Circumstances:
Following a normal takeoff roll, the crew started the rotation at a speed of 220 km/h. Five second after liftoff, while climbing to a height of 10 meters, the left engine failed. The left propeller was automatically feathered and the crew continued to climb. 34 seconds after takeoff, the airplane was at an altitude of 30 meters at a speed of 230 km/h when the crew retracted the flaps. Six seconds later, at a height of 40 meters and a speed of 227 km/h, the pilot-in-command initiated a left turn when the airplane drifted to the left. It lost speed then stalled and crashed in flames on a pipeline owned by the Neftyanyye Kamni Oil Company. Two crew members and 54 passengers were killed while eight other occupants were injured.
Probable cause:
It was determined that several blades on the first stage of the turbine have disintegrated due to a reduction of their mechanical properties due to a previous overheating, probably beyond 1,150°. Nevertheless, it was not possible to establish the exact cause of the overheating of the blades and to define the period when this occurred.

Circumstances:
Following an uneventful flight from Warsaw, the crew started the approach to Szczecin-Goleniów Airport by night and relative good weather conditions. On final, the airplane lost height, struck trees and crashed in flames in a wooded area located few dozen meters short of runway threshold. The aircraft was totally destroyed and all 18 occupants were killed, among them the Polish Minister of the Interior Wiesław Ociepka and the Czechoslovak Minister of the Interior Radko Kaska. Accompanied by a delegation of their respective ministry, they were en route to Szczecin to visit sea port installations.

Probable cause:
It was determined that the accident was caused by turbulences created at low altitude by the confrontation of two hot and cold air fronts, a phenomenon which resulted in a sudden loss of altitude that the pilots could not control. An accumulation of frost on all surfaces also contributed to the accident.

Circumstances:
At 2354LT, while cruising at an altitude of 5,700 meters in good weather conditions, the crew was cleared to descend to 4,500 meters and confirmed his ETA in Perm in 15 minutes. Less than two minutes later, the airplane went out of control and entered a dive and reached the speed of 1,000 km/h. At 2,700 meters, the captain was able to regain control for few seconds when the airplane made an upward looping and started to lose parts due to excessive g loads. Out of control, it went down and eventually crashed at a speed of 250 km/h in a field covered by 70 cm of snow and located near Petukhovo, about 90 km north of Perm. The wreckage was found at 1400LT on January 22 and all 39 occupants have been killed. It was later reported that four passengers survived the crash but died due to extreme low temperature (-41° C) before the rescuers arrived on site.
Probable cause:
The exact cause of the accident could not be determined with certainty. It is believed that traces of explosives were found on several debris but this was not proven and the Soviet Authorities confirmed there were no military activities in the area at the time of the accident.

In poor visibility, the aircraft dropped below the glide and hit tree tops some 2,500 meters before the inner marker. The aircraft stalled and crashed in flames in a wooded area. While the aircraft was destroyed, all three crew members were unhurt.
Probable cause:
Wrong approach configuration on part of the crew.

Circumstances:
The airplane was engaged in a weather survey mission over the Baltic sea and was carrying two passengers and a crew of six. While returning to his base at Kaliningrad-Khrabrovo Airport, the crew failed to set the altimeter properly, causing the aircraft to approach the land at an insufficient altitude. In low clouds, the pilot-in-command did not realize his altitude was too low when the airplane struck trees, lost height and crashed in flames 200 meters further onto a school. The airplane was totally destroyed by impact forces and a post crash fire as well as the school building. All eight occupants on board the aircraft were killed as well as 27 people on the ground, 23 children and three adults. Two other children were seriously injured.
Probable cause:
Wrong altimeter setting caused the aircraft to fly at an insufficient altitude. Lack of visibility due to low clouds and poor ATC assistance was considered as contributing factors.

While all 13 occupants were uninjured, the aircraft was damaged beyond repair.
Probable cause:
Unintentional application of thrust reverser on final approach on part of a crew member.

Circumstances:
On approach to Saratov-Tsentralny Airport by night, the crew encountered poor weather conditions with fog, clouds from 100 to 1,000 meters and icing conditions. While approaching at an altitude of 400 meters with flaps and landing gear up, the aircraft nosed down to a 7-9° angle then rolled to the right. It descended with a high vertical speed before crashing in flames 13 km short of runway threshold. The aircraft disintegrated on impact and the wreckage was found 1,300 meters to the right of the approach path. All 57 occupants have been killed.
Probable cause:
The aircraft was approaching at an estimated speed of 240-260 km/h with flaps retracted when it rolled to the right and started an uncontrolled descent with a high vertical speed. It is believed that the loss of control was probably caused by an excessive accumulation of ice on fuselage and wings which adversely modified the aerodynamic characteristics of the aircraft. Investigations determined that the aircraft had flown in icing conditions for a period of 3 minutes and 50 seconds, resulting in an accumulation of 15 millimeters of ice. The reason why the flaps were not deployed could not be determined.
