Shops may want to consider making this a separate
work-order item with its own sign-off.
Complex aircraft often (and RVSM capable
aircraft always) have dual pitot-static systems,
which should be independent… however, if an
aftermarket air-data computer was inadvertently
connected to pilot’s pitot and co-pilot’s static
systems, it could be damaged if only one side was
run up. It’s best to test both sides together, unless
the maintenance instructions specify otherwise.

information, with copies of the relevant FARs,
ACs, ADs, tabs for each aircraft they test, copies

Proceed cautiously. If you begin introducing
vacuum and do not see the immediate results you
expect, stop and recheck your setup.
Keep a little bit of airspeed showing on the airspeed
indicator while running a pitot-static system up.
This assures the airspeed is not back-pressured.
See the FARs for system leak requirements –
leaks considered minor on unpressurized aircraft
can cause major errors on pressurized aircraft.
The job is not complete until the paperwork is
done. q
