C. To check and adjust rudder travel, proceed as follows:
1. At a distance of 6.125 outboard of the aircraft centerline, (stabilator trim control rod), make
two small dots approximately six inches apart fore and aft, with a pencil, on the top surface of
the stabilator, both sides of the rudder and parallel to the aircraft's centerline.
2. Run masking tape on each stabilizer surface fore and aft with the edge of the tape placed at the
outboard side of the pencil marks.
3. Disconnect the rudder trim system at the lower end of the trim bellcrank at station 251.5.
4. With the small rod inserted into the trailing edge of the rudder, swing the rudder in both
directions to determine that the pointer intersects the inboard edge of the tapes. (Refer to
Figure 5-11.)
5. Should the pointer not intersect the inboard edge of the tape, adjust the rudder stops at the
rudder hinge bracket to obtain correct travel.
6. Ascertain rudder trim controls are properly rigged per Paragraph 5-31 and connect control rod
to trim bellcrank.
7. From the pilot's seat only, depress each rudder pedal completely and check for full deflection
of the rudder to each side.
8. Should the pointer not intersect the inboard edge of the tape, check for interference at the
rudder horn and the nose gear travel stops.
9. If interference is found at the nose gear travel stops, located at the bottom of the strut housing,
rework the stops until full deflection of the rudder in both directions is obtained.
NOTE: Maximum allowable nose gear travel is 25° degrees.
10. Check full travel of the nose wheel and rudder to determine that the rudder hits its stops just
before the nose wheel hits its stops.
