C. Test of the Outlet Non-Return Valve NOTE : Do a leak test on the outlet non-return valve (2) with the air
____ pressure supplied from both a ground supply and the low pressure air bleed. Do the test at the same time as the pressure is supplied.
(1)
Start the aircraft APU (Ref. TASK 49-00-00-860-008).
(2)
Make sure that the bleed air supply from the APU is set to supply the reservoir pressurizing system (Ref. TASK 36-12-00-710-001).
(3)
Apply SPECIAL MATERIALS (Material No. 05-004) to the these connections:
-The line (1) and the outlet non-return valve (2),
-the reservoir pressurization unit (3) and the outlet non-return valve (2).
(4)
Make sure that there is no leak.
(5)
Stop the operation of the aircraft APU (Ref. TASK 49-00-00-860-009).
(6) Pressurize the reservoirs of the Green, Blue and Yellow hydraulic
systems (Ref. TASK 29-14-00-614-002).
(7) Examine these connections and make sure that there is no leak:
- The line (1) and the outlet non-return valve (2),
- the reservoir pressurization unit (3) and the outlet non-return
valve (2).
