CHAPTER 27-20
FLIGHT CONTROLS - RUDDER AND TAB
1. General
The DA20-C1 has the usual rudder control system. Each pilot has a rudder pedal assembly. The
pilot can adjust the pedal position. Control cables connect the pedal assembly to the rudder. A
fixed trim tab gives a small amount of adjustment to the rudder trim. You can only adjust the fixed
trim tab on the ground.

2. Description
The DA20-C1 has a set of rudder control pedals for each pilot. The pedal assembly can be
adjusted. Figure 1 shows you the rudder control system. Figure 2 shows you the rudder pedal
assembly. The system has these parts:
− A rudder pedal assembly for each pilot at the front of the cockpit. The forward part of each
pedal connects to a brake master cylinder (Chapter 32-40).
− An adjuster for each pilot attached to the aft face of the rudder pedal assembly.
− A yoke (lever) assembly in the center of the fuselage behind the seats. The yoke attaches to
the bottom of the B-bulkhead.
− A rudder lower mounting-bracket at the rear of the fuselage. The rudder attaches to the
mounting bracket.
− Cable assemblies.
Six bolts attach each rudder pedal assembly to the cockpit floor.
Each rudder pedal assembly has two pedals. Each pedal has a lever and a foot pad. The pedal
has an “S” shaped tube. The lower part of the “S” shaped tube aligns with the pivot of the pedal.
The upper part of the “S” shaped tube aligns with the foot pad of the pedal.
Four control cables (‘Cockpit cables’) go from the firewall to enter the bottom of each “S” shaped
tube. Each cable goes through a tube and comes out at the top. Each cable goes from the pedal
assembly to the yoke in the center fuselage.
Each outboard control cable goes through teflon tubes in the aft face of the floor panel. Each
