Aircraft flight hours:

Circumstances:
The airplane was engaged in a spraying mission on behalf of the sovkhoz of Vidiskes. In the afternoon, the captain decided to takeoff without the copilot but with two technicians and one engineer. After takeoff, the captain elected to contact ATC in Vilnius but this was not possible as the aircraft's altitude was insufficient (between 150 and 200 meters). Shortly later, the airplane went out of control and struck the ground at high speed. It bounced and crashed 98 meters further in a snow covered field. The captain was seriously injured while all three passengers were killed.
Probable cause:
Lack of discipline on part of the captain who decided to conduct a local flight without any copilot and with three unauthorized people on board. Maneuvers at low altitude in conditions without a second pilot over snowy terrain led to a collision with ground.

Circumstances:
The departure from Bugulma was scheduled at 0805LT but postponed first to 0900LT due to poor weather conditions en route. Shortly before takeoff at 0950LT, three additional passengers enplaned, giving a total of 15 passengers (the maximum allowed was 12). One minute after liftoff, during initial climb, at a height of 15 meters, the airplane's speed decreased to 60 km/h then it veered to the left, stalled and crashed. A passenger was killed while another one was uninjured. 15 others occupants were injured and a second passenger died from his injuries five days later, on November 16. At the time of the accident, weather conditions were considered as normal and the total weight of the aircraft and its CofG were within limits.
Probable cause:
It was determined that the loss of control during initial climb occurred after the pilot got distracted. For any reason, he adopted a wrong takeoff configuration and failed to take appropriate actions to maintain a positive rate of climb and a sufficient speed.

Circumstances:
During initial climb, at a height of about 15-20 meters, the rear cabin door opened accidentally. Two passengers unfastened their seatbelt to close the door. This movement in the cabin caused the center of gravity to move past the rear limit by 37%. The aircraft reached a super critical angle of attack and at a speed of 60-65 km/h, it stalled and crashed in a near flat attitude near the runway (rate of descent estimated between six and eight meters per second). Two passengers were killed while 10 other occupants were injured. The copilot died from his injuries two days later.
Probable cause:
The wrong reaction of two passengers who decided to unfasten their seatbelt to close the cabin door, causing the CofG to be out of aft limit.

Circumstances:
The aircraft took off from Olenek Airport at 1651LT. While climbing to a height of 100-120 meters, the engine lost power. The captain decided to return for an emergency landing and initiated a turn to the left when the airplane stalled and crashed, one minute after takeoff. The aircraft was destroyed and all five occupants were injured.
Probable cause:
It was determined that the loss of engine power was the consequence of the malfunction of the spark plugs due to an excessive accumulation of tetraethyl plumb.
