Gap seals ailerons LS8
-a, LS8-b, LS8-18:
(1) Place wing vertically on padded supports with leading edge downward
and secure at spar tongue or fork against falling down.
(2) Cut Teflon tape to ample aileron length and cover one edge with 4965
adhesive strip (9mm wide) without pretension to avoid warping.
(3) Clean bonding region on wing after aileron disassembly from adhesive
residues and paint with primer (Pattex).
(4) After approximately half an hour of drying, place inner Teflon seals
tapes to wing such, that about 2 mm (0.08 in) of the wing trailing edge
are not covered. Remove masking from seals tape during bonding
process.
(5) Place aileron into bearings provisionally, deflect fully and mark rear
wing edge position on aileron using a pencil for both deflections.
(6) Bond adhesive strip to aileron such that its leading edge is at least 5 mm
(0.197 in) in front of marking. Also at bearing cut-outs a minimum of 5
mm (0.197 in) must remain.
(7) Install aileron completely, see section 4.1. Remove masking tape from
aileron bonding strip and press Teflon tape on without undue pulling or
warp. Cut surplus Teflon tape along wing rear edge marking (or edge
5mm behind bearing cut-out), but avoid cutting into gelcoat.
