SUBTASK 30-21-49-780-051 Prepare the Ducts (01-070, 02-100, 02-500, 01-010 and 01-050) for the Hydraulic Pressure-Test
Connect the duct to the outlet of the Hydraulic pressure testing rig.
Make sure that the bleed screw is at the highest position and open.
Make sure that the pressure control valve is set to zero.
Start the Hydraulic pressure testing rig.
Slowly turn the pressure control valve until the fluid comes out of the bleed screw.
Close the bleed screw.

CAUTION
DO NOT GO PAST THE TEST PRESSURE SHOWN BELOW. IT CAN CAUSE DAMAGE TO THE DUCT. IF THE PRESSURE IN THE DUCT GETS TO MORE THAN THAT SHOWN BELOW, REJECT THE DUCT.Increse the pressure in the ducts (01-010, 01-050, 01-070, 02-100 and 02-500) to 195 psi (1345 kPa).
Let the pressure stay in the duct for 2 minutes.
Make sure that the duct has no leaks. If the duct has leaks, reject the duct, Refer to Inspection-000 TASK 30-21-49-200-100.
Decrease the pressure in the duct to zero.
Stop the Hydraulic pressure testing rig.
Open the bleed screw.
Disconnect the duct from the outlet of the Hydraulic pressure testing rig.
Remove the couplings, the adapters and the seals from the duct.

WARNING
BE CAREFUL WHEN YOU USE COMPRESSED AIR. PUT ON PROTECTIVE CLOTHING AND GOGGLES.Remove unwanted fluid from the duct with clean, dry compressed air.
SUBTASK 30-21-49-780-052 Do the Hydraulic Pressure Test of the Ducts (01-070, 02-100, 02-500, 01- 010 and 01-050)
Do again the procedure to prepare the duct for the hydraulic pressure test, refer to Step
SUBTASK 30-21-49-780-053 Prepare the Ducts (01-070, 02-100, 02-500, 01-010 and 01-050) for the Pneumatic Pressure Test
Make sure that the bleed screw is closed.
Connect the duct to the outlet of the Pneumatic pressure testing rig.
Put a pressure of 14.5 psi (100 kPa) in the duct.
Put the duct in the water tank.
Let the pressure stay in the duct for 1 minute.
Make sure that the duct has no leaks. If the duct has leaks, reject the duct, Refer to Inspection-000 TASK 30-21-49-200-100.
Decrease the pressure in the duct to zero.
Disconnect the duct from the outlet of the Pneumatic pressure testing rig.
Remove the couplings, the adapters and the seals from the duct.
SUBTASK 30-21-49-780-054 Do the Pneumatic Pressure Test of the Ducts (01-070, 01-100, 02-500, 01- 010 and 01-050)
