Owner`s Manual
General
Careful attention to the rigging and de-rigging sequences will reduce the risk of
accidental damage. Repairs should be undertaken by the Avian factory or an
approved dealer using genuine Avian spares.
The correct storage of your glider will also greatly influence its life.
The glider should always be stored
WELL PACKED
COMPLETELY DRY
WELL SUPPORTED
IN A DARK, COOL AND DRY PLACE.
N.B. Regular coastal flying will cause increased corrosion of spars and fastenings.
More frequent regular inspection is therefore recommended in this case.
Airframe Maintenance
Apart from damage caused by over stressing the glider i.e. crashing etc. the major
wear and tear on the glider happens in transit.
Aluminium Tubing
Care and consideration in de-rigging and transportation will pay dividends in airframe
life. Damage to any one of the structural members is serious and the only remedy is
replacement. Insufficient care during ground handling or transportation can lead to
tube abrasion or indentation. The former accelerates fatigue fracture and the latter
reduces the strength of a component. Keep a regular watch for tell-tale hair-line
cracks, which are most likely to occur in high stress areas such as around bolt holes.
If you bend, dent or damage the tubular members in any way, seek immediate
professional advice before flying again and have replacement parts fitted.
Fasteners
Any fastener (i.e. nuts bolts etc.) which is bent or shows signs of wear or corrosion
should be replaced immediately. Nyloc nuts should only be used ONCE. One clear
thread of the bolt should stick out beyond the end of the nyloc. Nuts should be
tightened only so that they are snug. In most applications on a hang glider the nut is
only there to stop the bolt from falling out. DO NOT OVER-TIGHTEN NUTS AND
BOLTS. Over-tightening them can crush the tubes and damage the hang glider.
