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).
(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 and 9FN.
(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 to the dry nitrogen source - 2 bars (29 psi).
(8) Attach the hoses to prevent movement.

A. Draining and Flushing of the Standby Static and the Standby Total Pressure Lines
(1) Blow the gas into each of the instrument hoses (5) and into the hose (7), from one to the other, at a pressure of 2 bars (29 psi). Do this for approximately 5 minutes.
(2) Put the pneumatic cleaner pitot adapter on the draining hole of the pitot probe 3 and blow the gas for approximately 30 seconds.

(3)
Make sure that there is no contamination in the pressurized gas at these outlets:
-L static probe 3 and R static probe 3
-Pitot probe 3
-Water drain
-Pipe of the cabin-pressure detection pressure-switch.
(4)
Put an ADAPTER COVER-STATIC PORT on the L static probe 3 then on the R static probe 3.
(5)
Make sure that the flow of gas is correct at :
-
the pipe of the pressure switch
-
the water drain.
(6)
Stop the flow of gas.
