AIRFRAME
The airplane is an all metal, four-place, high wing, single
enginel
airplane equipped with tricycle landing gear and is designed for
general utility and training purposes.
The construction
of
the
fuselage
is a conventional
formed sheet
metal
bulkhead, stringer, and skin design
referred
to
as
rsemimonocoque.
Major
items of structure
are
the front and rear
carry through spars
to
which the wings
are attached, a bulkhead
and forgings
for
main landing gear attachment
at
the base of the
rear door

to
the forward door
posts
and extend forward

The externally braced wings, containing integral fuel tanks,
are
constructed of a front and
rear
spar with formed sheet
metal
ribs,
doublers, and stringers. The entire
structure
is
covered
with
aluminum skin. The
front
spars
are
equipped with
wing-to-fuselage
and wing-to-strut attach fittings.
The
aft
spars
are equipped with
wing-to-fuselage attach fittings,
and
are partial span spars.
Conventional hinged ailerons and single slot
type
flaps are attached
to
the trailing edge
of
the wings. The ailerons are constructed of a
forward spar containing balance weights,
formed sheet metal ribs
and "V"
type corrugated
aluminum skin joined
together at the
trailing edge. The flaps are constructed basically the same as the
ailerons, with the exception of
the
balance weights and the addition
of a formed sheet metal
leading
edge
section.
