Auxiliary control of extension, retraction and pivotal movement of aircraft landing gear when not in use is provided by a method of operation, apparatus for attaching to the landing gear, and an assembly comprising landing gear and apparatus. The apparatus comprises auxiliary jacking means (18, 19) attachable between relatively telescopic parts of an oleo main strut of the landing gear and between relatively pivotal parts of the oleo and of a bogie pivotally attached to a lower end of the oleo. The landing gear may thus be powered up by the auxiliary jacking means (18, 19) with the pivotal movement of the bogie (4) being controlled simultaneously during, e.g. removal, fitting or servicing of the landing gear.
