What happened
A training mission commenced from Iwakuni Air Base at 0900LT, flying over the Sea of Japan. During the mission, the aircraft returned to the base at 1045LT to perform a series of touch-and-go operations on runway 02.
While executing one of these landing procedures, the aircraft lost control immediately after making contact with the runway surface. The impact caused the aircraft to crash adjacent to the runway, which subsequently resulted in a post-crash fire. The accident resulted in four fatalities among the crew members.
Findings
The aircraft became uncontrollable upon touchdown during a routine training maneuver.
