16. Walking along the length of the leading edges feel with your fingers to check that
they are free from dents. Check that there is a similar leading edge curvature when
looking down the inside of the wing from the nose to each wing tip.
17. Check through the sail inspection zip to ensure that the wing wire and cross tube
leading edge bolts are secure.
18. Check that the keel is straight and then check that the tensioning strap is secure,
correctly fitted and that the split ring is in place. As shown in the previous diagram.
19. Check that the cross-tube ends are meeting correctly (the ball should be engaged
in both fittings). Also check that the cross-tubes are straight and dent free.
20. Check that the wires are undamaged. Look out for corrosion and fraying. Pay
particular attention to inspection of the wing wires as, in normal flight, these are the
most heavily loaded.
INSPECT BOTH ENDS: THE BASE BAR END AND THE
CROSS TUBE JUNCTION END.
REMEMBER: IF IN DOUBT DO NOT FLY!! RETURN YOUR GLIDER TO
AVIAN LTD FOR A THOROUGH STRIP-DOWN.
21. Check operation of the VB. Pull the VB. rope and check that it pulls on smoothly
and releases. If it is jammed check and release if caught.
NOTE:
If instruments are
attached to the right hand upright it may interfere with the VB. operation. The VB.
cord runs down the rubber back of the right hand upright. Crushing the rubber back
impedes the movement of the cord. It may then be possible to pull the VB. but not to
release it. This is easily cured by inserting a length (30cm) of batten material inside
the rubber back of the upright. (This stops the rubber back from being crushed.)
22. Finally check that all the quick release fasteners are secure. Pay particular
attention to the base bar quick pins.
NOTE
: As the glider is moved and placed on
the ground the safety rings in the base bar quick pins may contact the ground. Long
grass seems most likely to cause the problem but it is possible to remove the safety
ring from the pin. The problem is minimised if you put the pins in from the back of
the base bar. (Thus when the glider is sitting on its keel the head of the pin will
contact the ground rather than the safety ring.) Special attention should be given to
checking quick release fasteners.
