(AFTER PAINTING OF WING)
8.
With Wing Tip removed, slip Landing Light Lens into position. Trim the Lower
edge to be tight against the row of rivets. The pressure will keep the Lens
pressed against the inside of the spar.
9.
Apply painters tape flush to cut opening in spar. Apply tape, on the Lens, flush
with the outside edge of the raised area.
10.
Apply a small bead of clear silicone seal between the tapes and smoothen with
your finger to form a fillet. Remove masking tape before the silicone hardens.
This will aid in preventing the penetration of water and dirt.
11.
Access Landing Light mounting area through lower inspection opening. Rivet
Landing Light with mounts to back side of wing spar using previously drilled
holes. Note that the mounts have slots which allow the light to be angled as
necessary for proper light beam convergence. After adjusting, tighten bolts.
