WARNING: MAKE SURE THAT YOU OPEN, SAFETY, AND TAG THE CIRCUIT BREAKER FOR
THE PITOT HEAD HEATER. THE PITOT HEAD CAN GET VERY HOT AND CAUSE
BURNS.

4. Procedure
Refer to Figure 706
A. Do the pilot S2/copilot S1 static line contamination removal as follows:
CAUTION: MAKE SURE THAT THE PITOT AND/OR STATIC LINES ARE
DISCONNECTED FROM THE AIRCRAFT EQUIPMENT. IF THE LINES ARE
NOT DISCONNECTED, DAMAGE TO THE EQUIPMENT WILL OCCUR WHEN
PRESSURIZED NITROGEN IS SUPPLIED.
(1) Disconnect the static connector from the ADC 2.
(2) Install a cap on the static connector on the ADC 2.
(3) Remove the drain collector tubes from the static line drains that follow:
NOTE: The drain collector tube is attached to the drain assembly with a
quick−disconnect connector.
– S2/S1 drain assembly on the ADC 2 static line
– S2/S1 drain assembly on the static manifold.
(4) Remove any contamination collected in the two drain collector tubes.
(5) Install the pitot−static test adaptor on the P1 pitot−static head and P2 pitot−static head.
NOTE: Refer to the manufacturer’s instructions of the pitot−static test adaptors when you
install the adaptor.

(6) On the P1 pitot−static test adaptor, connect the static hose assembly to the S2 static port.
(7) On the P2 pitot−static test adaptor, connect the static hose assembly to the S1 static port.
(8) Connect the other end of the static hose assembly to the pitot−static pressure output line of
the air test panel.
(9) Connect the dry compressed air source to the air test panel.
(10) Start an airflow at 20 psi (137.90 kPa) into the P1 static port S2 and P2 static port S1.
(11) Connect the purging hose on the openings that follow and make sure that there is an
airflow:
– Static connector for the ADC 2
– S2/S1 drain assembly on the ADC 2 static line
– S2/S1 drain assembly on the static manifold.
(12) Disconnect the purging hose.
(13) Decrease the airflow to the static ports to 0 psi (0 kPa).
(14) Remove the pitot−static test adaptors from the P1 and P2 pitot−static heads.
NOTE: Make sure that there is no fluid or other contamination on the pitot−static head.
(15) Install the drain collector tubes on the static line drains that follow:
– S2/S1 drain assembly on the ADC 2 static line
– S2/S1 drain assembly on the static manifold.
(16) Remove the cap from the static connector on the ADC 2.
(17) Connect the static connector to the ADC 2.
(18) Disconnect the dry compressed air source from the air test panel.
(19) Disconnect the pitot−static test adaptor from the pressure output line of the air test panel.
5. Close Out
A. Remove the tag and close the circuit breakers that follow:

B. Do a leak test of the P2 and copilot S1 systems (TASK 34−11−00−790−805).
NOTE: The static fittings on the drain collector tubes and the ADC are quick−disconnect
fittings. The leak test is necessary only if the regulatory authority of the country of
aircraft registration makes a leak test mandatory.
C. Remove all tools, equipment, and unwanted materials from the work area.
