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

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

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>

that stress 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>
