C. Preparation for Installation
   (1) Precautions :
NOTE: If you install the same antenna it is necessary to clean it with Non Aqueous Cleaner-General - - (Material No.08BAA9) .
   (2) Remove the used sealant from the bulkhead with Non Aqueous Cleaner-General - - (Material No.08BAA9) and a Textile-Lint free Cotton - (Material No.14SBA1) .
   (3) Clean the component interfaces and the adjacent area.
   (4) Do an inspection of the component interfaces and the adjacent area.
4. Procedure
CAUTION: MAKE SURE THAT YOU DO NOT DAMAGE THE FUSELAGE WHEN YOU REMOVE THE SCUFF PLATES.
Subtask 34-36-11-420-050-A
A. Installation of the Localizer Antenna
   (1) On the bulkhead (2), apply Release Agent-- Liquid Wax - (Material No.14DBB1) with SCRAPER - NON METALLIC to the attachment of the localizer antenna and to the support of the localizer antenna (1).
   (2) On the bulkhead (2), apply Polysulfide Sealant-Low Adhesion Fillet Structure (Material No.06AEB2) with a nonmetallic scraper to the attachment of the localizer antenna and to the support of the localizer antenna (1) (Ref. AMM TASK 51-76-11-300-001).
NOTE: Make sure that the screw holes do not show any signs of sealing compound.
   (3) Remove the blanking caps from the coaxial connectors (3) and (6).
   (4) Make sure that the coaxial connectors (3) and (6) are in the correct condition.
   (5) Put the AIPC 34-36-11-01-010 O-RING (4) in the correct position on the antenna (1).
   (6) Connect the coaxial connectors (3) and (6) to the localizer antenna (1).
   (7) Attach the localizer antenna (1) with the screws (5).
   (8) Remove the unwanted sealing compound from the support of the localizer antenna (1) with a nonmetallic scraper.
   (9) Make sure that the bonding contact resistance between the antenna (1) and the fuselage structure (2) is not higher than 5 milliohms (Ref. AMM TASK 20-28-00-720-005) .
   (10) Make a seal around the support of the localizer antenna with Polysulfide Sealant-General Purpose Fillet - (Material No.06AAB1) or Polysulfide Sealant-Fuel Tank Quick Curing - (Material No.06ABF1) (Ref. AMM TASK 51-76-11-300-001).
