1. Pitot/StaticSystem Test
CAUTION: DO NOT USE ANY PETROLEUM PRODUCTS OR LOOSE SEALING MATERIALS ON OR ABOUT ANY TEST EQUIPMENT, STATIC SYSTEM LINES, OR CONNECTORS. DURING THE FOLLOWING PROCEDURES, TAKE PRECAUTIONSTO PREVENT INGESTION OF FOREIGN MATERIALS INTO THE TEST EQUIPMENT AND AIRCRAFT SYSTEMS.
NOTE: The PA-42-720 is equipped with quick-disconnecting test ports forward of bulkhead at F.S.
17.00which use an alternate static system test unit. The following procedure is provided if the procedure using the quick-disconnect ports is not used. The following procedures are to be accomplished only by qualified personnel per FAR
91.171and 91.172, and in conjunction with FAR 23 and AC 43.13-1A.
Use a Barfield Static Leak Tester (Barfield P/N 2397F) or equivalent to perform the following test. A suitable line adapter must also be attained for connection to the aircraft pitot tubes and static vent ports.
(a)
Inspect all vents, ports, plumbing, and instruments for loose connections and physical damage. Replace the appropriate parts as required.
