Aircraft
Aircraft means, unless otherwise provided in the contract Schedule, any item, other than a rocket or missile, intended for flight (e.g., fixed-winged aircraft, blended wing/lifting bodies, helicopters, vertical take-off or landing aircraft, lighter-than-air airships, and unmanned aerial vehicles), including emerging technologies that would commonly be considered aircraft. New production articles become aircraft at a stage of manufacture or production when a wing, portion of a wing, or engine is attached to a fuselage. Blended wing/lifting bodies become aircraft at a stage of manufacture or production when the center portion and a lifting surface become attached.
