SEQ 110
— GRAVITY GEAR EXTN handcrank PULL AND TURN
Rotate the handle clockwise 3 turns until reaching the mechanical stop, even if resistance is felt.
— L/G lever DOWN
— GEAR DOWN indications (if available) CHECK
NOTE: 1. Depending on aircraft speed, the display may show the landing gear doors in the amber transit position.
2. In the event of gravity extension caused by the failure of both LGCIUs, landing gear position indications on the ECAM are lost. LDG GEAR lights the ON LDG control panel remain available, if LGCIU1 is electrically-supplied.
3. The LGCIU 2 FAULT or BRAKES BSCU CH 1(2) FAULT warning may be spuriously triggered after a gravity extension.
4. If the three green downlock arrows are not on, it is possible that the handcrank is not at the mechanical stop. Check that the handcrank is firmly against the mechanical stop.
* If successful :
Do not reset the free-fall system : This will avoid such undesirable effects as further loss of fluid, in the event of a leak, or possible landing gear unlocking, in the event of a gear selector valve jamming in the UP position.
NOTE: The free-fall system may be reset in flights used for training. If the green hydraulic system is available, resetting the free-fall system allows the landing gear doors to be closed and the nosewheel steering to operate.
The flight crew should not reset the free-fall system on the ground after flight.
* If unsuccessful : — LDG WITH ABNORMAL L/G procedure APPLY
