Preflight Procedure
Along the left leading edge
Carefully check the entire length of the leading edge pocket to insure that the mylar insert is lying flat
in the pocket. If any section of the mylar is folded under, de-tension the crossbar, remove the batten
closest to the area of distortion, and unfold the mylar.
Failure to correct folded under or severely creased mylar will cause a severe alteration
of the flight characteristics of the glider which may lead to a dangerous loss of control.
While pushing up on the leading edge between the nose and the crossbar junction, step on the bottom
side wire with about 50 lbs. of force. This is a rough field test of the structural security of the side wire
loop, the control bar and the crossbar, and may reveal a major structural defect that could cause an in-
flight failure in normal operation.
Open the crossbar junction access zipper and look inside, making sure that the bottom side wires are
properly secured to the crossbar and that the nut and safety ring are in place. Check the attachment of
the cam lever plate to the crossbar and leading edge, the attachment of the support strap, and VG
activation cable. The neoprene protector can be slid back to check the cable attachment. Re-close the
zipper.
At the left wingtip
You have already preflighted those parts of the glider accessible only with the tip fairing removed. At
this time, check the tip again for secure and proper installation.
Along the trailing edge, left wing
Check that there are no tears in the sail material along the trailing edge.
