B. Aircraft Maintenance Configuration
(1)
Drain the standby air data system (Ref. TASK 12-24-34-600-001).
(2)
Disconnect the quick-disconnect coupling (4) from the ADM 19FP8 and the quick-disconnect coupling (8) from the ADM 19FP3.
(3)
Disconnect the cabin-pressure detection pressure-switch 14WN (3) from the static pipe. Put a blanking cap on the pressure switch.
(4)
Remove the water drain plug (2) from the water drain (1).
(5)
In the cockpit, on the center instrument panel:
-
remove the standby altimeter 3FN (Ref. TASK 34-21-22-000-001)
-
remove the standby airspeed indicator (6) 9FN (Ref. TASK 34-21-26-000-001)
-
remove the metric altimeter (15FN) (Ref. TASK 34-21-25-000-001).
(6)
Disconnect the quick-disconnect coupling (7) from the red 2-pin coupling of the standby airspeed indicator (6) and disconnect the quick-disconnect couplings (5) from the yellow 3-pin couplings of the standby instruments 3FN, 9FN and 15FN.
(7)
Connect a ADAPTERS - AIR DATA SYSTEM FLUSHING 3-pin adapter (98D34103002100) to the hose of the standby altimeter and a ADAPTERS-AIR DATA SYSTEM FLUSHING 2-pin adapter (98D34103002102) to the hose (7). Then connect them to the dry nitrogen source - 2 bars (29 psi).
