Procedure

    1. The Test Equipment Specification

    1. Refer to Figure and Figure.

    2. To do the test on the engine fuel tubes use equipment equivalent to that shown.

    2. SUBTASK 73-11-47-780-051 Prepare the Tube (01-100) for the Hydraulic Pressure Test

    1. Install the IAE 1N20430 Pressurising adapter 1 off and the AGS164/C fibre washer 1 off to the flange with 0.250 in. (6.4 mm) bolts, washers and nuts.

    3. SUBTASK 73-11-47-780-052 Prepare the Tube (02-100) for the Hydraulic Pressure Test

    1. Install the IAE 1N20431 Pressurising adapter 1 off and the AGS164/E fibre washer 1 off to the flange with 0.250 in. (6.4 mm) bolts, washers and nuts.

    4. SUBTASK 73-11-47-780-053 Do the Hydraulic Pressure Test on the Tubes (01-100 and 02-100)

    1. Connect the tube to the outlet of the Hydraulic pressure testing rig and the bleed valve adapter. Make sure that the bleed valve is open.

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

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

    5. Close the bleed valve.

    6. CAUTION

      DO NOT GO PAST THE TEST PRESSURE SHOWN BELOW. IT CAN CAUSE DAMAGE TO THE TUBE. IF THE PRESSURE IN THE TUBE GETS TO MORE THAN THAT SHOWN BELOW, REJECT THE TUBE.

      Increase the pressure in the tubes (01-100 and 02-100) to 500 psi (3450 kPa).

    7. Let the pressure stay in the tube for 2 minutes.

    8. Make sure that the tube has no leaks. If the tube has leaks, reject the tube, refer to Inspection-000 TASK 73-11-47-200-100.

    9. Decrease the pressure in the tube to zero.

    11. Open the bleed valve.

    12. Disconnect the tube from the outlet of the Hydraulic pressure testing rig and the bleed valve adapter.

    13. Remove the pressurizing adapter and the fibre washer.

    14. WARNING

      BE CAREFUL WHEN YOU USE COMPRESSED AIR. PUT ON PROTECTIVE CLOTHING AND GOGGLES.

      Remove unwanted fluid from the tube with clean, dry compressed air.

    5. SUBTASK 73-11-47-780-054 Prepare the Tube (01-100) for the Pneumatic Pressure Test

    1. Install the IAE 1N20430 Pressurising adapter 1 off and the AGS164/C fibre washer 1 off to the flange with 0.250 in. (6.4 mm) bolts, washers and nuts.

    2. Install an applicable Blanking plug to the tube.

    6. SUBTASK 73-11-47-780-055 Prepare the Tube (02-100) for the Pneumatic Pressure Test

    1. Install the IAE 1N20431 Pressurising adapter 1 off and the AGS164/E fibre washer 1 off to the flange with the 0.250 in. (6.4 mm) bolts, washers and nuts.

    2. Install an applicable Blanking plug to the tube.

    7. SUBTASK 73-11-47-780-056 Do the Pneumatic Pressure Test of the Tubes (01-100 and 02-200)

    1. Connect the tube to the outlet of the Pneumatic pressure testing rig.

    2. Put a pressure of 14.5 psi (110 kPa) in the tube.

    3. Put the tube in the water tank.

    4. Let the pressure stay in the tube for 1 minute.

    5. Make sure that the tube has no leaks. If the tube has leaks, reject the tube, refer to Inspection-000 TASK 73-11-47-200-100.

    6. Decrease the pressure in the tube to zero.

    7. Disconnect the tube from the outlet of the Pneumatic pressure testing rig.

    8. Remove the Blanking plug, the pressurizing adapter and the fibre washer from the tube.
