the bends are all in the same plane. (7075 is a hard aluminium alloy and extra care must be taken while
profiling to avoid broken battens.) To reduce the curve, do the opposite of the above either over your knee
or preferably by pressing on a flat surface. If you have a point bend try and remove it.
MAINTENANCE
Annual strip down and factory inspection
Avian recommend that the Java Comp has a factory inspection every year or 100 flying hours which ever
is the sooner. This is a sensible precaution to take and is offered by Avian at special prices in the months
of January and February. An additional benefit of the strip down is that the latest upgrades can be fitted,
often for free.
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.
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.
Carbon Spars
Carbon fibre spars must be looked after carefully. Damage to them is likely to be much less obvious than
to a metal tube. Any visible damage could signify serious structural damage and should be inspected by
Avian before flight.
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.
