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

TASK 36-11-00-720-804-A-01
Health Check Procedure - Pressure Regulation 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 functions of the EBAS.
The pressure regulation function contains the Bleed-Pressure Regulator Valve (PRV) (4001HA), the Bleed-Pressure-Regulator Valve Control-Solenoid (10HA) (referred in this procedure as the "PRV control solenoid") and the sense line that connects them.
The Bleed Health Check procedures contain a flow chart that can be used as instruction. This flow chart gives a visual idea of the procedure.
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.
