Sir, I do not know the specifics of the V-22, because the aircraft was designed to meet a flight-hour life as opposed to a calendar-year life specification. The specification is 10,000 flight hours. We've already tested it to 20,000 flight hours. It's a composite airframe. There is no scheduled depot-level maintenance on the aircraft. So I would not think there would be an issue with 30 years, but I don't have the information, to give you an honest answer on that.
