A. Aircraft Maintenance Configuration
(1) Make sure that the aircraft is in this configuration:
-the spoilers 1 thru 5 retracted,
-all servo controls in their neutral position.
4. Procedure_________
Subtask 29-10-00-220-051
A. Do this Functional Test
R R R (1) Use a ground service cart with a FLOWMETER 20 L.MN (5.2833 US GAL.MN), calibrated to +/- 1.5% over full range to pressurize the Blue hydraulic system (Ref. TASK 29-10-00-863-003).
(2) Make a record of the flow rate.
R (3) Make sure that the flow rate is not more than 7.5 l (1.9812 USgal)/minute.
(4) If the flow rate is too high, do the full check of internal leakage to find the cause (Ref. TASK 29-00-00-280-002).
5. Close-up________
Subtask 29-10-00-860-069
A. Put the aircraft back to the serviceable condition.
(1) Remove the ground service cart and the flow meter from the aircraft.
(2) Depressurize the Blue hydraulic system (Ref. TASK 29-10-00-864-003).
