4. Procedure
_________ Subtask 49-16-00-710-052-A
A. Operational Test of the Air Intake Flap and Diverter NOTE : For adjustment of the air-intake flap (Ref. TASK 49-16-43-400-
____
003).
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1. On the overhead panel 25VU:
-push the APU MASTER SW pushbutton switch to the ON position.
2. On the ECAM panel:
-push the pushbutton APU.
3. Examine the contour of the air intake flap and the air intake structure.
On the overhead panel 25VU:
-
the ON legend in the APU MASTER SWpushbutton switch comes on.
-
the air intake flap opens.
On the ECAM systems page:
-
the FLAP OPEN indication comes on.
-
the contour should be in line. Themaximum deviation B of the flap is
1.0 mm (0.0393 in.).
NOTE : If the air intake flap is not in line with the structure, remove the
____ rubber cover on the lower part of the flap actuator rod for access. Disconnect the cotter pin, nut and the bolt that attaches the lower part of the actuator rod to the air intake flap. Adjust the actuator rod length to get the correct position.Then connect the actuator rod
to the air intake flap.
4. On the overhead panel 25VU:
-release the APU MASTER SW pushbutton to the off position.
5. Measure the clearance C between the air intake nose and the air intake flap.
On the overhead panel 25VU:
-
the ON legend in the APU MASTER SWpushbutton switch goes off.
-
the air intake flap closes.
-
the clearance C should be between 0.5mm (0.0196 in.) to 1.5 mm (0.0590in.) with the air intake flap
