e. Control Cables. Aircraft control cables are
generally fabricated from carbon steel or corrosion-
resistant steel wire and may consist of either flexible or
nonflexible type construction.
(1) Control cable sizes. Cable size is
measured in diameter as shown in figure 9-18. Control
cables vary in diameter, ranging from 1/16 to 3/8 inch.
Figure 9-18 also shows common cable designations.
Cable designations are based on the number of strands
and the number of wires in each strand.
maintenance. Aircraft cable systems are subject to a
variety of environmental conditions and forms of
deterioration, such as wear, corrosion, and distortion.
The following are general procedures for control cable
inspection and maintenance.
(a) Inspect cables for broken wires by
passing a cloth along length of cable. Cloth will snag
when it passes over broken wire. Figure 9-19 shows
cross sections of a 7x7 and a 7x19 cable.
