Fatal crash of US Marines’ Osprey in Norway blamed on pilot error

The Air Force Special Operations Command has grounded all 52 of its CV-22 Ospreys because of an issue with the clutch that controls the distribution of power between the engines and rotors. The AFSOC says there have been two incidents in the last six weeks making a total of four in the last five years in which the clutches slipped and caused asymmetrical power distribution to the rotors. None of the aircraft involved crashed, but there have been some hairy moments and the Air Force credits the “skill and professionalism of our Air Commandos who operate the CV-22.”

When the clutches slip, they sometimes reengage, which throws power back the other way, and “if the aircrew were unable to control the aircraft when the incident occurs, it could result in loss of control and uncontrolled landing of the aircraft,” Lt. Col. Becky Heyse told Breaking Defense. “The safety of our Airmen is of the utmost importance, therefore no AFSOC CV-22s will fly until we will determine the cause of the hard clutch engagements and risk control measures are put in place.” It’s not clear how long the tiltrotors will be grounded. The Navy and Marines operate hundreds of the aircraft but there has been no similar announcement from those branches.

B.S, blame the overly complex POS osprey and the mic that fielded it. Dead pilots are difficult to interview to say what went wrong yet all to often are assigned the guilt! All the streets around EAFB are named after dead test pilots.

"Analysis of the recovered aircraft data showed that while in the valley, the Osprey made a left turn at 68 degrees angle of bank, followed by an over corrected right turn of more than 80 degrees, the Marines said."

How about the possibility of a powerplant or hydraulics fail as they have been known for, since the USMC and training designees had already trained him on the bank angle limits!

Sounds much more like mechanical fail in a mechanical fail prone aircraft than pilot error!

and, BTB, a 5,000 PSI hydraulic fail, leak will sever anything in its path as rapidly as a plasma cutter.

5000psi hydralics??? That thing must be prone to leaks?

Wow what a deal guess you should head all accident investigations. And by the way what mic are you talking about was there some radio chatter durning the crash. And most of all always blame the mechanic we are always at fault never the pilot.

I don’t see any blaming of the mechanic in this post, nor a high frequency in NTSB reports.I think he was referring to a known system issue that might explain the flight anomalies.

You will see no NTSB reports on military accidents unless there is a tangential connection to civilian transport ops. IE charters for military service members.

A military aviation accident investigation, MAAI, sans some form of commercial ops. involvement is completely divorced from civil aircraft accident investigators, IE FAA, NTSB.

IE, the military will blame anyone but the MIC!

Some punctuation would be awesome. Might almost make this comment readable.

Every time I hear of an Osprey crash I am reminded of the coverup at the beginning of this century that led to top generals at the Pentagon.

..I personally think this is one of the sketchyist (sic) AC in the sky today...however, a close USMC friend says it's the greatest AC he's ever flown and was complete confidence in it...

The V22 is one program that was cancel-proof. I remember in the early days when it seemed like fatal crashes were kinda common. I kept expecting it to get cancelled but it never did.

They should be grounded permanently.

I agree 100% and am sorry I failed to extend condolences in my previous post.

I seem to remember hearing a lot of the same rhetoric about the AV-8 Harrier when it first came out. It was “too complex, too dangerous”. There were numerous fatal accidents. The British did a lot better with it than the Americans and it played a huge part in winning the Falklands war. I don’t have the stats at hand but a big difference is that the Harrier only killed one or two at a time. The Osprey can kill dozens.

We can go all the way b ack to WW II. The Americans had a plane similar to the B25 which was the A26. Its nickname was the Widowmaker. And the people it killed the most were its own crews.

Until Jimmy Doolittle demonstrated to A-26 crews how to handle an engine failure during takeoff.

Umm, me thinks you guys have your airplane types mixed up. The "Widowmaker" handle was used to describe the Martin B-26 Marauder, not the A-26 Invader manufactured by the Douglas Aircraft Company.

"For a time in 1942, pilots in training believed that the B-26 could not be flown on one engine. This was disproved by several experienced pilots, including Colonel Jimmy Doolittle, who flew demonstration flights at MacDill Army Air Field, which featured take offs and landings with only one engine. Also, seventeen Women Airforce Service Pilots were trained to demonstrate the B-26, in an attempt to "shame" male pilots into the air."

"The Pratt & Whitney R-2800-5 engines were reliable, but the Curtiss electric pitch change mechanism in the propellers required impeccable maintenance, not always attainable in the field." Another issue at rollout and corrected by replacing same with Hamilton standard hydraulic props on later production aircraft.
