What happened
During a takeoff roll from runway 33L at Seoul-Incheon Airport, the flight crew reached a speed of 182 knots after traveling 6,413 feet. At this point, an audible noise indicated that both the ninth and tenth tires on the central landing gear had failed. In response to the malfunction, the captain aborted the takeoff and applied emergency braking.
Despite the braking efforts, the 629,600 lbs aircraft could not stop within the remaining 4,635 feet of the runway. The aircraft subsequently overran the runway end and entered a grassy area. During the excursion, the nose landing gear collapsed, and the aircraft collided with several pieces of localizer antenna equipment. The plane eventually came to a stop 485 meters beyond the runway threshold. There were no injuries among the four crew members, though the aircraft was determined to be a total loss.
Findings
- The primary factor leading to the excursion was the simultaneous failure of two tires on the central landing gear assembly.
