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

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>

advised 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>
