Abstract: An aircraft landing gear 501 includes a folding side stay 502, wherein the folding side stay includes an integral locking mechanism and does not require the landing gear to include a lock stay. The lack of a lock stay reduces the airframe noise created by the aircraft, which is particularly significant when the aircraft is landing. The aircraft landing gear 501 is movable between an stowed and deployed position. The folding side stay 502 comprises a first section and a second section foldable relative to the first section. The integral locking mechanism 503 is arranged to lock the first section and second section of the folding side stay into position when the landing gear is in the deployed position.
