12.2. WING
General
Careful attention to the recommended rigging and derigging sequences will protect the wing from the risk of
unnecessary damage. The wing must always be transported inside its bag, and the bag zip should face
downwards to minimize the entry of rainwater. Following transport of the wing through rain, open the bag and
loosen the ties to dry the sail in case any damp has penetrated the bag. During transportation, or when stored on
slings, the wing must be supported by at least two points not more than 2.6 metres apart. Supports should be
softly padded, and any support systems used for transport, such as roof racks, must use attachment straps which
are sufficiently secure to eliminate the possibility of damage from vibration and abrasions. STRAPS SHOULD
NOT BE OVERTIGHTENED.
Wing Fabric Maintenance
If damage should occur, small rips up to 25 mm long and more than 50mm from a seam and 100mm from the
trailing edge may be repaired by the use of self-adhesive insignia patch material each side of the cloth, with a
minimum 25mm overlap. Alternatively sailcloth of the same weight as the part to be repaired may be used, with
3M VHB double sided tape used to attach the patch. The fibres should run in the same directions as the material
being repaired. Gentle heat and pressure will improve the bond. Any larger damage or closer to seams or the
trailing edge requires inspection by a qualified engineer and an approved repair scheme. See SB133 for more
information.
Long term exposure to ultra violet light must be avoided - keep the wing de-rigged in the bag or rigged with
wing covers. The sail should be checked with a Bettsometer (see inspection criteria 12.6)
Stitching Damage
All the seams are firstly joined with a double sided sail adhesive tape and then double zig zag sewn. Thread
damage never ever gets better and eventually runs. Since the wing is held together with stitches, its pretty
obvious what will happen when the stitching fails. If you abrade a seam, then have the damage repaired before it
gets worse.
Small non-loaded areas can often be repaired in-situ by the tedious but effective method of hand sewing back
through the original stitch holes. Never use anything but matching spun PTFE thread which is available from
P&M Aviation Ltd.
Wing Fabric Cleaning
There is no easy answer for cleaning sails; it is certainly best if possible to keep them clean! If all else fails and
you need to wash your wing, then select a dry day and have access to a good hose and clean water supply.
Never use strong soaps or detergents since soap residue can re-act with ultra violet light and degrade your fabric
and threads. We recommend a very mild liquid soap (washing up liquid) and a soft sponge. Gently wash the fully
rigged wing, frequently hosing clean. Copious amounts of clean water will not harm the wing and can be very
beneficial in removing sand and grit which may get trapped inside the leading edge pocket usually in the nose or
wing tip areas. Ensure the wing is completely dry before de-rigging/storing in the bag.
Check your sail for ultra violet damage
regularly. Flying with a damaged sail could
cause structural failure, injury or death.
CAUTION
NEVER STORE THE WING IN A SEALED WING
BAG WHEN WET - leave the zip open to allow the
moisture to evaporate.
Never use spirits, alcohol, thinners or any strong
detergents when cleaning the sail. These may
damage the cloth or threads, leading to
structural failure of the sail fabric which could
result in injury or death.
