variety of Kitfox™ aircraft kits were upgraded to stainless steel
rudder cables over the years. We have discovered that in some cases the
original un-plated Nicopress sleeves continued to be shipped despite the
change to stainless cables. This combination of stainless cables and
un-plated sleeves can lead to accelerated corrosion between the
if the rudder cables on your aircraft have the affected combination of
stainless cables and un-plated sleeves. A magnet can be used to
determine of your cables are galvanized or stainless; the galvanized
cables are strongly magnetic, whereas the stainless cables are only
slightly magnetic, if at all. The un-plated sleeves are copper-colored,
while the plated sleeves are zinc-colored.
your aircraft has the stainless cables and un-plated sleeves, before the
next flight, and at intervals not greater than every six months, inspect
your cables at every cable/sleeve junction for corrosion. Should any
evidence of corrosion be encountered, the cables and sleeves must be
replaced before the next flight.
of the apparent visual condition of the cables, the affected aircraft
must have the proper combination of stainless cables and plated sleeves
installed within three years from the date the cables were assembled.
