Airbus has adopted a completely new philosophy for the attachment of the A350 XWB’s main landing gear as part of the switch to a composite wing structure. Each XWB's main landing gear leg is going to be attached to the rear wing spar forward and to a gear beam aft, which itself is attached to the wing and the fuselage. To help reduce the loads further into the wing, a double side-stay configuration has been adopted. This solution resembles the design of the Vickers VC10. Airbus devised a three-pronged main landing gear design philosophy encompassing both four- and six-wheel bogies to ensure it can keep the pavement loading within limits. The A350-800 and A350-900 will both have four-wheel bogies, although the -800's will be slightly shorter to save weight. Both will fit in the same 4.1 m (13.5 ft) long bay. The proposed higher weight variant, the A350-1000, A350-900R (Airbus is offering BA a variant called the A350-900R, which will have a range of about 9,400 nautical miles. This would allow the airline to schedule direct Heathrow-to-Sydney flights.) and A350-900F will used a six-wheel bogey and a 4.7 m landing gear bay. French-based Messier-Dowty has been confirmed to be providing the main landing gear for the new XWB. The nose gear will be supplied by Liebherr-Aerospace.
