LETTER #47 DATE:
August 22, 1995 SUBJECT:
Rudder Pedal Torque Tube Cracking APPLICABILITY:
Kitfox™ Models 1 through 4, Classic 4 COMPLIANCE:
As required FROM:
SkyStar Aircraft Engineering Department We
have recently noticed that some of the rudder pedal torque tubes in
our older factory aircraft have started showing signs of fatigue at
the positions shown in Figure 1. Because of this we recommend that
each owner/builder inspect his torque tubes carefully for any signs of
fatigue or cracking prior to the next flight of the aircraft. You
should remove the assembly from the aircraft so it may be inspected
under more optimal conditions. Prior to inspecting the areas
indicated, remove any paint or powder coating around the welded joints
with a piece of emery paper. If no cracks are seen, repaint the areas
around the joint with a coat of paint just thick enough to protect the
assembly from corrosion and add the tube to your list of items to be
inspected on both preflight inspections and annual condition
inspections. If
cracks are seen, replace the assembly before flying the aircraft. Even
if no cracks are seen, we advise that you install a reinforcement kit
on the tubes prior to continuing operation of the aircraft. This kit
is part number 35015.000 and may be purchased from SkyStar for $59.95. If you have any concerns or questions regarding this inspection, please call our Customer Service Department at 208-454-1443.
