(PIR-PPS50005-1, Rev. AF.)
CAUTION: VERIFY FREE AND CORRECT MOVEMENT OF RUDDER. WHILE IT WOULD
SEEM SELF-EVIDENT, FIELD EXPERIENCE HAS SHOWN THAT THIS CHECK IS
FREQUENTLY MISINTERPRETED OR NOT PERFORMED AT ALL. ACCORDINGLY,
UPON COMPLETION OF RUDDER RIGGING AND ADJUSTMENT, VERIFY THAT
THE RUDDER MOVES RIGHT WHEN THE RIGHT PEDAL IS DEPRESSED; AND,
THAT THE RUDDER MOVES LEFT WHEN THE LEFT PEDAL IS DEPRESSED.
a. To check and set the correct degree of rudder travel, the following procedure may be used:
1. 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.
2. With the rudder against its stop, place a rigging tool against the side of the rudder and vertical
stabilizer as shown in Figure 5-11. (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 Table V-II. (This tool may be
fabricated from dimensions given in Figure 5-21.)
3. Swing the rudder in the other direction and check travel as directed in step 2.
4. Should the rudder travel be incorrect showing a gap between the tool and any part of the
control surfaces, the tail cone should be removed and the stops reset to obtain correct rudder
travel. (Refer to Figure 5-13.)
b. To set cable tension and alignment of the rudder, the following procedure may be used:
1. Remove the access panel to the aft section of the fuselage.
2. Ascertain that the nose gear steering has been aligned and rudder pedals set fore and aft
according to Alignment of Nose Landing Gear, Section VI.
