A. TCAS Directional Antennas
(1) Scope
This procedure covers the removal and re−application of coating to the TCAS
directional antenna. Localized touch−up is allowable and preferred using airbrush
techniques to ensure minimal paint thickness. The touch−up may be applied either
with the antenna on the aircraft or removed from the aircraft.
(2) Procedure
WARNING: SOLVENTS AND COATINGS ARE COMBUSTIBLE. KEEP AWAY FROM
HEAT AND OPEN FLAME.
(a) Clean
Scrape away all filleting and adhesive material from area to be coated. Remove
surface contamination using isopropyl alcohol or reducer.
(b) Scuff Sand
If the entire antenna is to be recoated, sand to primer with 220 grit sandpaper.
An orbital sander is preferred. For localized touch−up, feather sand areas of
exposed radome material to provide a smooth transition to the painted surface.
(c) Final Sand
If the entire antenna is to be recoated, sand primer and through−holes using 400
grit sandpaper or Scotch−Brite so the primer is removed except in swirls
wherever possible.
(d) Final Clean
Clean the surface to be coated with isopropyl alcohol or reducer.
