A retractable landing gear assembly for an aircraft has a main strut 210 arranged to pivot between a retracted position and an extended position, and a sidestay 220 having an unfolded position and a folded position. A telescopic actuator 250 is coupled between the main strut and the sidestay, so that when the actuator has a first length the sidestay locks the main strut in the extended position, and when the actuator has a second length the sidestay is in the folded position and the main strut is in the retracted position. There is also disclosed a retractable landing gear assembly comprising a foldable sidestay, an actuator arranged to provide an actuation force to retract the sidestay and lock the sidestay in the unfolded position. There is also disclosed a method of manufacturing a retractable landing gear assembly including coupling an actuator between first and second elements of the landing gear assembly, the actuator being arranged to retract the landing gear when in use on the aircraft, with the actuator coupled retracting and extending the landing gear assembly, and adjusting parameters and/or connections of the landing gear assembly prior to attaching it to the aircraft.
