Section 3: Aileron Control Horn Installation
Step 3
Remove the aileron from the wing panel. Drill a 5/32"
hole perpendicular to the work surface in the location
marked for the aileron control horn. The top of the aileron
will be resting flat on the work surface. This will angle the
horn slightly forward and align the clevis with the hinge
line when installed. It is highly recommended to use a
drill press to drill this hole.

a felt-tipped pen.
