Rather than take the wings off just a slot in the
fuselage above
and below the spar caps would be required to get
the new spar caps in.
I think. What do you think Alex?

Paul Lamar

I should have some more early construction pictures.
Will check when home this PM.

These wings have a full-length main 'I-beam' spar
that is built up (glass-foam-glass), then laminated
to the inner skin of the lower half of each wing
(the skins are also a glass-foam-glass sandwich).
The carbon fiber portion of the spar cap structures
are actually part of the wing skins as supplied in
the kit.

The upper portion of the spar I-beam is bonded to
the inner skin of the upper wing half during wing
closeout.  This bond creates the complete upper spar
cap from the two components: CF in the wing skin and
the top of the I-beam.  Closeout is a complicated
and time-sensitive process that must be done exactly
right to assure complete upper spar cap-skin bonding
over the 27' wing.  Without adequate bonding, the
wings are likely to fail in compression of the upper
skin.  I can't quite tell from these pictures if
there was a spar cap bonding issue with this plane's
wing.

After assuring adequate bonding of the spar cap
during closeout, the leading edge and rear shear web
are glassed in.

The outer wing skins are actually quite thin and
fragile, although numerous laminations above, below,
and around the wings are used to secure the wings to
the fuselage using only the outer skin.

The strength of the wing depends on its entire
structure.  Therefore, I think it would be virtually
impossible to try and rebuild the spar systems of
this plane.

The expert in this area is Tom Scott, the current
owner of Quikkit, which makes the Glass Goose.
