What happened
While operating at Fukuoka-Itazuke Airport on runway 16, the aircraft began its rotation at a speed of 158 knots. Shortly after entering the initial climb phase, at an altitude of approximately 3 metres, the number one engine experienced a sudden loss of power. This failure was triggered by the separation of a first-stage high-pressure compressor disk fan blade. Following the loss of power, the N1 speed decreased to 23.7%, and the flight engineer notified the crew of the engine malfunction five seconds later.
In response to the engine failure, the captain initiated an aborted takeoff, attempting to return the aircraft to the runway. Upon touchdown, the aircraft experienced a vertical acceleration of 2.1 g. Although the crew deployed the thrust reversers and extended the ground spoilers, the aircraft was unable to stop within the available runway length. The aircraft overran the runway, crossed a nearby road, and skidded for roughly 620 metres into an open field, where it subsequently caught fire. The accident resulted in three fatalities.
Findings
- The primary mechanical failure was the separation of a fan blade from the first-stage high-pressure compressor disk in the right engine.
