Circumstances:
Rotation from Vilnius Airport was completed at a speed of 115 km/h. After liftoff, the airplane encountered difficulties to gain height due to a high angle of attack. In stall conditions, the aircraft lost height, causing the left wing to struck the ground. Out of control, the airplane struck a ditch and two poles before coming to rest in flames 1,400 meters past the departure point. A crew member was killed while four other crews were seriously injured. All four passengers were unhurt and the aircraft was destroyed by fire.
Probable cause:
Wrong takeoff configuration on part of the captain who departed with an insufficient speed and a too high angle of attack after liftoff. At the time of the accident, the total weight of the aircraft was 79 kilos above the MTOW, which was not considered as a contributing factor.

Circumstances:
On final approach to Karaganda by night, the crew encountered marginal weather conditions and low visibility. As he was unable to locate the runway, the captain decided to abandon the approach and made a go around. Few minutes later, while on a second attempt to land, the approach speed was too low. The airplane stalled, causing the right wing to struck the ground. Out of control, the airplane crashed 600 meters short of runway threshold and 71 meters to the left of its centerline. Eight people were injured and a passenger was killed while all 20 other occupants were unhurt. The aircraft was destroyed.
Probable cause:
The crew decided to continue the approach in below minima weather conditions (night, fog and low clouds down to 50 meters above the ground) instead of diverting to a suitable airport. It was determined that the pilot-in-command was focused on the runway location so he failed to pay attention to the instruments. Doing so, he did not realized his approach speed was insufficient during the last segment, causing the airplane to stall.

Circumstances:
The aircraft was performing a cargo flight from Milkovo to Khalaktyrka, carrying a crew of four and a load of 46 bags of potatoes for a total weight of 2,536 kilos. The crew started the descent in clouds and did not realize he was not following the assigned route for Khalaktyrka. At an altitude of 2,100 meters, the airplane struck the north face of Mt Aag (2,319 meters high) located 42 km north of Khalaktyrka. The wreckage was found a day later and all four crew members were killed.
Probable cause:
It was determined that strong winds were blowing at 60 km/h at the time of the accident, causing the airplane to deviate 12° from the prescribed route. Due to clouds, the crew was unable to distinguish the mountain. Lack of ATC assistance was considered as a contributing factor.

Circumstances:
On a flight from Nizhniye Kresty (now Cherski) to Pevek on a survey flight of the icy continent, the copilot decided to cut the route short when the captain was in the passenger cabin and overflew Cape Shelagski (469 meters). On approach to the cape, the aircraft was caught by strong downdraft and eventually struck the hill with the lower fuselage, was thrown up into the air again and eventually crashed into a large boulder and caught fire. Three crew members were rescued while seven others occupants were killed.
Probable cause:
Wrong decision on part of the copilot who decided to modify the route without referring to the captain and against all published procedures.

Circumstances:
The aircraft departed Uchur in the morning on a supply mission to a geological camp located in the region of the Kovrik River. The crew successfully performed a first drop and continued along the Kovrik Valley in an attempt to make a second low pass. While cruising at low height, the captain realized he was too low and elected to return, made a sharp turn to the left when control was lost. From a height of about 20-25 meters, the aircraft bank left, stalled and crashed 1,900 meters from the drop zone. The aircraft was destroyed upon impact and all nine occupants were killed.
Probable cause:
The accident was the consequence of poor pilot techniques and wrong decisions on part of the captain who failed to recognize that he was flying too low and at an insufficient speed while performing a sharp turn to the left in a mountainous area. The following factors were considered as contributory:
- Too low altitude to expect recovery when stall occurred,
- The crew continued the flight at an insufficient height in a mountainous area,
- Poor flight preparation,
- Wrong approach configuration.

Circumstances:
During the takeoff roll on a 750 meters long icy runway, while at a speed of 70-80 km/h, the left ski struck an irregularity on the ground. The airplane bounced, climbed to a height of 1,5-2 meters then stalled and crashed 300 meters farther. All six crew members were uninjured while the aircraft was damaged beyond repair.
Probable cause:
Wrong takeoff configuration on part of the crew who attempted to takeoff at an insufficient speed. The captain should abandon the takeoff procedure instead to continue in such conditions. The following factors were considered as contributing:
- The braking performance was reduced due to the high salting of the ground,
- The 'runway' surface was uneven.

Circumstances:
The crew departed Novosibirsk-Severny Airport on a geophysical mission. En route, the right engine failed. Instead of feathering the propeller, the crew attempted few times to restart it but without success. Due to high drag, the airplane lost height and the speed decreased. The captain elected to make an emergency landing on a terrain located between the villages of Morozovo and Tavolgan. At a height of 330 meters, the different probes used for the mission were reinstalled in the cabin when the aircraft stalled and crashed in a wooded area. Five crew members were killed while three others were injured. The aircraft was destroyed.
Probable cause:
It was determined that the right engine failed because the fuel selector was connected to an empty fuel tank. Poor crew coordination and failure to follow the published procedures.

All six occupants were rescued while the aircraft was damaged beyond repair.
Probable cause:
Negligence on part of the captain who decided to start the descent prematurely without knowing his exact position, in clouds without visual contact with the ground.

After decending successively to 600 meters and 300 meters in marginal weather conditions (limited visibility to 4 km in rain and snow, low clouds), the pilot decided to continue the descent despite he could not clearly locate the runway. On short final, the airplane struck the snowy ground and plunged in a deep snow layer (60 cm), slid for several yards and came to rest 250 meters short of runway threshold. All occupants were evacuated safely while the aircraft was damaged beyond repair.
Probable cause:
Wrong approach configuration on part of the captain who decided to continue the descent without clear visual contact with the runway.

Circumstances:
The crew departed Stalino on a cargo flight to Izhevsk with intermediate stops at Kharkov, Voronezh, Penza and Kazan, carrying a load of bottles of zinc nitrate for a total of 2,250 kilos. On the last leg from Kazan to Izhevsk, while in cruising altitude, the crew informed ATC that a fire erupted in the cabin and requested the permission to divert to the nearest airport. An emergency was declared and the captain decided to reduce his altitude and to attempt an emergency landing in a field when the airplane struck the ground, exploded and crashed. The aircraft was totally destroyed upon impact and all four crew members were killed.
Probable cause:
It was determined that some bottles of zinc nitrate broke in flight, causing the fluid to leak in the heating system and to ignite when the heating system was turn ON by the crew (the ignition point of zinc nitrate is 36° C). A fire erupted in the cabin, forcing the crew to attempt an emergency landing. Upon touchdown, several bottles broke and exploded, causing a major explosion of the aircraft that was uncontrollable and crashed in flames. Investigations were able to determine that the Chemical Company in charge to ship the load from Stalino to Izhevsk failed to secure the bottles properly. Also, the operator (Aeroflot) has not been notified of the content of the shipping and thus, the crew was not aware of the nature of the load. Doing so, the Chemical Company violated all dangerous goods procedures.
