Events
On departure from Seoul-Incheon Airport’s Runway 33L, the crew initiated the takeoff procedure. After traveling 6,413 feet along the runway, the aircraft reached V1 speed. At a speed of 182 knots, the crew heard a noise consistent with the failure of both tires No. 9 and No. 10, which are located on the central landing gear. The captain then decided to abandon the takeoff and initiated an emergency braking maneuver.
Due to the aircraft’s total weight of 629,600 pounds, it could not stop within the remaining runway distance of 4,635 feet. The airplane overran the runway end and contacted a grassy area. The nose gear collapsed, and the aircraft subsequently struck various equipment of the localizer antenna. It came to rest 485 meters beyond the runway end.
Damage and Casualties
The aircraft sustained damage that rendered it beyond repair. All four crew members on board escaped without injury.
Probable Cause
The official investigation attributed the accident to the crew’s decision to abandon the takeoff at a speed slightly above V1 following the failure of both tires No. 9 and No. 10 on the central landing gear. The overrun occurred due to a combination of factors: limited time and information available to the crew to evaluate the situation, dynamic instability of the central landing gear resulting from the tire failures, and a 48% reduction in braking performance caused by the rupture of a hydraulic pipe in the primary braking system.
