Use the third Mating Strip to fabricate an aft capture strip to attach the
Skylight to the Station 3 fuselage tabs shown in
FIGURE 07-32
. Center
the mating strip on the fuselage and the Station 3 tabs. The capture strip
should slightly overlap beyond the aft edge of the skylight. Transfer drill
#30 through tabs and cleco in place.
HINT: It is easier to locate the holes
by placing the capture strip between the Skylight and fuselage, then
transfer drill from the top.
Cleco Strip to top of Skylight.
33.
Flap Fillet from Wing Assembly will mount to side of fuselage during final
assembly and will retain the outer aft edges of the Skylight. Refer to
FIGURE 07-33
. Hold Flap Fillet against fuselage side. Mark and trim aft
Capture Strip where it overlaps the Flap Fillet. If desired, locate a #40 hole
on each end of Capture Strip similar to Mating Strips.

Install Rubber Trim along the outer edges of the skylight. Open the Trim
and apply a small amount of cyanoacrylate glue (Permabond, Superglue,
etc.) in the crease to retain the Trim in place. Do not glue the forward or
aft ends until the wing cuffs and Flap Fillets are installed.

Only a drop of glue ever couple inches is needed. Do NOT allow glue to
squeeze out beyond the Trim.

HINT: Apply
masking tape flush with the edge of the metal strips. Place tape about 1/8”
from the metal strips on the Lexan.
Clean Lexan and apply Silicone Seal.
Form into a fillet with your finger. Refer back to
FIGURE 07-32

HINT:
Spray finger with Formula 409
