What happened
During the takeoff phase at Samarkand Airport, the pilot attempted to rotate the aircraft once it reached a speed of 350 km/h. During this maneuver, the crew discovered that the elevators were in a blocked position. In an attempt to rectify the situation, the captain tried to unlock the elevator controls while the aircraft was still on the runway.
As a result of the mechanical issue and the subsequent maneuvers, the aircraft overran the runway. The impact caused the undercarriage to separate from the airframe. Following the overrun, a fire broke out, which ultimately led to the total destruction of the aircraft. There were zero fatalities and zero injuries reported among the occupants, as everyone managed to evacuate the wreckage safely.
Findings
Investigations into the incident concluded that the primary reason for the event was inadequate flight preparation. The crew failed to adhere to the standard pre-departure checklist, which resulted in the failure to unlock the elevators before beginning the takeoff roll.
