Human Error Cited in Japanese V-22 Osprey Accident

An incident involving a V-22 Osprey transport aircraft from the Japanese Ground Self-Defense Force occurred on the remote island of Yonaguni in Okinawa Prefecture last October, and the GSDF has determined that human error was to blame. The accident took place on October 27, during joint exercises with U.S. forces, when the Osprey tipped over during takeoff from a GSDF base, causing damage to its left wing.

According to the GSDF, the mishap ensued because the co-pilot failed to activate the engine speed increase button, while the captain overlooked checking the status. Consequently, the aircraft lost altitude shortly after takeoff due to insufficient power, and the left wing made contact with the ground as the aircraft experienced a violent shaking while attempting an emergency landing.

An investigative committee from the GSDF concluded that the oversight was exacerbated by psychological pressures stemming from a scheduling delay and the unexpected addition of an extra passenger. In response to the accident, the GSDF has grounded its Osprey fleet and intends to resume operations after ensuring that crew members undergo further training.
