Rudder System

The rudder provides airplane directional (yaw) control. The rudder is of
conventional design with skin, spar and ribs manufactured of aluminum.
The rudder is attached to the aft vertical stabilizer shear web at three hinge
points and to the fuselage tailcone at the rudder control bell crank.
Rudder motion is transferred from the rudder pedals to the rudder by a
single cable system under the cabin floor to a sector next to the elevator
sector pulley in the aft fuselage. A push-pull tube from the sector to the
rudder bell crank translates cable motion to the rudder. Springs and a
ground adjustable spring cartridge connected to the rudder pedal assembly
tension the cables and provide centering force.
Yaw Trim System
Yaw trim is provided by spring cartridge attached to the rudder pedal
torque tube and console structure. The spring cartridge provides a
centering force regardless of the direction of rudder deflection. The yaw
trim is ground adjustable only.
A ground adjustable trim tab is installed on the rudder to provide small
adjustments in neutral trim. This tab is factory set and does not normally
require adjustment.

Control Locks

The airplane's control system is not equipped with gust locks. The trim
spring cartridges have sufficient power to act as a gust damper without
rigidly locking the position.
