Re: Wing Load Testing -- Wing damage

Kevin Boddicker

Follow the repair plans in the plans manual. I think it states to
sand back each ply and expose at least one inch of each ply. So the
sanding needs to be a sort of scarf. Then
re-apply the glass cloth in it's original place per the lay-up
schedule. Then apply one bid over the whole repair. I think it is in
chapter three of the plans.
My opinion is that to test without the repairs would be a waste of
time. It would be interesting, but not much value to the question at

I am still looking for ideas on repair of the wing prior to testing,
esp. the leading edge where it attached to the seatback bulkhead.

I would also like to hear any ideas for how to jig the wing prior to
testing since the wing is no longer attached to the fuselage.

I picked up the wing this weekend from Sam Kittle and brought it
The wing was cut out of the fuselage with a sawzall and their is
in two areas. (The fuselage is going to be used in a motor
glider.) I
am asking for opinions on repairs.

The front edge of the wing attaches to the rear of the seatback
bulkhead. In this area the wing was separated with a rather wavy cut
about 1 inch from the bulkhead. This cut exposes the foam core
but does
not enter the spar caps.

The rear edge of the wing has 2 cuts parallel to the fuselage
wall and
about 1 inch in. The longest of these is about 3.5 inches in length.

In all cases the damage appears to involve the 45 deg Uni but not
spar caps.

Two questions: Do we need to repair these areas before testing? What
repair would you do on the leading edge?

Thanks for any help --
