D. Aircraft Maintenance Configuration
(1) Make sure that the Green hydraulic system is depressurized and put it in the maintenance configuration. (Ref. TASK 29-00-00-864-001)
(2) Depressurize the reservoir of the Green hydraulic system. (Ref. TASK 29-14-00-614-001)
(3) Depressurize the nose gear shock absorber. To do this act on the charging valve at the top of the shock absorber, as follows:
(a) Remove the blanking cap from the charging valve.
(b) Slowly open the valve by one and a half turns maximum.
(4) Lift the aircraft with jacks (Ref. TASK 07-11-00-581-001).
(5) Use a spatula to remove sealants from the mechanicals parts.
