On March 23, 1994, Aeroflot Flight 593, which was an A310-304, crashed into a hill in the Kuznetsk Alatau mountain range in Kemerovo Oblast, Russia, killing all 63 passengers as well as 12 members crew on board.
Relief pilot Yaroslav Vladimirovich Kudrinsky’s children – his 16-year-old son Eldar and 12-year-old daughter Yana – were also among the passengers. Having been cleared at the time, the children visited their father in the cockpit at the start of the flight.
During the flight, the relief pilot’s children visited the cockpit, where Yana took the pilot’s left front seat. By adjusting the heading on the autopilot, Kudrinsky gave her daughter the impression that she was turning the plane, when in reality she had no control over it. The pilot’s seat was soon occupied by Eldar Kudrinsky, the pilot’s son and he was able to contradict the autopilot for 30 seconds unlike his sister after applying enough force to the stick.

Inputs from Eldar Kudrinsky’s control column caused the flight computer to switch the aircraft’s ailerons to manual control while maintaining control over the other flight systems and as a result the aircraft swayed. is tilted to the right. When the flight path representation on the screen changed to show a 180 degree turn, the pilots failed to notice the warning lights and became confused. By the time it took the pilot to notice the problem, the bank angle had steepened to nearly 90 degrees.
After that, the aircraft began to stall and automatically entered a nose-down attitude to recover. Once the pilots regained control, they attempted to exit the dive. They succeeded, but overcompensated and the aircraft stalled again. The aircraft entered a spin due to its steep angle of attack this time. Although the pilots were able to recover, the plane had lost a lot of altitude by the time they did. The plane crashed into the Kuznetsk Alatau mountain range in Kemerovo Oblast, killing everyone on board.
The actions and distraction of the children in the cockpit contributed to the accident. Allowing them to take control was against the rules. No technical failure was detected. Unfortunately, there is also evidence that if the pilots had left the controls to the autopilot instead of adjusting manually, the situation would have been restored.
