(12) Remove sleeving from repair kit and position on radome until edge of tab is overlapped 1/4--inch to 1/2--inch on
radome and at least 1/4--inch on sensor housing (see Figure 5).
(13) Thermally protect newly replaced radome and adjacent radomes from heat (using scraps from old radome, etc.).
CAUTION
Exercise caution when using heat gun on active portion of radome. Heat deformation can
occur.
(14) Apply heat to sleeving with heat gun, turning frequently to prevent uneven heat.
WARNING
Be careful when repositioning sleeving. Heated sleeving can become extremely hot and
burn hand or fingers.
(15) If sleeving becomes displaced during initial stage of process, carefully reposition sleeving with fingers, needle nose
pliers or wooden end of cotton swab. Continue heating process until sleeving becomes snug around complete perimeter
of radome.
NOTE
It is critical to verify that heating was properly applied to sleeving. There must be visible evi-
dence of squeeze out along the entire perimeter of the sleeving ends. This shows that the
sleeving was correctly heated. If adhesive squeezes out, but wetting of the radome and
housing is not seen, thermal protection for affected radomes must be reinstalled. Sleeving
must be reheated while applying pressure on sleeving until squeeze out is acceptable.
(16) If cured adhesive is found on active radome surface, carefully remove it with orange stick or equivalent. If adhesive
cannot be removed, repeat radome installation with new radome.
(17) Remove all thermal protection used during shrink sleeving installation.
