The U.S. military announced Wednesday the grounding of all its Osprey CV-22 aircraft, one week after eight Air Force Special Operations Command service members died in a crash off the coast of Japan.
Lt. Gen. Tony Bauernfeind, head of Air Force Special Operations Command, directed the grounding "to mitigate risk while the investigation continues," the command said in a statement.
The military said that the "standdown" of the Osprey CV-22 aircraft will "provide time and space" for a thorough investigation and to ensure a safe return to operations.
The extraordinary decision to ground the entire fleet of Ospreys came after a preliminary investigation revealed that a material failure was the cause of the devastating crash — not a mistake by the crew.

In a release, the Air Force Special Operations Command said that the underlying cause of the failure was still unknown at that time.
The military did not immediately say when the fleet would be back in commission.
Eight service members died during the devastating crash off the shore of Yakushima Island, Japan on Nov. 29.
On Tuesday, military officials identified the service members who were on board the Air Force CV-22 Osprey.
"Our thoughts and prayers are with the families, friends and peers of all who are impacted by this mishap and loss of life," said Bauernfeind. "In times like these, where service to our nation is not just a personal commitment but also a legacy woven into the fabric of our families, the depth of sorrow is immeasurable.
"The honorable service of these eight Airmen to this great Nation will never be forgotten, as they are now among the giants who shape our history."
