9 Visually inspect each flight control cable exterior and
interior along its entire length for evidence of broken wires,
corrosion, fraying or other damage. Visual inspection may
be via direct sight, mirror and flashlight or borescope. Bend
and twist cable for proper inspection.
10 Inspect cable retracting springs connected to the pedals for
correct installation, corrosion or damage.
11 Check swaged terminal reference marks for an indication
of cable slippage within the fitting. Inspect the fitting
assembly for distortion and/or broken strands at the terminal.
12 Reattach the control cable to the rudder as per Installation
Paragraph.
13 Examine cable runs for incorrect routing, fraying, twisting,
or wear at fairleads, antiabrasion strips, and guards.
14 Inspect fairleads for wear, breakage, alignment, cleanliness,
and security. Examine cable routing at fairleads to ensure
that deflection angles are no greater than 3° maximum.
15 Inspect cable systems for binding, full travel, and security
of attaching hardware.
16 Visually check for proper routing along entire length of cable.
Make sure that cables and attaching sectors are free and clear
of airframe structure and other components.
17 Lubricate critical control cable areas with a light coat of
grease or general purpose, low-temperature oil (galvanized
cable only!).
