Drill out all windshield and skylight #30 holes to #28.
IMPORTANT: Drill
only the Windshield and Skylight. Do NOT drill the mating strips to #28.
Run a small bead of Silicone Seal along the holes in the mating strips and
rivet the strips to the windshield and skylight. If Silicone squeezes out, do
NOT
try to clean until it has dried.
HINT: Remove only enough of the
plastic protection layer to allow the Mating Strips to be installed. Be careful
not to scratch the Windshield or Skylight.
22.
Squeeze the #40 rivets at the ends of the Mating Strips to flatten the
extending bottom side. A rivet squeezer or Vise-Grip will work well. This
will allow the rivets to set over the wing root and not chafe on the fabric.
23.
Allow Silicone Seal to dry before moving assembly.

Layout and drill Skylight Trim Strips per
FIGURE 07-25
.
26.
Place Windshield Assembly on top of fuselage ribs. Cleco into position
using previously drilled holes in Carry-thru tabs. Skylight should be
centered on the fuselage. Make sure Ribs are centered on holes in Mating
Strip. Use a marker and draw a line, on the protective plastic, on each side
of the Outer and Center Ribs. Mark aft edge of Skylight at forward side of
Station 3.
27.
Remove Windshield Assembly and remove plastic protective layer
between the marks and aft of Station 3 mark. This will allow the rib
centerlines and mounting tab holes to be seen when drilling. Be careful
not to scratch the Windshield or Skylight.
28.
Position AFT edge of forward Trim Strips 1/8" from forward edge of Mating
Strip. Transfer drill #40 through the windshield making sure to drill on
centerline of ribs. Cleco as you drill.
HINT: Tension the strips to the AFT
as drilling to prevent puckering.
NOTE: The Trim Strips will NOT overlap
the Mating Strips.
29.
Position forward edge of AFT Trim Strips 1/8" from AFT edge of Mating
Strip. Transfer drill #40 through the windshield making sure to drill on
centerline of ribs. Cleco as you drill.
HINT: Tension the strips to the AFT
as drilling to prevent puckering.
NOTE: The Trim Strips will NOT overlap
the Mating Strips.
Add an additional hole 1/4" from the aft of all AFT trim
strips or trim off as done previously.
NOTE: Front edge of forward Outer
Trim Strips will be captured under the Wing Cuffs and will not require a
retaining rivet.
