Retraction of a landing gear assembly (4, fig 3) on an aircraft (1, fig 3) is actuated by a hydraulic actuator 12. The actuator 12 includes a piston 28 that travels within a cylinder 26 along a stroke length between a first position corresponding to the landing gear assembly when extended and a second position corresponding to the landing gear assembly when retracted. Movement of the piston 28 along its stroke length is snubbed at different levels, for example by use of a snubbing spear 40 having one or more fluid channels 46, 48 formed herein. Differential snubbing is thus provided, which enables the landing gear to retract faster.
