(AFTER COVERING AND PAINTING OF WINGS / AFTER INSTALLATION OF
AILERONS AND FLAPS)
1.
When fitting the Wing Tip, work carefully not to scratch the paint on the
Wing. Trim Wing Tip at the base of the flared material. The Wing Tip will
need some additional trimming and sanding, before the surface finish can
be applied.
2.
Use a hot iron to burn a small hole through the fabric at each hole along
the Tip Rib.
3.
Slide the Wing Tip all the way onto the Wing.
4.
It will be necessary to trim the Wing Tip to within 5/16” of the centerline of
the Tip Rib. Trim the Wing Tip to allow for sufficient clearance to the
aileron. Refer to
FIGURE 05F-04
. Tape the Wing Tip in place to avoid
movement.
5.
Use a hole-finder to mark and drill #40 holes in the Wing Tip to match the
pre-drilled holes in the Tip Rib. Cleco as you drill making sure the Wing
Tip fits tightly.
6.
Slide the AFT Closure (small metal rib) inside the AFT end of the Wing Tip
and clamp in place. Mark 3 holes top and bottom on the Wing Tip
approximate centered on the Rib Flange and drill # 30. Rivet the Aft
Closure in place.
NOTE: Use the metal rib to align the tip’s aft end with the
aileron neutral setting.
Refer to
RIGGING
section.
