3For this wing repair, we need to replace the
leading edge (LE) and
the front portion of the
broken rib.
Here you see the replacement LE
material and the two notches
that will need to be cut to carry
the LE past the open area. A
razor saw does this job quickly
and easily.
4Here the replace
ment LE
material has
been fitted
snugly into
place.
To produce the shape of
the rib replacement part,
trace the undamaged rib
next to the damaged
one. Cut the part to
shape and then place it
against the damaged
one.

5Here you see the rib and leading edge
replacement parts
all glued into place.
Tack glue the parts
into place first, then
lightly flow thin CA
into the cracks and
seams to make sure
everything is secure.
6Before you can replace the top and bottom wing sheeting, you first have to add doubler strips under the edges of the undamaged sheeting so you have something to glue the
new sheeting to. You may also need to glue some doublers to the
side of the ribs to form a strong purchase to support the ends of
the new replacement sheeting.
7Here the new sheet- ing has been glued in place. Before closing
up the bottom of the wing,
re-glue all of the inside
seams to make sure you
have strong bond everywhere.
