Rigging Cables

The main danger with the rigging lies in kinking the cable. This is usually caused by careless rigging and 
de-rigging or by over tightening the bolts that attach the tangs to the airframe. (It should be possible to 
swivel the tangs with light thumb pressure.)  Once a cable has a kink the strands are damaged and 
replacement is the only cure. The side cables are particularly important and should receive a frequent 
detailed inspection. Check for cable damage along the length but the main failure area lies immediately 
adjacent to the swaged fitting. Look carefully for signs of strand fracture at this position. Corrosion shows 
itself as a white powdery deposit. Corrosion cannot be cured and the only answer, again, is replacement.  
Even apparently undamaged rigging wires should be replaced every 200 hours.

Cross tube tensioner

The stitching on the cross tube tensioner is easy to see and should be inspected frequently. The rest of the 
tensioner strop is hidden in the sail and keel pocket so that any damage is more difficult to see. Thus do 
take time to inspect this thoroughly, particularly around the VB. Pulleys and the cross tube centre junction 
leveller.  If any damage to the strop is found (fraying, abrasions, cuts or wear to the stitching) the strop 
should be changed before flying.

Wing fabric maintenance

Any cuts or tears at critical areas such as the trailing edge, sail fixing points or similar high load areas, 
must be repaired at either the Avian factory or an Avian approved workshop. Small damage to panels, 
leading edge covers etc., can be repaired with proprietary self adhesive tape. We define small damage as 
abraded holes no more than 10mm diameter and small cuts no longer than 15mm. Anything larger should 
be inspected by Avian approved personnel.

Stitching Damage

Thread damage never gets better and eventually runs. If you abrade a seam or damage the stitching in any 
way, have the damage repaired before it gets worse. Small, non load-bearing areas can often be repaired in 
situ by the tedious but effective method of hand sewing back through the original stitch holes. Use a needle
and only the correct thread: available from Avian or a good sail maker.

Wing fabric cleaning

It is, without doubt, better to keep the wing clean than to try and clean it. Some dirt never comes off 
completely.  With a new glider avoid getting it dirty in the first place by careful rigging and de-rigging. If 
you decide you do need to wash your wing, then select a dry day and have access to a good hose and clean 
water supply. Never use bleaches, strong soaps or detergents. The soap residue can react with ultra violet 
light and degrade the fabric. 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 
sail. (Usually in the nose or wing tip areas.) Removing stains from stitching is difficult.  Resist the 
temptation of scrubbing with a stiff brush as it might do more harm than good.  Ensure that the wing is 
completely dry before de-rigging and storing.
