Health Check Procedure - Pressure Control Function with the Bleed Test Set P/N 98L36103002000

TASK 36-11-00-720-806-A-01
Health Check Procedure - Pressure Control Function with the Bleed Test Set P/N 98L36103002000

WARNING: MAKE SURE THAT THE PNEUMATIC SYSTEM IS DEPRESSURIZED BEFORE YOU START WORK. PRESSURIZED AIR CAN CAUSE INJURY TO PERSONNEL.
WARNING: BE CAREFUL WHEN YOU DO WORK ON THE ENGINE PARTS AFTER THE ENGINE SHUTDOWN. USE APPLICABLE THERMAL GLOVES. THE ENGINE PARTS CAN STAY HOT FOR ONE HOUR AFTER SHUTDOWN AND CAN BURN YOU.
NOTE: In the Health Check Procedures the electrical harness is in serviceable condition.
1. Reason for the Job
The Bleed Health Check procedure has a set of steps to do in order to first check the three primary functions of the EBAS.
  • For A/C with HPV SOL valve 11HA:
    The pressure control function contains the High Pressure Bleed Valve (HPV) (4000HA), the High Pressure Valve Control Solenoid (11HA) (referred to in this procedure as HPV solenoid valve) and the sense line that connects them with the Pressure Regulation Valve (PRV) (4001HA).
  • For A/C with HPV SOL Valve 4029KS:
    The pressure control function contains the HPV (4000HA), the High Pressure Valve Control Solenoid (4029KS) (referred to in this procedure as HPV solenoid valve) and the sense line that connects them with the PRV (4001HA).
  • For A/C without HPV SOL Valve:
    The pressure control function contains the HPV (4000HA) and the sense line that connects it with the PRV (4001HA).
    The pressure control function of the bleed system contains a flow chart that can be used as instruction. This flow chart gives a visual idea of the procedure.
    In order to make easy the maintenance step sequence and to prevent maintenance procedures that are not necessary, each AMM task has the structure of a special flow chart.
    It is not necessary to test all components if the first test at function level is satisfactory. Also, sense line installation can be damaged during disconnection-reconnection for testing, and a systematic test of the sense line is not recommended. Leakage test at sense line level is mandatory only if the troubleshooting is necessary.
    The operator can remove the components that have a drift, as given in the applicable flow chart, immediately or at the next maintenance unless there is an EWD message and the source of the CLASS1 failure is the component that has the drift. In this condition, you must refer to the MMEL/TSM for the aircraft dispatch.

P. Installation of the Tool for the Test of the HPV Solenoid Valve
   (1) For HPV with the deactivation screw on the regulator.
F Functional Test of the Sense Line between the HP Bleed Valve (with the Deactivation Screw on the Regulator) and the Bleed-Pressure Regulator Valve ** ON A/C NOT FOR ALL
     (a) Close the shutoff valve, the purge valve and the pressure regulator valve on the 98L36103002000 TEST SET - ENGINE BLEED (Z01).
WARNING: MAKE SURE THAT THE PRESSURE SUPPLIED TO BLEED TEST SET 98L36103002000 NEVER EXCEEDS 217 PSI (15 BAR). IF THE PRESSURE SUPPLIED TO THE BLEED TEST SET EXCEEDS THIS VALUE, THERE IS A RISK OF INJURY TO PERSONNEL AND DAMAGE TO EQUIPMENT. IF THE AIR CYLINDER DOES NOT HAVE A MANOMETER INSTALLED, YOU MUST INSTALL THE PRIMARY REGULATOR VALVE BETWEEN THE AIR BOTTLE AND BLEED TEST SET 98L36103002000. THE PRIMARY REGULATOR VALVE WILL LIMIT THE PRESSURE IN THE BLEED TEST SET TO 217 PSI (15 BAR).
     (b) Connect the AIR SOURCE 6.9 BAR (100 PSI) - REGULATED,FILTERED, DRY (Z03) to the 98L36103002000 TEST SET - ENGINE BLEED (Z01).

     (c) Connection of the 98L36103002000 TEST SET - ENGINE BLEED (Z01):
CAUTION: BE CAREFUL WHEN YOU CONNECT/DISCONNECT THE TEST SET TO/FROM THE EQUIPMENT. THE PRESSURE REGULATING VALVE AND THE PRESSURE GAGE ASSEMBLY OF THE TEST SET ARE HEAVY AND CAN CAUSE DAMAGE TO THE ENGINE.
       1 Connect the 98L36103002000 TEST SET - ENGINE BLEED (Z01) to the SBE2213 KIT TOOL-TESTER SENSE LINE (Z02).
     (d) Connect the GAGE - ABSOLUTE PRESSURE, DIGITAL, 0.001 BAR ACCURACY 2 to the valve 2 port of the sense line tester (T01) with the adaptor (T04).
     (e) TORQUE the adaptor (T04) to between 1.1 and 0.9 m.daN (97.35 and 79.65 lbf.in ) T.
     (f) Removal of the deactivation screw lockwire:
