Leak Check of Engine Bleed Air Supply System and Packs Components with APU Bleed Air

TASK 36-11-00-720-005-A
Leak Check of Engine Bleed Air Supply System and Packs Components with APU Bleed Air

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.
WARNING: MAKE SURE THAT THE SAFETY DEVICES AND THE WARNING NOTICES ARE IN POSITION BEFORE YOU START A TASK ON OR NEAR:
  • THE FLIGHT CONTROLS
  • THE FLIGHT CONTROL SURFACES
  • THE LANDING GEAR AND RELATED DOORS
  • COMPONENTS THAT MOVE.
MOVEMENT OF COMPONENTS CAN KILL OR CAUSE INJURY TO PERSONS AND/OR DAMAGE TO EQUIPMENT.
ZONE: 210
1. Reason for the Job
To make sure that there are no leaks from the air bleed system downstream of the high-pressure bleed valve and intermediate-pressure bleed check-valve. Pressurization by APU and the bleed pressure regulator valve (PRV) test port.

Subtask 36-11-00-720-053-A ** ON A/C NOT FOR ALL
A. Functional Test of the Engine Bleed-Air-Supply System
   (1) Start APU:
     (a) After the APU starts, wait for a minimum of 3 minutes for the warm up period, before you select the APU BLEED.
   (2) In the cockpit, on AIR COND panel 30VU, push the APU BLEED pushbutton switch (the ON legend is on) to pressurize the bleed duct system.
The BLEED page shows that:
  • The CROSSBLEED valve is open
  • The APU bleed valve is open.
   (3) On the ECAM control panel:
  • Push the APU BLEED pushbutton switch (the APU page comes into the view on the lower ECAM display-unit and shows the APU BLEED pressure).
   (4) Do a leak test of the ducts of the bleed system (Ref. AMM TASK 36-22-00-790-001).
5. Close-up
