The military announced late Wednesday it was grounding all of its Osprey V-22 helicopters, one week after eight Air Force Special Operations Command service members died in a crash off the coast of Japan.

The crash raised new questions about the safety of the Osprey, which has been involved in multiple fatal accidents over its relatively short time in service.
Japan grounded its fleet of 14 Ospreys after the crash.

Chief Cabinet Secretary Hirokazu Matsuno told reporters in Tokyo the government has already formally requested that the U.S. military ensure the safety of Ospreys before their flights, but that Tokyo will seek further information from the U.S. side because it also affects the safety of Japan’s own Osprey fleet.

“Needless to say, ensuring flight safety is the top priority of aircraft operation,” Matsuno said. “Japanese Self-Defense Force also operate Ospreys, and in order to ensure their flight safety, we will continue to ask the U.S. side to share information with us.”

In August, the Marines found that a fatal 2022 Osprey crash was caused by a clutch failure, but the root cause was still unknown. In its report on the crash, the Marines forewarned that future incidents “are impossible to prevent” without improvements to flight control system software, drivetrain component material strength, and robust inspection requirements.”

Air Force Special Operations Command has 51 Ospreys,
the U.S. Marine Corps flies as many as 400
and U.S. Navy operates 27.

Maybe the Japanese “with independent viewpoint” can figure out the “Hard Clutch Engagement” problem to keep their 14 safer.

This accident does not fit the earlier circumstances:

The Osprey, assigned to Yokota Air Base in Tokyo, was on a training flight when it crashed Nov. 29 off the southern Japanese island of Yakushima. It had departed from Marine Corps Air Station Iwakuni in Yamaguchi Prefecture and was headed to Kadena Air Base on Okinawa, but requested an emergency landing on Yakushima just before crashing off the shore.

Eyewitnesses said the aircraft flipped over and burst into flames before plunging into the ocean.
