Incident Overview
Following its touchdown at Kadena Air Force Base, the aircraft experienced a loss of control during the landing roll. The airplane deviated from the runway centerline, veering off to the right side before eventually coming to a complete stop. Despite the severity of the excursion, there were no reported injuries among those on board.
Damage and Outcome
The structural damage sustained by the airframe during the incident was significant enough that the aircraft was written off as a total loss. The event highlighted critical safety concerns regarding post-landing systems performance.
Probable Cause Analysis
Official investigation findings identified a specific mechanical failure as the root cause of the accident. The reverse thrust system on engine number four failed to deploy correctly after landing. Consequently, this engine continued to operate at full power while the aircraft was attempting to decelerate. In contrast, the reverse thrust systems on engines numbers one, two, and three functioned properly, creating an asymmetric thrust condition that led to the loss of directional control.
