Circumstances:
While descending to Yeysk Airport, the crew proceeded to a fuel transfer from the auxiliary tanks to the main central tank. Shortly later, all four engines stopped almost simultaneously. The aircraft lost height and crashed in the Azov Sea fe km off Yeysk Airport. 25 occupants were killed and 25 others were rescued.
Probable cause:
It was determined that the main central tank had not been drained or cleaned since a long time and a large quantity of water was still present. When the fuel was transferred from the auxiliary tanks to the main central tank, it mixed with water that contaminated the fuel lines, causing all four engines to fail.

Circumstances:
The airplane departed Bataysk on a local training mission with two pilots on board. A second U-2 registered CCCP-L956 took off shortly earlier with also two pilots on board. Sh924 was following L956 when the first aircraft slowed at a speed of 80-85 km/h so the second aircraft could approach. At a height of about 40 metres, the pilot of L956 initiated a turn when both airplanes collided and crashed in a field located 1,5 km from the airport. Two pilots survived and two others were killed.
Probable cause:
Poor organization of the training mission on part of the instructors at Bataysk Airport. Also the crew precipitated the mission and failed to maintain a safe distance while flying in formation.

Circumstances:
The crew departed Bataysk Airfield on a local training mission. After takeoff, the crew encountered engine problems and the airplane climbed to a max height of about 70 metres before it started to descend. The pilot-in-command attempted to find a suitable terrain for an emergency landing when the aircraft nosed down and crashed, bursting into flames. The airplane was totally destroyed and all three crew members were killed.
Probable cause:
The accident was the result of an engine failure, the cause of which could not be precisely determined due to the total destruction of the plane. However, it is believed that it may be caused by a faulty carburation. The loss of control at low height was the result of a pilot error who did not take the necessary measures to ensure that the aircraft's speed was sufficient while he was confused about the choice of a landing zone in an unfavorable environment. Finally, the horizontal stabilizer was stuck at an inappropriate angle, which was considered as a contributing factor.
