below the minimum prescribed altitude. The lack of visibility caused by night and the absence of any visual reference points on the ground did not allow the crew to know his exact position and to distinguish the ground obstacles. ATC allowed the crew to perform a straight-in approach with radar control. The following factors were considered as contributing:
- Absence of an established approach procedure,
- Intermittent loss of VHF communications during the approach procedure,
- The relative inexperience of the flying crew with less than 500 flying hours on this type of aircraft.

Circumstances:

Following an uneventful flight, the crew was cleared to descent to 2,700 meters and received all information related to the destination airport. Shortly later, the crew informed ATC about their ETA in eight minutes. As the pilot has the runway in sight, he was cleared to descend to 600 meters. While cruising at an altitude of 1,020 meters at a speed of 350 km/h in a 7° nose-down attitude and a 3° left bank, the airplane struck the slope of a mountain (1,081 meters high) located 40 km from the airport. The airplane disintegrated on impact and all 34 occupants were killed.

Probable cause:

It was determined that the ground collision was the consequence of a premature descent on part of the pilot-in-command who continued the approach below the minimum safe altitude. The lack of visibility caused by night and the lack of assistance on part of ATC were considered as contributing factors.

Circumstances:

The aircraft departed Makhachkala Airport at 1829LT and climbed over the sea. Less than two minutes later, the crew was cleared to climb to 2,100 meters when the pilot reported to ATC the presence of clouds over the sea that were not mentioned in the weather bulletin transmitted to him prior to the flight. Suddenly, the aircraft nosed down and plunged into the sea about 3,5 km offshore. The wreckage was found in a depth of 10 meters and all 17 occupants have been killed.

Probable cause:

It was determined that, at an altitude of 400 meters while climbing, the airplane struck a flock of migratory birds that struck the windshield that broke instantly, killing both pilots. It was reported that many birds were migrating in this region, at any time during this period of the year.

A first AN-2 registered CCCP-35082 departed Penza Airport at 1012LT on a positioning flight to Kazan. The AN-2 registered CCCP-35083 departed three minutes later on the same routing with one passenger and two pilots on board. For unknown reason, the crew of CCCP-35083 wanted to reach the first crew so they accelerated and joined the first aircraft about 20 minutes later. Due to poor judgement, the engine of CCCP-35083 struck the base of the tail of CCCP-35082. Out of control, it nosed down and crashed inverted in an open field located near Lunino. The airplane was destroyed and all three occupants were killed. The other aircraft was able to land without further problem.

Probable cause:

Poor judgement and wrong actions on part of the flying crew.

Circumstances:

The aircraft was completing a cargo flight from Moscow to Anadyr with intermediate stops in Syktyvkar and Katanga, carrying a load ot 9,905 kilos of oranges and 384 kilos of mail. Both legs between Moscow-Sheremetyevo, Syktyvkar and Katanga were uneventful. The crew started the approach to Katanga by night and marginal weather conditions (low clouds, snow falls and a visibility of 5 km) when he was cleared to descent to 400 meters. At high speed, flaps and undercarriage raised, the airplane banked left to 20-25° when it struck trees and crashed in flames in a wooded area located 13 km short of runway threshold. No distress call was sent from the crew prior to the accident. The aircraft was totally destroyed upon impact and all eight occupants have been killed.

Probable cause:

It is believed that the loss of control was the consequence of an excessive accumulation of ice on wings and stabs during an approach by night in severe icing conditions.

Circumstances:

The aircraft was completing a cargo flight from Moscow to Yakutsk with intermediate stops in Amderma, Khatanga and Magadan, carrying a load of fruits (grapes, pears and lemons) for a total weight of 10,776 kilos. Following an uneventful flight from Sheremetyevo Airport, the crew started the approach to Amderma and was cleared to descent to 600 meters. At high speed, flaps and undercarriage retracted, the airplane was on a straight-in approach when it banked left in a 40° angle and crashed in a prairie located 15 km short of runway. The aircraft disintegrated on impact and debris were found scattered on 540 meters long and 180 meters wide. All 12 occupants were killed.

Probable cause:

The exact cause of the accident could not be determined with certainty. However, it is believed that the accident may have been caused by an excessive accumulation of ice on wings and stabs. Also, it could be possible that the loss of control was the consequence of a technical problem with the autopilot system.

Circumstances:

The crew started the approach to Nizhnevartovsk Airport by night and marginal weather conditions. Due to erroneous calculations, the aircraft was not properly aligned on the approach path and the captain decided to make a go-around. Six minutes later, he initiated a second approach. On short final, ATC asked the pilot if he has the runway in sight. As the answer was positive, the crew was cleared to land. Less than a minute later, the airplane struck tree tops, stalled and crashed in flames in a wooded area located 1,092 meters short of runway threshold. 32 occupants were injured while 24 others were killed, among them the copilot and a flight attendant.

Probable cause:

It was determined that the propellers went inadvertently into reverse when the crew activated the engine de-icing system. It was later discovered during investigations that there was a conception error on this type of aircraft between the de-icing systems and the thrust reversal systems that could activate simultaneously. Nevertheless, when control was lost, the flaps were deployed in an angle of 17° instead of 38° as prescribed, which was considered as a contributing factor.
