B. Do a Check of the Filters in the Green Hydraulic System
(1)
For the low pressure (return) filter (1002GM):
(a)
Make sure that the red indicator button is not out. If the red indicator button is out, do these steps:
-push the red indicator button to set it again
-do an operational test of the Green hydraulic system (Ref. TASK 29-11-00-710-001).
(b)
If the red indicator button is out (after the operational test), replace the filter element (Ref. TASK 29-11-44-610-001).
(2)
For the water separator filter:
(a)
Make sure that the red indicator button is not out. If the red indicator button is out, do these steps:
-push the red indicator button to set it again
-do a functional test of the pressurizing system for the reservoirs (Ref. TASK 29-14-00-720-001).
(b)
If the red indicator button is out (after the functional test), replace the filter element (Ref. TASK 29-14-42-000-002) and (Ref. TASK 29-14-42-400-002).
(c)
If the red indicator button is not out (after the functional test), do one more check of the clogging indicator. Do this check after the aircraft returns to the main base. If the red indicator button is out, replace the filter assembly (Ref. TASK 29-14-42-000-002) and (Ref. TASK 29-14-42-400-002).
(3)
For the (ground service) filter (1132GM):
(a)
Make sure that the red indicator button is not out. If the red indicator button is out, do these steps:
-push the red indicator button to set it again
-do a test of the filling system (Ref. TASK 29-16-11-610-001).
(b)
If the red indicator button is out (after the test), replace the filter element (Ref. TASK 29-16-11-610-001).
(c)
If the red indicator button is not out (after the test), do one more check of the clogging indicator. Do this check after the aircraft returns to the main base. If the red indicator button is out, replace the filter assembly (Ref. TASK 29-16-11-610-001).

R R R (c) If the red indicator button is not out (after the operational test), do one more check of the clogging indicator. Do this check after the aircraft returns to the main base. If the red indicator button is out, replace the clogging indicator (Ref. TASK 29-11-44-960-001).
(2) For the high pressure (delivery) filter (1048GM):
(a) Make sure that the red indicator button is not out. If the red indicator button is out, do these steps: - push the red indicator button to set it again - do an operational test of the Green hydraulic system (Ref. TASK 29-11-00-710-001).
R (b) If the red indicator button is out (after the operational test), replace the filter element (Ref. TASK 29-11-45-610-001).
R R R (c) If the red indicator button is not out (after the operational test), do one more check of the clogging indicator. Do this check after the aircraft returns to the main base. If the red indicator button is out, replace the clogging indicator (Ref. TASK 29-11-45-960-001).

C. Do a Check of the Filters in the Blue Hydraulic System
(1) For the case drain filter (2084GM) of the electric pump:
(a) Make sure that the red indicator button is not out. If the red indicator button is out, do these steps: - push the red indicator button to set it again - do an operational test of the Blue hydraulic system (Ref. TASK 29-12-00-710-001).
R R R R (b) If the red indicator button is out (after the operational test), replace the filter element (Ref. TASK 29-12-43-610-001). If there are metal particles in the case drain filter, replace the Blue electric pump (Ref. TASK 29-12-51-000-001) (Ref. TASK 29-12-51-400-001).
R R (c) If the red indicator button is not out (after the operational test), do one more check of the clogging indicator. Do this check after the aircraft returns to the main base. If the red indicator button is out, replace the filter assembly (Ref. TASK 29-12-43-610-001). If there are metal particles in the case drain filter, replace the Blue electric pump.
(2) For the low pressure (return) filter (2002GM):
R (a) Make sure that the red indicator button is not out. If the red indicator button is out, do these steps: - push the red indicator button to set it again - do an operational test of the Blue hydraulic system (Ref. TASK 29-12-00-710-001).
R (b) If the red indicator button is out (after the operational test), replace the filter element (Ref. TASK 29-12-44-610-001).
