snap a bit hard you can bend your wing tube or, in the worst case scenario

a good break for the snap.</SPAN></FONT><o:p></o:p></P></DIV>

style="FONT-FAMILY: Arial; FONT-SIZE: 10pt">So strapping on my asbestos
underwear I decided to do some testing of my own. At the end of
November 2004 it was nice here in NJ. I took the Focus-2 and the
Temptation out for a day of Masters 2005. Both planes were inspected for
tube tightness and the wing covering touched up with the
glove-iron.</SPAN></FONT><o:p></o:p></P></DIV>

style="FONT-FAMILY: Arial; FONT-SIZE: 10pt">Back in the shop the first thing
that I noticed was new wrinkles in the covering on the Temptation
wings. Nothing was loose. To test this I put the wing-tube in the wing and
leaned on it a little. All was well but I was beginning to think that the
wing must have flexed to cause the covering to loosen up. A bit like
what the covering sometimes does around the aileron horns. It this case it
was at the roots above the tubes - both
sides.</SPAN></FONT><o:p></o:p></P></DIV>

<P class=MsoNormal style="MARGIN-LEFT: 0.5in"><FONT face=Arial size=2><SPAN
style="FONT-FAMILY: Arial; FONT-SIZE: 10pt">Then I turned to the Focus-2
wings. Not good! The wing-tube could now be moved up and down and I could
hear foamy crunches in both of the wings. Both wings have Carbon tube wing
tubes and it dawned on me that they could not bend (much) or stay bent. That
is why I had not seen this before. The forces were applying themselves
to the ends of the wing tubes. I opened up both panels and added epoxy and
micro balloons to stabilize the sub ribs. It was an easy repair but could
have been a lot worse if I was not looking for
it.</SPAN></FONT><o:p></o:p></P></DIV>

damage is cumulative and that it does not show up initially. It
certainly had not revealed itself while I had been demonstrating the
2005 schedule over the late summer of 2004. So where does this leave
me? I think we have a potential problem that requires frequent
preventative equipment inspection depending upon the planes that you fly. If
you can slow down your plane and it is at around 10 lb you may never see
this happening.</SPAN></FONT><o:p></o:p></P></DIV>
