The deal is part of Airbus' plan to restructure its activities to focus on core activities. For the A350, for example, around 50 per cent of the aero-structures work will be outsourced to partners.
Spirit AeroSystems will produce the composite fuselage structure in a new facility to be built in North Carolina.
With a range of up to 8,300nm/15,400 km, the A350 XWB (Xtra Wide-Body) family is available in three basic passenger versions: the A350-800 accommodating 270 passengers, the A350-900 seating 314, and the A350-1000 for 350 passengers.
The A350 is powered by two Rolls-Royce Trent XWB engines delivering each up to 92,000 pounds of thrust.
