3. Control Cable Inspection
Aircraft control cable systems are subject to a variety of environmental conditions and forms of
deterioration that, with time, may be easy to recognize as wire/strand breakage or the not-so-readily
visible types of wear, corrosion, and/or distortion. The following data may help in detecting the presence
of these conditions:
A. Cable Damage
Critical areas for wire breakage are sections of the cable which pass through fairleads and around
pulleys. To inspect each section which passes over a pulley or through a fairlead, remove cable from
aircraft to the extent necessary to expose that particular section. Examine cables for broken wires
by passing a cloth along length of cable. This will clean the cable for a visual inspection, and detect
broken wires, if the cloth snags on cable. When snags are found, closely examine cable to
determine full extent of damage.
The absence of snags is not positive evidence that broken wires do not exist. Figure 1A shows a
cable with broken wires that were not detected by wiping, but were found during a visual inspection.
The damage became readily apparent (Figure 1B) when the cable was removed and bent using the
techniques depicted in Figure 1C.
