Rudder
(1)
Rudder control cables are routed from the left and right forward quadrants, under the flight deck and main cabin compartment floors. The cables pass through aft pressure bulkhead airseals into the horizontal stabilizer compartment, then up into the vertical fin. The cables are attached to the aft quadrant of the rudder feel, centering, and trim mechanism which uses control rods to operate the PCAs.
C.
Elevator
(1)
Elevator control cables start at the forward quadrants of the cable tension regulator; the left set is routed through the main cabin compartment ceiling. The right set travels beneath the main deck floor. Both sets pass through the air seals of the aft pressure bulkhead into the horizontal stabilizer compartment. The right set is routed up above the elevator feel unit and is attached to the lower aft quadrants. The left set of cables cross each other and they are attached to the upper aft quadrant on the elevator feel unit.

D. Stabilizer Trim
(1)
AIRPLANES WITH STAB TRIM LEVERS ON THE CONTROL STAND; the stabilizer trim cables start at the stabilizer trim arming and control levers of the P10 panel. The left side (control) cables are wrapped around the left lever's drum, while the right side (arm) cables are attached to the right lever's quadrant. Both sets are routed beneath the main cabin compartment floor, through air pressure seals in the aft bulkhead. The left set stops at the lower aft quadrant of the stabilizer trim control module; the right set stops at the upper left quadrant.
E.
Flaps/Slats
(1)
A single cable wraps around the drum of the flap control lever. One set of cables run aft on the airplane right side to the power drive unit of the trailing edge. A set of cables run from the aft side of the trailing edge power drive unit to the leading edge power drive unit. All cable runs are below the main cabin compartment and pass through air pressure seals in the sloping pressure deck into the main gear wheel wells. Cables for leading edge power drive unit pass through the wing root pressure seals.

FLIGHT CONTROL CABLES - MAINTENANCE PRACTICES
_____________________________________________
1. General_______
A. This procedure supplies flight control cable data to be used for reference purpose only. Refer to Chapter 27 Illustrated Part Catalog (IPC) for current cable part number, dimensions, materials and fittings. The figures that follow supply data for the flap, slat, aileron, rudder, elevator, and horizontal stabilizer trim cable systems. To remove or install a control cable, refer to AMM 20-10-03/401.
NOTE: You can mix zinc-only and tin-zinc coated cables but opposite
____ cable segments in the same cable loop must be of the samte type (example: in Fig. 202, cables A2A-2 and A2B-2 must be replaced together with both new cables either zinc-only or tin-zinc). This will prevent asymetric cable stretch that can make cable rigging bad.
