LEAK DETECTION - INSPECTION/CHECK
_________________________________ TASK 36-22-00-790-001 Leak Check on all the Bleed Air Ducts
1. Reason for the Job
__________________
This procedure gives the general description of the leak check on all the bleed air ducts.
2. Job Set-up Information
______________________
A. Fixtures, Tools, Test and Support Equipment
-------------------------------------------------------------------------------REFERENCE QTY DESIGNATION -------------------------------------------------------------------------------
No specific distilled water No specific soap solution
B. Consumable Materials
-------------------------------------------------------------------------------REFERENCE DESIGNATION -------------------------------------------------------------------------------
Material No. 19-003 USA AMS 3819 LINT-FREE COTTON CLOTH (Ref. 20-31-00)
3. Job Set-up
__________ Subtask 36-22-00-860-051
A. Aircraft Maintenance Configuration
(1) To do a leak check, you can use two air sources:
-
Air source from the APU or
-
Air source from a ground air-supply unit. Use one of the two sources to do a leak check at the applicable connections.
4. Procedure
_________
Subtask 36-22-00-790-050
A. Leak Check on all the Bleed Air Ducts
(1) Use soap solution to do a leak check at the connections of the bleed air ducts (duct joint, flexible connections).
NOTE : Leaks are permitted if the soap solution stays on the joint
____ line with a continuous series of bubbles. This shows that the leaks are not important. Leaks are not permitted if the air pressure (from the air source) blows the soap solution off the joint line and prevents a continuous series of bubbles.
5. Close-up
________ Subtask 36-22-00-860-052
A. Put the aircraft back to its initial configuration.
(1) Use distilled water to remove all the soap solution from the ducts, and dry with MISCELLANEOUS (Material No. 19-003).
