## What it covers

The system components and parts from the cockpit control to the stabilizer, except the actuator which controls position of the horizontal stabilizer for pitch trim (usually found on high performance turbine powered aircraft). Also for stabilator control systems on aircraft utilizing a single horizontal tail surface for both the stabilizer and elevator. Does not include structure in JASC code 5511. Typical parts are cable, bellcrank, pulley, control valve, indicator, etc.
