Fukuoka-Itazuke Airport Takeoff Rejection and Overrun (PK-GIE)

Incident Overview and Engine Failure During Takeoff Roll and Initial Climb During the takeoff roll on runway 16 at Fukuoka-Itazuke Airport, the captain initiated rotation at a speed of 158 knots. During the initial climb, at an altitude of approximately 3 meters, the right engine experienced a loss of power. The failure was caused by the separation of a fan blade located on the first stage of the high-pressure compressor disk. Following the incident, the N1 parameter dropped to 23.7%. Five seconds later, the flight engineer notified the crew of the failure of engine number 1. The captain subsequently decided to abort the takeoff and landed back on the runway. The aircraft made ground contact with a vertical acceleration of 2.1 g, after which thrust reversers were deployed and ground spoilers were extended. Because the aircraft was unable to stop within the remaining distance, it overran the runway, crossed a road, and skidded for approximately 620 meters before coming to rest in an open field, where it burst into flames. Three passengers were killed in the incident. ## Official Findings and Contributing Factors The official investigation determined that the takeoff was aborted even though the CAS was well in excess of V1 and the aircraft had already lifted off from the runway. Consequently, the aircraft departed the end of the runway, came to rest, and caught fire. It is estimated that a contributing factor to the rejection of the takeoff under these circumstances was the fact that the CAP's judgment in the event of the engine failure was inadequate. The investigation revealed that the turbine blade that failed had operated for 30,913 hours and 6,182 cycles. General Electric had advised customers to discard blades after approximately 6,000 cycles.
