 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).
