TASK 36-11-53-720-802-A
Functional Test of the Overpressure Valve with the Bleed Test Set P/N 98D36109001000


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: YOU MUST NOT TOUCH HOT PARTS WITHOUT APPLICABLE GLOVES. HOT PARTS CAN CAUSE AN INJURY.
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.
WARNING: BEFORE YOU INSTALL/REMOVE THE GSE TOOL, READ THE MANUFACTURER'S INSTRUCTIONS, AND, WHILE YOU OPERATE THIS TOOL, CAREFULLY OBEY THEM. IF YOU DO NOT DO THIS, INJURY TO PERSONS AND DAMAGE TO EQUIPMENT CAN OCCUR.
WARNING: BE CAREFUL WHEN YOU USE CONSUMABLE MATERIALS. OBEY THE MATERIAL MANUFACTURER'S INSTRUCTIONS AND YOUR LOCAL REGULATIONS.
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.

4. Procedure
Subtask 36-11-53-480-056-A ** ON A/C NOT FOR ALL
A. Preparation for the Functional Test
   (1) Removal of the lockwire.
WARNING: USE PROTECTIVE GOGGLES AND GLOVES WHEN YOU REMOVE OR INSTALL LOCKWIRE. EACH TIME YOU CUT LOCKWIRE, REMOVE AND DISCARD IT IMMEDIATELY. LOOSE LOCKWIRE CAN CUT YOU OR MAKE YOU BLIND, AND/OR CAN CAUSE DAMAGE.
     (a) Remove the lockwire from the blanking plug of the OPV.
   (2) Remove the blanking plug from the test port.
   (3) Connect manually the 98D36109001000 TEST SET-EBAS,BLEED to the test port of the OPV.
   (4) Close the shutoff valve, the purge valve and the pressure regulator valve on the 98D36109001000 TEST SET-EBAS,BLEED.
NOTE: If the air cylinder has a regulator valve, it is not necessary to install the primary regulator valve supplied with the test set.
   (5) Connect manually the AIR SOURCE - REGULATED, FILTERED, DRY to the 98D36109001000 TEST SET-EBAS,BLEED.
   (6) Set the digital pressure gage to zero.

B. Functional Test of the OPV 5HA1 (5HA2) with the Test Set - Engine Bleed System
   (1) Do this test:
ACTION
RESULT
1.On the AIR SOURCE - REGULATED, FILTERED, DRY:
  • Open the shutoff valve.
On the AIR SOURCE - REGULATED, FILTERED, DRY:
  • The cylinder pressure gage shows the pressure.
2.On the AIR SOURCE - REGULATED, FILTERED, DRY:
  • Use the primary regulator to pressurize to 100 psi (6.89 bar).
On the AIR SOURCE - REGULATED, FILTERED, DRY:
  • The primary gage shows 100 psi (6.89 bar).
3.On the 98D36109001000 TEST SET-EBAS,BLEED:
  • Slowly pressurize the system to get a pressure value of 90 psi (6.21 bar).
On OPV 5HA1 (5HA2):
  • Make sure that the visual position shows that OPV 5HA1 (5HA2) is closed.
4.On the 98D36109001000 TEST SET-EBAS,BLEED:
  • Slowly depressurize the system to open the overpressure valve.
On the 98D36109001000 TEST SET-EBAS,BLEED, read the pressure gage:
  • When the pressure is less than 43 psi (2.96 bar) the visual position shows that OPV 5HA1 (5HA2) open.
5.On the 98D36109001000 TEST SET-EBAS,BLEED:
  • Depressurize the system.
On OPV 5HA1 (5HA2):
  • The visual position shows that OPV 5HA1 (5HA2) is open.
6.Depressurize the AIR SOURCE - REGULATED, FILTERED, DRY, and close the shutoff valve.

   (5) Disconnect the air cylinder from the 98D36109001000 TEST SET-EBAS,BLEED.
   (6) Installation of the blanking plug on the test port.
     (a) Install the blanking plug on the test port of the Over Pressure Valve.
     (b) TORQUE the blanking plug of the test port to between 0.5 and 0.4 m.daN (44.25 and 35.40 lbf.in ) T.
   (7) Installation of the lockwire.
WARNING: USE PROTECTIVE GOGGLES AND GLOVES WHEN YOU REMOVE OR INSTALL LOCKWIRE. EACH TIME YOU CUT LOCKWIRE, REMOVE AND DISCARD IT IMMEDIATELY. LOOSE LOCKWIRE CAN CUT YOU OR MAKE YOU BLIND, AND/OR CAN CAUSE DAMAGE.
