A landing gear assembly comprising: a first elongate member; a second elongate member movably coupled to the first elongate member; and a spring coupled to the first elongate member via an anchor and movably coupled to the second elongate member via a lost motion assembly (30, 31), characterised by the lost motion assembly comprising: a rod coupled to the second elongate member so as to move with the second elongate member; a shackle coupled to the spring and arranged to clasp the rod so as to be slidably coupled thereto; and first and second end stops (35, 37) arranged to limit travel of the shackle along the rod, thereby defining respective first and second travel limit points on the longitudinal axis of the rod, wherein the lost motion assembly is arranged such that: with the first elongate member at a first angular position with respect to the second elongate member, the distance between the first travel limit point and the anchor is less than the distance between the second travel limit point and the anchor; and with the first elongate member at a second angular position with respect to the second elongate member that is distinct from the first angular position, the distance between the first travel limit point and the anchor is greater than the distance between the second travel limit point and the anchor. a first elongate member; a second elongate member movably coupled to the first elongate member; and a spring coupled to the first elongate member via an anchor and movably coupled to the second elongate member via a lost motion assembly (30, 31), characterised by the lost motion assembly comprising: a rod coupled to the second elongate member so as to move with the second elongate member; a shackle coupled to the spring and arranged to clasp the rod so as to be slidably coupled thereto; and first and second end stops (35, 37) arranged to limit travel of the shackle along the rod, thereby defining respective first and second travel limit points on the longitudinal axis of the rod, a rod coupled to the second elongate member so as to move with the second elongate member; a shackle coupled to the spring and arranged to clasp the rod so as to be slidably coupled thereto; and first and second end stops (35, 37) arranged to limit travel of the shackle along the rod, thereby defining respective first and second travel limit points on the longitudinal axis of the rod, wherein the lost motion assembly is arranged such that: with the first elongate member at a first angular position with respect to the second elongate member, the distance between the first travel limit point and the anchor is less than the distance between the second travel limit point and the anchor; and with the first elongate member at a second angular position with respect to the second elongate member that is distinct from the first angular position, the distance between the first travel limit point and the anchor is greater than the distance between the second travel limit point and the anchor. with the first elongate member at a first angular position with respect to the second elongate member, the distance between the first travel limit point and the anchor is less than the distance between the second travel limit point and the anchor; and with the first elongate member at a second angular position with respect to the second elongate member that is distinct from the first angular position, the distance between the first travel limit point and the anchor is greater than the distance between the second travel limit point and the anchor.
