What happened
During the landing phase at Kadena Air Force Base, an aircraft experienced a loss of directional control immediately following touchdown. The plane drifted toward the right side of the runway before eventually coming to a stop off the paved surface. While the incident resulted in the total loss of the airframe, there were no injuries reported among those on board.
Findings
Investigations into the accident identified a mechanical malfunction involving the propulsion system. Specifically, the reverse thrust system on engine number 4 failed to deploy correctly. While the reverse thrust mechanisms functioned as intended on engines 1, 2, and 3, the failure of the fourth engine's system caused it to remain at full power during the deceleration process, leading to the uncontrolled excursion.
