Abstract

A temporary pintle support which can attach between upper prongs of a landing gear, and which is arranged to hold pintle pins prior to installation of the landing gear assembly at an aircraft. The pintle support is attached at the landing gear to align the pintle pins with their respective attachment bearings on each of the prongs. The pintle support may be removed once the pintle pins are fully inserted.

Claims (25)

1. A removable pintle support configured to engage with a landing gear assembly, to be supported by the landing gear assembly, and to support at least one pintle pin in a predetermined position with respect to at least one orifice of the landing gear assembly during installation of the landing gear assembly to an aircraft.

2. The pintle support of claim 1 , wherein the predetermined position is adjacent at least one orifice of the landing gear assembly, and wherein the pintle support is configured to support the at least one pintle pin in alignment with the at least one orifice.

3. The pintle support of claim 2 , wherein the pintle support is configured to support the or each pintle pin for insertion into, and or with at least one of the pins partially inserted in, the or each respective orifice, with the pintle support engaged with the landing gear assembly.

4. The pintle support of claim 1 , wherein the pintle support is configured to support forward and aft pintle pins in alignment with forward and aft orifices of the landing gear assembly respectively.

5. The pintle support of claim 4 , wherein the pintle support is configured to be engaged with the landing gear assembly between the forward and aft orifices of the landing gear assembly.

6. The pintle support of claim 5 , wherein the pintle support is configured to support the forward and or aft pintle pins for insertion into, and or with at least one of the pins partially inserted in, the forward and or aft orifices respectively, with the pintle support engaged with the landing gear assembly.

7. The pintle support of claim 1 , wherein the pintle support is fabricated from one of cardboard and plastics material.

8. The pintle support of claim 1 , wherein the pintle support is shaped to cradle the or each respective pintle pin, to thereby provide positional stability and or protection from contamination and surface damage.

9. A landing gear assembly configured to engage with and support a removable pintle support in a predetermined position relative to the landing gear assembly, thereby supporting at least one pintle pin in a predetermined position with respect to at least one pintle orifice of the landing gear assembly.

10. The landing gear assembly of claim 9 , wherein the landing gear assembly includes an engager comprising at least one protruding member configured to engage and support the pintle support in its predetermined position, thereby to support the or each pintle pin in alignment with the or each respective pintle orifice.

11. The landing gear assembly of claim 9 , wherein the landing gear assembly includes an engager comprising at least one recess configured to engage and support the pintle support in its predetermined position, thereby to support the or each pintle pin in alignment with the or each respective pintle orifice.

12. A method of installing a landing gear assembly at an aircraft, the method comprising:

engaging a pintle support to the landing gear assembly so that the pintle support is supported by the landing gear assembly in a predetermined position relative to an orifice of the landing gear assembly;

placing a pintle pin on the pintle support, in alignment with the orifice;

positioning the landing gear assembly at a landing gear fixing of the aircraft, with the orifice of the landing gear assembly in alignment with the landing gear fixing;

inserting the pintle pin into the orifice and the landing gear fixing to attach the landing gear assembly to the aircraft; and

after the pintle pin has been fully inserted into the orifice and the landing gear fixing, removing the pintle support from the landing gear assembly.

13. The method of claim 12 , further comprising, prior to positioning the landing gear assembly at the landing gear fixing of the aircraft, inserting the pintle pin into the orifice of the landing gear assembly.

14. The method of claim 12 , further comprising:

engaging the pintle support to the landing gear assembly so that the pintle support is supported in a predetermined position relative to a further orifice of the landing gear assembly;

placing a further pintle pin on the pintle support in alignment with the further orifice;

positioning the landing gear assembly at a landing gear fixing of the aircraft with both the orifice and the further orifice of the landing gear assembly in alignment with the landing gear fixing; and

inserting the pintle pin and the further pintle pin into the orifice and the further orifice respectively, and into the landing gear fixing, to attach the landing gear assembly to the aircraft.

15. The method of claim 14 , further comprising, prior to positioning the landing gear assembly at the landing gear fixing of the aircraft, inserting the further pintle pin into the further orifice of the landing gear assembly.

16. The method of claim 12 , further comprising removing the pintle support from the landing gear assembly, and providing the pintle support for use with another landing gear assembly to be installed at an aircraft.
