S-7S WING – MAIN STRUCTURE ASSEMBLY
NOTE: 3M Brand DP-460 Epoxy Adhesive is recommended for bonding the
sheet metal wraps to the FWD & AFT wing spars. Leading Edge, Root, and Tip
Wraps are riveted with 1/8” Stainless Steel Flush rivets. A suitable 1/8” Dimpling
Tool and Counter Sink will be required. Aircraft Spruce has an inexpensive 1/8”
Pop Grip Dimpler.
IMPORTANT: Wings are mirror assemblies, repeat the procedures described for
one to both, unless otherwise specified.
It is NOT necessary to trial fit the wings to the fuselage after building the wing
frames. We recommend having all assemblies and installations related to the
wing completed, before the wings are final installed to the fuselage.
WING SPAR ASSEMBLY
1. Prior to the assembly of the Spars, it is important to familiarize yourself
with the orientation of the Spars. When working with long tubing such as
Leading and Trailing Edge Spars, padded sawhorses provide an ideal
workbench.
2. Locate the root and tip end of both the Leading and Trailing Spars, refer to
FIGURE 05-02 and 05-02A . You must also determine the forward and aft
side to each spar span wise.
3. IMPORTANT: Double check that you have the spars correctly orientated
to a
ssemble a right and left hand of each spar. Mark all four spars with
“left, right, forward, and aft”. NOTE: The left hand Leading Edge Spar is
also identified by the pitot/static mounting hole. Refer to FIGURE 05-02 for
location. Be sure to build a left and right hand set of spars. Be sure the Lift
Strut Attach Plates are orientated correctly on each spar. Refer to
FIGURE 05-03 .
4. Locate the root end of both Leading Edge Spars and the 2 slotted Leading
Edge Spar Root Doublers.
5. Squeeze the slotted Root Doubler together and slide it in the root end of
each Leading Edge Spars, with the slot facing down. Push the doubler in
with a block of wood until flush with the Spar root end. Refer to
FIGURE
05-05 . HINT: A large hose clamp may be used to squeeze the Root
Doubler together to allow easier insertion.
6. Transfer drill the root doubler # 30 using the pre-drilled holes in the spar
as a guide and cleco to the spar as shown in
FIGURE 05-05 .
