What happened
While performing a takeoff roll on runway 30 at Ashiya Airbase, the aircraft encountered a critical mechanical issue. At a speed of approximately 70 knots, the right engine experienced a sudden loss of power. In response to the failure, the captain initiated an emergency braking procedure in an attempt to abort the departure.
Despite these efforts, the aircraft was unable to come to a complete stop within the 6,000-foot length of the runway. The momentum caused the plane to overrun the paved surface and enter an adjacent grassy area. During the excursion, the aircraft's undercarriage was lost. While the airframe sustained damage beyond repair, all seven crew members were evacuated from the scene without injury.
Findings
Investigations into the incident focused on the sudden malfunction of the propulsion system. The primary factor identified was the loss of power in the right engine, though the specific underlying reason for this failure remains undetermined.
