While pushing up on the leading edge between the nose
and the crossbar junction, step on the bottom side wire
with about 75 lbs. of force. This is a rough field test of the
structural security of the side wire loop, the control bar,
the kingpost, and the crossbar, and may reveal a major
structural defect that could cause an inflight failure in
normal operation.
Open the crossbar junction access zipper and look inside,
making sure that the safety ring on the junction bolt is in
place and that the wires are secure and properly routed.
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.
