An approved external air supply can be con-
nected to an adapter (Figure 9-6) located in a
covered access on the left side of the rear fuse-
lage. A flapper-type check valve in the adapter,
unseated when a connection is made, permits
flow in one direction only.
Figure 9-7 illustrates that the pneumatic sys-
tem is being supplied from an external air-
source. Basically, the external supply directs
airflow to the left side of the 10th pneumatic
manifold. During engine starting, the engine
bleed-air shutoff valves and the isolation valve
will open as previously described to direct
the airflow to the affected air turbine starter.
The external supply can also be used for air
conditioning and pressurization systems. In
this case, the isolation switch, bleed-air
switches, and system switches must be se-
lected as required.
