The army mentioned it had carried out an intensive investigation into final Wednesday’s accident and concluded that “the incident was brought on by human error”.
“The window in query is designed to be eliminated so as to help pilot egress in an emergency scenario. The suitable procedures for guaranteeing the window was secured weren’t accurately adopted,” added the army in a press release.
It once more apologised for what it known as a “regrettable” accident.
There have been no severe accidents from the window that landed at an elementary faculty close to the Futenma marine airbase on Okinawa island.
However the incident infuriated native residents, who’re already sad on the base being positioned so near their houses and colleges.
Residents need Futenma to be closed and a substitute constructed elsewhere in one other a part of Japan or abroad, saying they will now not dwell with the noise, accidents and occasional crimes dedicated by US service members.
“We attempt to be good members of the Okinawan neighborhood and to make sure the security of each our personnel and our neighborhood through which we dwell and serve,” mentioned the army assertion.
The accident got here simply two months after an American army helicopter burst into flames after touchdown in an empty subject in Okinawa.
