RIGGING AND ADJUSTMENT OF RUDDER CONTROLS.
1. To check and set the correct degree of rudder travel, the following procedure may be used:
A. Check the rudder travel by swinging the rudder until it contacts its stop. If the control cables are
connected, use the rudder pedals to swing the rudder.
B . With the rudder against its stop, place a rigging tool against the side of the rudder and vertical
s t abilizer as shown in Figure 27-13. (Ascertain that the tool is not contacting any rivets.) If no
gap exists between the rigging tool and the surface of the rudder and vertical stabilizer, the rudder
stop for one direction of travel is correct as required in Chart 2701. (This tool may be fabricated
from dimensions given in Chapter 91 .)
C. Swing the rudder in the other direction and check travel as directed in Step B.
D. Should the rudder travel be incorrect showing a gap between the tool and any part of the control
surfaces, the fairing should be removed and the stops reset to obtain correct rudder travel. (Refer
to Figure 27-15.)
2. To set cable tension and alignment of the rudder, the following procedure may be used:
A. Remove the access panel to the aft section of the fuselage.
B. Ascertain that the nose gear steering has been aligned and rudder pedals set fore and aft according
to Alignment of Nose Landing Gear, Chapter 32.
C. Clamp the rudder pedals to align in a lateral position as shown in Figure 27-12.
D. Adjust the turnbuckles in the aft section of the fuselage to obtain proper cable tension as given in
Figure 27-14 and to allow the rudder to align at neutral position. Neutral position can be deter-
mined by standing behind the airplane and sighting the rudder with the vertical stabilizer..
E. Check safety of turnbuckles.
3. Check that when the rudder contacts its stops, the clearance between the nose wheel stops and the nose
wheel horn is between 0.06 and 0.12 of an inch. A more accurate check can be made with weight off
of the nose wheel. Adjust the stops according to Alignment of Nose Landing Gear, Chapter 32.
4. Install the fairing and the access panel to the aft section of the fuselage.
