OPTIONAL LANDING LIGHTS INSTALLATION
•
Optional landing lights may be installed during or after Wing Assembly is
complete.
•
RANS uses a 10 amp breaker and 18 gauge 3-conductor shielded wire and a
separate wire for grounding.
1.
Refer to
SECTION 006H
and collect all the parts shown on the part pages for the
Landing Lights. Extra care should be taken when working with the Lexan Light
Lens as they may scratch easily.
2.
Cut an opening in each Forward Wing Spar per
FIGURE 06-01A
. Polish all cut
edges with fine sand paper. Also polish the tip end of each spar to help prevent
scratching the Landing Light Lens when fitting up. Refer to
FIGURE 06-01B
for
final cutout dimensions.
3.
Cut Landing Light Lens about 1/8” outside of the formed trim lines. This will allow
final trimming during fit up.
4.
Slip Lens into Spar. Center raised area within cut-out in spar. The top edge will
rest against the spar radius.
5.
The lower edge will need to be trimmed after riveting the Bottom Wing Skin in
place. The lower edge will set against the rivets and will allow the Lens to snap
into place. Remove Lens from spar.
6.
Assemble Landing Light to Landing Light Mounts.
7.
Position assembly in spar, centered on opening. Refer to
FIGURE 06-01C
. Tape
in place and view from the front. Adjust as needed. Transfer drill #30 through
Mount holes. Remove and proceed with assembly of wing.
NOTE:
Remember to route Landing Light wires during Wing assembly. Route
wires in wing and out to the Landing Light through the grommets in the
wing ribs. Leave extra length to reach through the fuselage. If wings are
assembled the wire may be ran inside the leading edge spar, then routed
to the aft closer to the root. Be sure wire does not interfere with any
controls.
