Aircraft landing gear assembly stop member

1. An aircraft landing gear assembly stop member arranged to be coupled to an aircraft landing gear assembly prior to installation of the aircraft landing gear assembly into an aircraft and removed from the aircraft landing gear assembly once the aircraft landing gear assembly is installed in the aircraft, the stop member being arranged to limit movement of a first part of the aircraft landing gear assembly relative to a second part of the aircraft landing gear assembly, the stop member comprising:

an engagement formation via which the stop member can be removably coupled to the first part of the aircraft landing gear assembly to be placed in a coupled condition; and

first and second projections which when the stop member is in the coupled condition reside within a movement space corresponding to a volume swept by the second part as the second part moves relative to the first part throughout its total movement envelope, the projections being spaced from one another within the movement space so as to define an unobstructed portion of the movement space between them within which the second part is free to move, each projection being arranged to inhibit movement of the second part beyond it so as to confine the second part to the unobstructed portion of the movement space.

2. An aircraft landing gear assembly stop member according to claim 1 , comprising a recessed passage surface between the projections defining the unobstructed portion of the movement space.

3. An aircraft landing gear assembly stop member according to claim 1 , wherein one or more of the projections each define a gradient surface extending into the movement space so as to provide an increasing level of resistance to movement of the second part from the unobstructed portion of the movement space.

4. An aircraft landing gear assembly stop member according to claim 1 , wherein the first part is pivotally coupled to the second part.

5. An aircraft landing gear assembly stop member according to claim 1 , wherein the first part is arranged to move relative to the second part in a single movement plane.

6. An aircraft landing gear assembly stop member according to claim 1 , wherein the engagement formation of the stop member is arranged to conform to an external surface profile of one or more portions of the first part.

7. An aircraft landing gear assembly stop member according to claim 1 , wherein the first part comprises a stay member.

8. An aircraft landing gear assembly stop member according to claim 7 , wherein the second part comprises a cardan pin pivotally coupled to the stay member.

9. An aircraft landing gear assembly stop member according to claim 7 , wherein the stop member is provided with a hole positioned so as to align with a mounting lug for a down lock spring when the stop member is in the coupled condition.

10. An aircraft landing gear assembly stop member according to claim 1 , wherein the stop member includes a movable locking tab having an unlocked position in which the stop member can be moved to and from the coupled condition, and a locked condition which inhibits uncoupling of the stop member from the coupled condition.

11. An aircraft landing gear assembly comprising:

an aircraft landing gear assembly stop member coupled to the aircraft landing gear assembly prior to installation of the aircraft landing gear assembly into an aircraft and arranged to be removed from the aircraft landing gear assembly once the aircraft landing gear assembly is installed in the aircraft, the stop member being arranged to limit movement of a first part of the aircraft landing gear assembly relative to a second part of the aircraft landing gear assembly, the stop member comprising:

an engagement formation via which the stop member is removably coupled to the first part of the aircraft landing gear assembly to be placed in a coupled condition; and

first and second projections which when the stop member is in the coupled condition reside within a movement space corresponding to a volume swept by the second part as the second part moves relative to the first part throughout its total movement envelope, the projections being spaced from one another within the movement space so as to define an unobstructed portion of the movement space between them within which the second part is free to move, each projection being arranged to inhibit movement of the second part beyond it so as to confine the second part to the unobstructed portion of the movement space.

12. A method of forming an aircraft landing gear assembly comprising the step of coupling a stop member according to claim 1 to a first part of an aircraft landing gear assembly.
