What happened
While performing the takeoff roll, the number one engine experienced a sudden explosion. During this event, fragments from the engine were ejected, striking the ground before bouncing upward and impacting the wing structure. This impact resulted in a rupture of the number two fuel tank.
In response to the failure, the crew initiated emergency braking maneuvers to halt the aircraft. The plane came to a complete stop while engulfed in flames. All 65 occupants were able to evacuate the aircraft quickly; however, 23 injuries were reported during the incident. The aircraft was subsequently destroyed by the fire.
Findings
Investigations into the incident concluded that the primary failure originated within the engine's internal components. Specifically, the explosion of the first engine was triggered by the disintegration of the compressor's first stage. The resulting debris path caused the secondary damage to the wing's fuel containment.
