
Nylon stop washers (D274080-M) are positioned under the Nylstop of the assembly screws
of the leading edge to serve as a rest for each of the central battens.

Note that the rear keel bolt, screw FHC 6-85-15 (B168710) is longer than the front one,
screw FHC 6-80-12 (B168310), with two 6x14 stainless steel washers (B810610) on top of
the upper nose plate to hold the upper rigging cable later. Do not tighten this nut yet.

Apply threadlock and tighten the other bolts gently, being careful not to crush any of the tubes
by over-tightening the bolts! The leading edges must be free to pivot when rigging and
unrigging, so only tighten the bolts until there is no more free play, and make sure to tighten
them evenly. This can be checked by making sure the plates remain parallel.
Do not assemble the goose neck and lower front cables at this point.
5. Fitting Crossbar to Keel

Refer to drawings U028271-M040 & OP10-09TR .

Holding the crossbar above the end of the keel, slide the protection sleeve over and up the
keel to within about a foot of the nose plate.

Place a spacer (e.g. a broom handle or the kingpost) between the crossbar and the keel, Figure
5-7.

Apply threadlock and tighten the nuts holding the lugs of the restraining straps to the crossbar,
leaving enough slack to allow forceful rotation of the plates. Some thread (just a little) should
show from the nut. It may help to tighten the nuts quite firmly, and then back-off a little to
allow the required movement.

Pull the back-up pull back bridle firmly down the sides of the crossbar and carefully secure
them with a
self-tapping screw (B199010) into the hole in the crossbar, placing a
countersunk washer M6 (B830610) between the screw and the back-up pull back bridle,
Figure 5-8.

Remove the spacer.

6. Leading-Edge Fittings

The hole in the leading edge is 8mm on the outside and 10mm on the inside (as mentioned
earlier) to receive the
spacer (D252360) .

Apply Teflon® lubricant spray on the flat side of the aluminum cup washer (D264550) and
its mating part.

Assemble the parts as per the drawing OP10-07CA .

The nut should be threadlocked and tightened to remove all free-play, but still allow smooth
rotation of the leading edge cardan.
7. Leading-Edge to Crossbar Junctions

Refer to drawing OP10-11BT .

Slide the aluminum fittings crossbar V (D264520), into the ends of the crossbar and check
the fit of the bolts screw CHC 8-50-15 (B085110) and screw BHC 8-96/11 (B090960) .
