WINDSHIELD & SKYLIGHT INSTALLATION
Lexan windshields scratch very easy. To get a longer service life from your
windshield and other Lexan surfaces, we recommend a soft terry cloth and a
cleaner made for plastic. We use a product called Brillianize. It is available from
RANS or any large aircraft supply company.
IMPORTANT: The big no-no is
NEVER dust off a windshield unless you have sprayed on some sort of fluid. Dry
dusting will readily cut millions of fine scratches into the glazing, dimming its clear
optics.
NOTE: The wing structures must be complete (may be covered and painted) and
attached to the fuselage prior to final installation of the windshield and skylight.
However, the windshield and windshield hold down strip may be fit-up, before
final assembly, without the wings, skylight, and skylight ribs installed. Boot Cowl
must also be on the fuselage to fit-up the Windshield.
If fuel is spilled on Lexan, wipe clean with a clean cloth immediately to lessen the
chance of crazing damage.
(BEFORE ATTACHMENT OF WINGS)
1.
Collect all the parts shown on the part pages for the windshield. Extra
care should be taken when working with Lexan. Lexan scratches easily
and as much as possible of the protective plastic should be left in place
until the aircraft is ready to be flown. The windshield will require some
minor trimming. Lexan can be easily trimmed with aviation snips or by
scoring and snapping off the piece to be trimmed. A sanding block with
80-grit paper works well for dressing up trimmed Lexan.
2.
Drill the outboard windshield tabs located on the leading edge spar carry-
thru as shown in
FIGURE 07-02
. Drill the center tab #30 as well.
CAUTION
NEVER ALLOW FUEL TO COME IN CONTACT WITH LEXAN.
