Accident Sequence
During a night training mission at Kuybyshev Airport, the crew performed several circuits before initiating a new approach. After passing the inner marker, the aircraft descended to an extremely low altitude, approximately one meter above the ground. The airplane then struck a private property fence with its undercarriage, followed by two houses, and ultimately crashed into a garden.
Fatalities and Injuries
Three crew members were killed in the accident, while two others sustained serious injuries. One of the survivors died from his injuries two hours after the crash. No injuries occurred on the ground.
Aircraft Damage
The aircraft was destroyed in the crash sequence.
Probable Cause
According to the official investigation, it was not possible to determine the reason why the crew continued the approach at such a low altitude. However, the assumption that both engines failed due to fuel exhaustion was not ruled out. At the time of the accident, the engines were supplied by the rear right fuel tank, which was almost empty.
