Circumstances:
18 seconds after it started the takeoff roll, after a distance of 360 meters, while at a speed of 150 km/h, the copilot pointed out a problem with the nose gear and asked if the rudder and elevators were unlocked. At this time, the captain realized that a takeoff was not possible and instructed to abandon the takeoff procedure. Engine power was reduced and an emergency braking procedure was initiated. At this time, the aircraft's was 300 meters from the runway end at a speed of 215 km/h. 18 additional seconds elapsed from the copilot's remark. Unable to stop within the remaining distance, the airplane overran, rolled for 540 meters then collided with an embankment and came to rest in flames against trees. 12 occupants were injured while seven passengers were killed. The aircraft was partially destroyed by a post crash fire.
Probable cause:
It is believed that control column was blocked and a take-off was impossible in such conditions. Various technical investigations could not precisely determine the causes of this anomaly which could be consecutive either to a human error or to the malfunction of the system as a result of the presence of corrosion on connectors, which would affect the alarm of the locking system. The decision to abort the takeoff procedure was taken too late, which was considered as a contributing factor.

Circumstances:
During the takeoff roll, at a speed of 230 km/h, the engine n°4 failed. The captain decided to abandon the takeoff procedure and started an emergency braking maneuver. Unable to stop within the remaining distance, the airplane overran at a speed of 100 km/h, went through a road and a ditch before coming to rest, broken in two. 20 passengers were injured, three of them seriously as they were not wearing their seat belt. Few hours later, one of them died.
Probable cause:
It was determined that the engine n°4 failed after colliding with birds during the takeoff roll, causing the high pressure turbine to fail. Several errors on part of the flying crew contributed to the accident, such as a wrong decision on part of the captain, his lack of knowledge about the time needed between the engine full power mode and the activation of the reverse mode. Also, the thrust reverse systems were activated on both left engines only as the flight engineer failed to activate the thrust reverse system on engine n°3.

During a crop-spraying flight for the kolkhoz (collective farm) im. Kalinina in the Buka district of the Tashkent region (Uzbekistan), while flying at a height of 10 meters, the single engine airplane collided with a high-voltage power line located between the villages of Dzharkishlak and Kashka (near Almalyk). Out of control, it crashed in a cotton field 94 metres further on and nosed over. The captain was killed instantly while the copilot died while being transferred to the hospital. It was determined that the accident occured while the crew was spraying a field which has not to be sprayed.
Probable cause:
Lack of discipline on part of the crew who failed to realize he was flying at an insufficient altitude and failed to locate the high-voltage power line.
