18-60 Tail Rotor Blade Rigging (continued)
11. If the blade angle range for left and right pedal settings cannot be obtained using the
preceding steps, pedal total travel is either too great or too small. Use the following
procedure to check and adjust pedal travel:
a. Add right and left pedal blade angles together. If total is less than 34.0°, pedal total
travel is too small. If total is greater than 35.5°, pedal total travel is too great.
b. If pedal total travel is too small, increase C343-11 push-pull tube length and/or
decrease C343-13 push-pull tube length.
c. If pedal total travel is too great, decrease C343-11 push-pull tube length and/or
increase C343-13 push-pull tube length.
d. Recheck left and right pedal blade angles per previous steps.
12. Balance tail rotor per § 18-20.
