Gov't claim of Osprey safety crumbles after 5 years
The rate of severe accidents involving the U.S. Marines' MV‐22 Osprey aircraft has gone up by about 1.5 times from the figure released by the Japanese government before they were deployed at U.S. Marine Corps Air Station Futenma in Okinawa Prefecture five years ago.
The U.S. Marines categorizes accidents that cause damages of at least $2 million, or involve deaths as Class A mishaps.
According to the Marines, Ospreys logged 303,207 flight hours from October 2003 and the end of August 2017. Nine of the accidents that took place in that time were Class A, bringing the accident rate to 2.97 per 100,000 flight hours. This is much higher than the 1.93 accident rate as of April 2012, a figure released by the Japanese Ministry of Defense in October 2012.
The Japanese government had emphasized the safety of the Osprey prior to its deployment at Futenma by underscoring the fact that its 1.93 accident rate was lower than the 2.45 accident rate among U.S. Marine aircraft overall at the time.
A Ministry of Defense official said, "Accidents can occur due not only to reasons related to the aircraft, but to pilot error."
