A. General Information for Jacking
Subtask 07-12-00-210-050-A NOTE: If you deflate the 2 tires at the same time, the maximum closed height of the hydraulic jack must be 128 mm (5.04 in.). Use tool jack TMHCP07-00-00 or an equivalent.
B. Aircraft Configuration
(1) Make sure that the wheels are on the aircraft axis.
(2) Make sure that the aircraft is clear to lift.
(3) Make sure that the safety devices are installed on the landing gears (Ref. AMM TASK 32-00-00-481-001).
(4) Make sure that the parking brake is released.
(5) Make sure that the aircraft is stable before you lift the aircraft (Ref. AMM TASK 05-57-00-200-001).
(6) If you do ground operations (cargo loading/unloading, fueling/defueling, passenger boarding/disembarking) and jacking for a wheel change at the same time, you must:

- Make sure that the door sill and ground support equipment (cargo loader, passenger bridge and/or catering truck) stay aligned.
- Decrease the loading speed of the Unit Load Device (ULD) and make sure that the ULD smoothly touches the lateral stop of the Cargo Loading System (CLS).
- Make sure that the weight change is not more than 20000 kg (44092 lb).
C. Install the CHOCK - WHEEL(S) on the wheels of the main landing gears.
