F. Cable Fittings
1. 100 Hour Standard Inspection
Check swaged terminal reference marks for any indication of cable slippage within fitting.
Inspect fitting assembly for distortion and/or broken strands at the terminal. Check that all
bearings and swivel fittings (bolted or pinned) pivot freely to prevent binding and subsequent
failure. Check turnbuckles for proper thread exposure and broken or missing safety wires/clips.
Pay particular attention to corrosion and "pitting" on cable terminals, turnbuckles and cable
fittings. Any corrosion or pitting found requires replacement of the corroded fitting and/or
cable.
2. 100 Hour Special Inspection
For airplanes 15 years old or older, using a 10X magnifier, visually inspect the entire surface of
each cable terminal, turnbuckle, or other cable fitting for corrosion or cracking. Inspect under
safety wire or clips wrapped around the cable or fitting. Any evidence of corrosion or cracking,
however minute, is cause for replacement. A logbook entry documenting the replacement of a
cable terminal, turnbuckle, or other cable fitting relieves the inspection requirement for that
fitting only, until such time as that fitting has been in service for 15 years.
