Source: CV-22 crash not caused by mechanical failure
By Stephen Trimble
The BellBoeing CV-22 crash in Afghanistan on 8 April was not caused by a mechanical failure, according to a source familiar with preliminary findings of the US military investigation.
The fatal crash, which killed four and injured others, occurred after the pilot lost situational awareness while landing in a wadi around 1am under brown-out conditions, the source says.
The incident killed the pilot, a flight engineer, an army Ranger and an unidentified civilian.
Air Force Special Operations Command (AFSOC), which owns the CV-22 fleet, was not immediately available to comment.
US military officials have previously stated the cause of the CV-22 crash in Afghanistan was still under investigation. Military spokesmen, however, have ruled out enemy fire as a potential cause.
The 8 August crash is the first fatal accident involving a V-22 Osprey tiltrotor since December 2000, and is the fifth fatal crash in the programme's chequered history.
In 2000, two fatal crashes within eight months caused by a combination of design flaws and mechanical failures forced military leaders to put the programme on hold for two years while contractors re-designed systems and the airframe to improve safety.
After declaring the MV-22 fleet operational in 2007, the US Marine Corps has deployed its version of the Osprey in Iraq and Afghanistan without suffering a fatal crash.
USMC officials have praised the MV-22's performance, although the service has acknowledged concerns about unexpectedly high costs to operate and maintain the unique tiltrotor fleet.
AFSOC, meanwhile, had deployed six CV-22s delivered so far to Africa, Iraq and Afghanistan before sustaining the crash.
The brown-out scenario during landing is recognized as a major safety concern for all rotorcraft operating in areas with loose sand. A recent study by the Office of the Secretary of Defense has concluded that 80% of the US millitary's 320 rotorcraft crashes during the last decade has been caused by degraded visual awareness.
que te `puedo decir tercios... pienso que es un muy buen producto pero altamente INMADURO para la actualidad militar.
Creo que deveria seguir su desarrollo... es cuestion de darle tiempo. Este sistema va a ser muy bueno operativamente hablando... pero necesita tiempo y tambien, lamentablemente, sangre.
Al Stuka le dijeron lo mismo, al Harrier tambien... y asi y todo dejaron su marca en la historia.
Me gustaria saber de Mario Ar a ver donde cornos esta... el seguro puede decir mucho de este sistema.
Saludos!
A powerful Congressman has called on the Marines to stop production on their controversial tiltrotor craft, the V-22 Osprey.
The Marine Corps’ leadership say they’re thrilled with how the Osprey has performed in Iraq — the aircraft’s first deployment, after nearly three decades in development. But critics say the aircraft still has a whole host of performance and safety issues; only about half of the fleet of 90 Ospreys are actually combat deployable. The cost per flight hour is over $11,000 — more than double the target estimate, according to a new Government Accountability Office report, presented at a hearing of the House Oversight and Government Reform Committee. Overall, the program has cost over $25 billion in research, development, production, and maintenance.
“Not only has the Osprey failed to live up to its initial billing, it has failed expensively,” declared committee chairman Ed Towns. “It’s time to put the Osprey out of its misery.”
Obviously, the Marine Corps disagree. And it’s not immediately clear what, if anything, Rep. Towns can do to stop the Marines They’re already halfway through production. The assembly line is efficient. Prices (while high) are stable. And they are working to fix some of the most egregious problems with the aircraft.

no creo que se pueda enfrentar ni incluso a un caza medio,no te digo nada contra un rafale o un EF,,,
y aqui los espertos sabran mejor de hasta que punto sera superior a un helo estilo tigre,(me refiero al ataque contra carro,etc,,,)
y si lo es,aun asi haria falta que el pais que lo ponga en esas labores deberia de tener el espacio aereo controlado,volviendo a lo mismo un bicho muy caro,para una labor que puede hacer varios helos,pienso que con la misma efectividad y mas barato.
No es un aparato de ataque, con lo que no puedes compararlo. Es como si me comparas un F-16 con un Hércules. Cada uno es muy bueno en lo suyo. Un Cobra, un Apache, un Tigretón, son aparatos muy buenos para el ataque, pero como medios de transporte son basura inútil. Pues lo mismo al Osprey, es un transporte de asalto, no un aparato de ataque.
A mi entender creo que ese es el mayor engaño que vendieron, es un transporte a secas, no un transporte de asalto. Luego de varios accidentes tuvieron que cambiarle los perfiles de descenso por unos muy suaves, incongruentes con bajar 20 marines en medio de la batalla; cualquier ametralladora o minigun tendria solo un estrecho arco de disparo a causa de que los motores en vertical la taparian; las condiciones donde puede hacer autorrotacion son irreales para un combate. Para mi, es un tipico avion politico, vendido, comprado y mantenido por gente que no va a ser la que se juegue el cuero a bordo de el.
