Is the Osprey Safe?

The Bell-Boeing V-22 Osprey tilt-rotor plane is elevating renewed considerations – and even protests – over its security in Okinawa and elsewhere in Japan. This week, the U.S. army determined to floor its fleet of the transport plane following the deadly crash off southwest Japan of a CV-22 Osprey flying from Yokota Air Base in Tokyo, which killed eight crew members on board.

Though the Osprey has an extended historical past of accidents, the newest lethal crash in Japan turned the second-worst accident ever worldwide. The worst accident involving an Osprey occurred on April 8, 2000, when 19 Marines died throughout an operational take a look at at Marana Regional Airport within the U.S. state of Arizona.

On December 7, U.S. Pentagon Deputy press spokesperson Sabrina Singh mentioned that the choice to face down the entire Ospreys flown by the U.S. Marine Corps, Air Power, and Navy was “taken out of an abundance of warning” whereas the Air Power Particular Operations Command (AFSOC) conducts an investigation. 

The Osprey “is flexible, and its velocity and its vertical carry capabilities are usually not met by some other platform current in mounted or rotary-wing platforms, and so it’s an extremely helpful platform for all of our Providers to make use of,” Singh mentioned.

Nonetheless, it doesn’t matter what the Pentagon says, there have been 20 deaths in 4 crashes over the previous 20 months. That inevitably raises one easy query: Is the Osprey actually protected?

In keeping with the newest information from the Air Power Security Heart, the typical Class A mishap fee per 100,000 flight hours was 6.00 for the CV-22 in its lifetime as of December 2021. This accident fee is extraordinarily excessive in comparison with the U.S. Air Power’s total mishap fee of 1.35 for manned plane and a pair of.58 for unmanned plane as of September 2023.

Moreover, each Class A and Class B accidents for the CV-22 are literally on a rising pattern line over the previous 20 years, based on the Air Power Security Heart information.

Class A mishaps happen when there may be greater than $2.5 million in injury to the plane, the plane is destroyed, or its pilot or crewmember is killed or completely, completely disabled. In contrast, Class B mishaps happen when plane injury ranges from $600,000 to $2.5 million, a crewmember faces everlasting partial incapacity, or three or extra individuals are despatched to the hospital as a result of accident. 

At present, the U.S. Air Power has 51 CV-22s. In the meantime, the U.S. Marine Corps has some 400 MV-22s. The U.S. Navy has 27 CMV-22s. 

The web site of the U.S. Marine Corps in Okinawa introducing the MV-22 Osprey states that “The MV-22 is protected: it has a Class A mishap fee of three.27 per 100,000 flight hours since FY2010, on par with different Marine Corps aviation platforms.”

As well as, based on an accident report revealed in July 2023 after an MV-22 crashed into the California desert in June 2022, killing 5 crew members, the 10-year common mishap fee for the MV-22 is 3.16 per 100,000 flight hours. That is certainly on par with the USMC aviation mishap common of three.1, which incorporates plane such because the AV-8B, F/A-18A-C, F-35B, CH-53E, and KC-130J. This additionally implies that the MV-22 doesn’t have a security report that’s higher than USMC averages.

In keeping with Flightfax, a web based journal on aviation security revealed by the U.S. Military Fight Readiness Heart, the general Military manned plane Class A fee was 1.62 within the present fiscal yr, a lot decrease than MV-22’s and CV-22’s mishap charges. (The U.S. Military doesn’t use the Osprey in any respect.)

The truth that the V-22 is an costly plane that’s grounded typically is a serious motive why it nonetheless has few friends as we speak, though it was a revolutionary functionality when it first flew in 1989. The Osprey is an costly functionality that has discovered few consumers overseas – outdoors the USA, solely the Japan Floor Self-Protection Power (JGSDF) determined to obtain 17 V-22s. In the meantime, others which have proven curiosity – comparable to Australia, Indonesia, and Israel – in the end gave up on shopping for it. 

On December 6, the AFSOC commander mentioned in an announcement that preliminary investigation data on the crashed CV-22 off Japan indicated a possible materiel failure induced the mishap.

How lengthy Ospreys might be grounded around the globe will depend upon the outcomes of the AFSOC’s ongoing investigation into the reason for the accident. If a structural downside with the plane – comparable to a sprag clutch failure or a failure of the drive shaft that hyperlinks the Osprey’s two engines by working contained in the size of the wings – is discovered as a reason behind the deadly crash, there’s a risk that flights might be suspended for an prolonged time period.
