5.2.1 Wing Dismantling Procedure
Wing folded on the under surface on a pair of trestles, one at the nose, and the
other at the tips:

Check and mark or trace the rotation setting of the sleeves at the ends of the wing and the tension of
the sail on the adjustable sleeves on each side of the wing.

Reduce to the minimum the tension of sail on the leading edges using the screws 6-45 B126410 at the
ends of the leading edge. (Refer to drawing OP10-20ST .)

Unscrew the 2 nose screws B199010 that secure the sail on the leading edges. (Refer to drawing
OP10-23CA .)

Take off the 4 screws FHC B167210 that secure the sail on the sleeves at the ends of the leading
edges. (Refer to drawing OP10-22VO .)

Unfasten the neoprene central joint of the upper surface by means of the zippers.

Remove the keel pocket by means of the zippers.

Remove the screws CHC 6-25 B062510 that fixes the restraining straps of the sail at the ends of the
two central battens. (Refer to drawing OP10-22VO .)

Remove the fine cord of the CORSET, the straps and the pulley blocks attached to the central battens.

Remove the nose battens. The nose battens are in two parts. Drawing D194554 . The back part is
encased in the front part near the king post and held in place by a pushing spring locking pin.
Disengage this part backwards by pushing the pin and pulling from the trailing edge. The front part
should be slid out of the sail by pulling from the opening of the pocket made at the level of the middle
retaining strap (n°1) of the nose battens.

Remove the luff-line quick links at the trailing edge. (Refer to drawing OP10-26CA .)

Remove all of the pieces of the CORSET, the pulley assembly on the hang bracket and the control
lever on the right A-frame strut.

Dismantle the bolts fixing the uprights on the upper U-brackets, and remove the U-brackets from the
hang bracket.


Remove the bolts fixing the lateral upper and lower cables to the cross bar, and pull cables free of sail.

Dismantle the luff line pulleys.

Dismantle the tensioning rail at the rear of the keel.

Slide the sail from the rear of airframe taking care to keep sail clear of the hang bracket and king post
foot.

Remove the king post foot, the hang bracket body and rings. Insert zip-tie in the king post hole to keep
internal sleeve from moving during maintenance work.

Dismantle the bolts connecting cross bar to leading edge.

Slide the crossbar backward to disengage them from the keel.

Remove the aft section of leading edge.

Remove the crossbar protection at the central junction of the crossbar.

Dismantle all parts remaining on the keel, uprights and control bar.

Dismantle all parts remaining on leading edges.

Dismantle the lateral carbon battens of the exterior luff lines by opening the Velcro strips at the interior
end of their pockets. (Open the 2 zippers sewn along the under surface battens in front of the openings
of the bottom lateral cables in order to slide your hands inside the sail.) (Refer to drawing
