An aircraft landing gear assembly (50, 80) comprising: a main strut arranged to be movably coupled to an aircraft to move between a deployed condition and a stowed condition; a side stay comprising a first stay member pivotally coupled to a second stay member, the first stay member being pivotally coupled to the main strut and the second stay member being arranged to be pivotally coupled to an anchor point so as to be movable between a locking condition in which the side stay members are generally aligned to react a force attempting to move the main strut from the deployed condition towards the stowed condition, and a passive condition in which the side stay permits the main strut to be moved from the deployed condition towards the stowed condition; a lock link comprising a first lock link member pivotally coupled to a second lock link member, the first lock link member being pivotally coupled to the main strut and the second stay member being pivotally coupled to the side stay so as to be movable between a locking condition in which the lock link members are generally aligned to react a force attempting to move the side stay from the locking condition towards the passive condition, and a passive condition in which the lock link permits the side stay to be moved from the locking condition towards the passive condition, a first landing gear element movably coupled relative to a second landing gear element to pivot about a pivot axis between a first condition and a second condition; and a leaf spring having a first end region and a second end region, the first end region of the leaf spring being coupled to the first landing gear element to move with the first landing gear element, characterised in that the landing gear assembly further comprises a cam surface defined by the second landing gear element, the second end region of the leaf spring comprising a cam follower arranged in moving contact with the cam surface such that the cam follower moves from a first region of the cam surface to a third region of the cam surface via a second region of the cam surface as the first landing gear element pivots about the pivot axis between the first condition and the second condition, wherein the cam surface is shaped such that a distance between the pivot axis and the cam surface increases between the first region and the second region to define a first gradient and the distance between the pivot axis and the cam surface varies between the second region and the third region of the cam surface to define a second gradient, the second gradient being less steep than the first gradient, wherein the first landing gear element comprises the first lock link member or the second lock link member. a main strut arranged to be movably coupled to an aircraft to move between a deployed condition and a stowed condition;
