Composites
The wing tip fins are made of composite carbon materials and secured to the sail by
means of quarter-turn screws.
When you check the tip fins, make sure that they are not cracked, dented, or
delaminated, which might detach them from the sail. Also check the condition &
working order of the quarter-turn screws.
The two fins provide stability in roll and yaw at high speed. Their structural integrity is
important. Each tip fin should be checked every 50 hours and after a long period of
storage in a hangar, or after transport, to find any possible damage and to insure that the
fastenings are working and that the materials are in good condition. The protective sticker

, which limits friction on the ground may be replaced in case of scratches or
loss of adhesive.

Sail
Apart from the consequences of heavy landing, or of exceeding flight limitations, the
major factors requiring attention are fatigue, wear, UV exposure and heat.
Inspection
Check for tears in the sailcloth or any loose or unraveled seams.
Check that none of the securing points (straps, eyelets) secured to the structure (nose, central
battens, wing tips) are damaged or worn.
Check the normal operation & complete closure of all zippers & of the assembly of the central
neoprene joint.
Check the condition of Velcro fasteners on the removable keel pocket.
Check the condition & elasticity of the central neoprene joint of the upper surface. It should retain
lateral tension and not suffer ripples once the CORSET is stretched to the maximum
(configuration for high speed). If not, its replacement is imperative.
Fabric samples are stitched in the middle of the sail near the trailing edge, on each side of
the central neoprene joint. Each strip is made of two pieces of sailcloth sewed together.

During each overhaul, a strip must be cut off along the lateral stitching and on one of the
transversal lines, and sent to the Air Creation factory to be submitted to a test of wear and
