WING INSTALLATION
Please read the entire section before you continue with Wing Installation.
We recommend having all assemblies and installations related to the Wing
completed before the Wings are final installed to the airplane. It is
NOT
necessary to trial-fit the Wings to the Fuselage at an earlier assembly stage.
The following items should be completed at this stage:
•
Wings are painted
•
Ailerons, Flaps and Gap Seals installed
•
Aileron and Flap Cable Exit Fairings trimmed and fit to Wing
•
Wing Tips painted and installed
•
Wing Root Rib Closeouts (root covers) painted and installed
•
Fuel Sight Gauges installed to Wing root
•
Lift struts assembled
All of the above items are easier to do with the Wing on sawhorses than on the
airplane.
It is recommended to hang both Wings at the same time (one at a time). You will
need at least one helper. However, it is more comfortable to have two helpers.
Refer to
parts page 005-01
.
1.
Drill out the 1” U-Brackets (stainless steel) to fit a 5/16” Bolt. Drill the
attach hole for the Fuselage only.
2.
Bolt the 1” U-Brackets at the Left and Right side of the Fuselage to the
bushings at Station 3. Use hardware as shown in the parts manual.
3.
Install the Hinge Cubes as shown in the parts manual to the Trailing Edge
Spar Root Fittings.
NOTE: The slotted portion will bolt to the 1” U-bracket
on the fuselage.
4.
Rest the wing on 2 saw horses beside the fuselage.
5.
Previously the Lift Strut Fittings should have been checked for fit on the
corresponding Strut Attach Plates on the Wing. If not, use a fine file or
sandpaper to remove as little material as possible.
IMPORTANT: Remove
material only from the fittings, NOT from the Strut Attach Plates.
6.
IMPORTANT: The FWD attachment hole in the Leading Edge Spar and
Spar Patch should have been drilled to 3/8” during Leading Edge Spar
assembly. If not, refer back to WING SPAR ASSEMBLY and do so now.
7.
Modify the FWD end of the Carry-Thru Bushing (“T”- Bone) per
FIGURE
