ALL Kitfox™ Owners
Flaperon Hinge Bearings MANDATORY
SkyStar Aircraft Corporation
Kitfox™ owners have reported that some hinge bearings on the
flaperon torque tube have slid to one side and out of the hinge
bushing. Because of the potential problems that this could create,
your safety makes compliance with this Service Bulletin
Make sure the bearing is centered into the hinge bushing. Model
1,11 & III owners use Fig.- 1. Drill and rivet two 3/32”x1/8”
through the top skin and into the flaperon toque tube 1/4” out board
of each hinge opening. Model IV, Model IV-1200 & Speedster owners,
determine which side of the hinge that the bearing flange is on (Fig.
2). Drill a hole approx 1/4” out board of the hinge flange in the bottom
skin, large enough for a 3/32” rivet, head and all (the end of the
hinge bearing extends approximately 1/2” to each side of the
flaperon hing). Then drill a 3/32”
hole into the
flaperon torque tube approximately 3/16” outboard of the bearing.
Using a short piece of 1/8” or less I.D. tubing as a spacer on the
rivet pull shaft (view A-A), rivet a 3/32”xl/8” Alum. rivet into
the flaperon torque tube. Creating these “stops” will hold the
bearings in place, and open an extra drain hole for the hinge area.
