BUILDING THE WING
Periodically we took photos of the various components and assemblies that would be hidden from view after covering. We wanted to be able to show the FAA inspector the fine workmanship.
The
first step in the construction of the wings was the preparation of the
forward and aft spars. An aluminum web insert was positioned inside each
tube spar and carefully riveted in place. Two strut attachment fittings
were also rivetted in place on each spar.
Aluminum tube
cross-bracing was installed between the two spars. The primary wing ribs
and false ribs were glued in place with epoxy structural cement. (Gooey
and messy, but VERY strong.) Latex gloves kept MOST of the glue off of
the students' hands and clothes
