(1) Make sure that the green hydraulic system is depressurized.
Subtask 32-31-00-869-106
D. Flight Configuration Precautions
(1)
If the electrical power is not necessary for other maintenance tasks, de-energize the aircraft electrical circuits (Ref. TASK 24-41-00-862-002). Then, it is not necessary to operate the LGCIU circuit breakers.
(2)
If the electrical power is necessary, do the precautions for flight configuration (Ref. TASK 32-00-00-860-001) before you open the LGCIU circuit breakers.
