Procedure

    1. SUBTASK 30-21-49-780-002 Prepare the Ducts (02-500 and 01-010) for the Hydraulic Pressure-Test

    1. Install the IAE 1N20415 Pressurizing adapter 1 off and the 206-368 dowty seal 1 off to the duct (01-010). Safety the components with an applicable aeroquip coupling.

    2. Install the IAE 1N20416 Blanking adapter 1 off and the 206-367 dowty seal 1 off to the duct (01-010). Safety the components with an applicable aeroquip coupling.

    3. Install the IAE 1N20417 Pressurizing adapter 1 off and the 206-356 dowty seal 1 off to the duct (02-500). Safety the components with an applicable aeroquip coupling.

    4. Install the IAE 1N20418 Blanking adapter 1 off and the 206-356 dowty seal 1 off to the duct (02-500). Safety the components with an applicable aeroquip coupling.

    2. SUBTASK 30-21-49-780-003 Do the Hydraulic Pressure Test of the Ducts (02-500 and 01-010)

    1. Connect the duct to the outlet of the Hydraulic pressure testing rig.

    2. Make sure that the bleed screw is at the highest position and open.

    3. Make sure that the pressure control valve is set to zero.

    5. Slowly turn the pressure control valve until the fluid comes out of the bleed screw.

    6. Close the bleed screw.

    7. 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.

      Increase the pressure in the ducts (01-010 and 02-500) to 225 psi (1551 kPa).

    8. Let the pressure stay in the duct for 2 minutes.

    9. 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.

    10. Decrease the pressure in the duct to zero.

    12. Open the bleed screw.

    13. Disconnect the duct from the outlet of the Hydraulic pressure testing rig.

    14. Remove the couplings, the adapters and the seals from the duct.

    15. 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.

    3. SUBTASK 30-21-49-780-004 Prepare the Ducts (01-010 and 02-500) for the Pneumatic Pressure Test

    1. Do again the procedure to prepare the duct for the hydraulic pressure test, refer to Step

    4. SUBTASK 30-21-49-780-005 Do the Pneumatic Pressure Test of the Ducts (02-500 and 01-010)

    1. Make sure that the bleed screw is closed.

    2. Connect the duct to the outlet of the Pneumatic pressure testing rig.

    3. Put a pressure of 14.5 psi (100 kPa) in the duct.

    4. Put the duct in the water tank.

    5. Let the pressure stay in the duct for 1 minute.

    6. 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.

    7. Decrease the pressure in the duct to zero.
