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.
