A. Installation of the TCAS Antenna
(Ref. Fig. 401/TASK 34-43-11-991-001)
WARNING : OBEY THE COLOR CODES WHEN YOU CONNECT THE ELECTRICAL CONNECTORS
_______ (THIS WILL PREVENT CROSS-CONNECTIONS). MAKE SURE THAT YOU INSTALL THE ANTENNA IN THE CORRECT DIRECTION. IF THE ANTENNA DOES NOT POINT IN THE CORRECT DIRECTION, THE TCAS WILL ONLY SENSE TRAFFIC BEHIND THE AIRCRAFT.
(1)
Remove the used sealant from the fuselage structure (2) with a nonmetallic scraper.
(2)
Clean the component interface and/or the adjacent area with CLEANING AGENTS (Material No. 11-004) and a lint-free cloth.
NOTE : If you install the same antenna it is necessary to clean it
____ with CLEANING AGENTS (Material No. 11-003).
(3)
Do an inspection of the component interface and/or the adjacent area.
(4)
Put the new O-ring (4) in the correct position on the antenna (6).
(5)
FOR 7SG1
Install the foam washer (5).
(6)

____
(10)
Safety the coaxial connectors (1) and (9) with corrosion-resistant steel lockwire 0.4 mm (0.016 in.) dia..
(11)
Install the antenna (6) on the fuselage structure (2) with the screws
(7) and the washers (8) and then tighten:
-TORQUE the screws to between 0.27 and 0.37 m.daN (23.89 and 32.74 lbf.in)
(12)
Make sure that the bonding contact resistance between the antenna (6) and the fuselage structure (2) is not higher than 5 milliohms (Ref. TASK 20-28-00-912-005).
(13)
Install the MISCELLANEOUS (Material No. 19-002) (10) on the screw heads with the SEALANTS (Material No. 09-016) . This is necessary for the subsequent removal of the antenna. (see detail on section B-B).
(14)
Put a bead of SEALANTS (Material No. 09-016) around the antenna (6).
(15)
Let the sealant become dry.
(16)
Apply STRUCTURE PAINTS (Material No. 16-003) to the sealant around the antenna and the screw heads.
