The V-22 Osprey comes up short in desert testing

The last time we covered tilt-rotor aircraft, Bell Helicopter's TR918 Eagle Eye Unmanned Aircraft System (UAS) received its FAA certification. The Eagle Eye weighed in at around one ton and featured a top speed of 250MPH.

Today, a report shows that a much larger scale tilt-rotor vehicle from Bell-Boeing is running into more trouble. The Bell-Boeing V-22 Osprey has had a storied past including two prominent crashes during development that have killed a total of 23 Marines. These days, the Osprey is still getting flak for "poor aircraft availability" and "marginal operational availability" during 41 test flights this past summer.

The aircraft was lambasted in a recent annual report put forth by the U.S. Defense Department. "Frequent part and system failures, limited supply support, and high false alarm rates in the built-in diagnostic systems caused frequent flight delays and an excessive maintenance workload," claims the report.

Four Air Force CV-22 Osprey aircraft were assessed between June 6, 2006 and July, 10 2006 at Kirtland Air Force Base, NM. Many of the problems cited in the report stem from the aircraft's poor performance and serviceability in desert conditions. The Marine Corps version of the Osprey is likely to encounter similar performance and maintenance issues as the aircraft mainly differ in equipment packages offered.

The latest batch of issues is troubling to Philip Coyle, senior advisor for the Center for Defense Information. "This produces a maintenance and support burden that the Marines really can’t afford. All of the reliability problems that they continue to have here in the [United] States -- it’s going to drive them crazy overseas."

The V-22 Osprey has a maximum take-off weight of 47,500 pounds, a cruising speed of 246MPH and a top speed of 316MPH. The Air Force currently has plans to purchase 50 Ospreys while the Marine Corps has plans for 360 aircraft.

..C-17 had similar development problems although I don't reall any C-17 crashes during the development phase. C-17 is now one of the best heavy lift cargo craft in the world.

The C-17 is an outstanding transport, but, it definately has it fair share of issues. As the fleet is getting older, the reliability has dropped of the table. The bases which receieved the early 17's are now having problems keeping them in the air. That said, they do a great job replacing the 141 and allow the C-5 to better do it's job of the main heavy lifter for intercontinental travel while the 17 does theatre transport(for the most part).
