snap a bit hard you can bend your wing tube or, in the worst case scenario
break, your wing. The plane is pulling some G's at the bottom of the
loop and then you add more by putting in a lot of elevator to get a
good break for the snap.</SPAN></FONT><o:p></o:p></P></DIV>

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">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>

<P class=MsoNormal style="MARGIN-LEFT: 0.5in"><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">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>

<DIV>
<P class=MsoNormal style="MARGIN-LEFT: 0.5in"><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">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>
