B. Aircraft configuration
(1)
Put the safety barriers and the warning notices in position to keep persons out of the work area.
(2)
Make sure that the static probe covers are not installed.
(3)
Energize the aircraft electrical circuits (Ref. TASK 24-41-00-861-002).
(4)
Make sure that the avionics equipment ventilation operates correctly. NOTE : if during this test, the avionics equipment ventilation stops,
____
you must stop the test.
(5)
In the avionics compartment:
(a)
Put the safety plug - ref MS21913-4 with its O-ring - ref NAS1612-4 on the air inlet of the pressure switch 16WR.
(b)
Put a safety streamer on the safety plug.
(6)
We recommend that you remove the crew oxygen masks (Ref. TASK 35-12-41-000-002)
NOTE : This test requires an absolute pressure higher than the cabin
____ pressures you get during usual aircraft operations.
The crew masks have an aneroid capsule that is usually resistant to the absolute pressures you can get during this test. But, to prevent high stress on the aneroid capsule, we recommend the removal of the crew oxygen masks.
