i. Install floor tunnel plate and trim covers as follows:
(l) Install floor tunnel plate and secure with attachment screws.
(2) Fasten tunnel carpet into place.
(3) Replace rudder trim covers and rudder trim knob.
j. Install front seats and rear seat bottom on floor panel.
2. Install either aft stabilator control cable as follows:
a. Route cable around its pulley located either over or under balance arm of stabilator.
b. Connect cable to stabilator balance arm and secure with bolt, washer, nut, and cotter pin. (Ensure
bushing is installed with bolt.)
c. Connect cable to forward cable at turnbuckle in aft section of fuselage. Upper aft cable connects to
right forward cable and lower cable to left cable.
d. Install cotter pin cable guard at pulley, where required.
e. Set cable tension and check rigging and adjustment.
f. Install seats and access panels.
RIGGING AND ADJUSTMENT OF STABILATOR CONTROLS
1. Level airplane. (Refer to chapter 8.)
2. Check and set correct degree of stabilator travel as follows:
a. Check stabilator travel by placing a rigging tool on upper surface of stabilator as shown in figure
27-l6. (This tool may be fabricated, for dimensions, refer to chapter 95.)
b. On a bubble protractor, set number of degrees up travel as given in figure 27-15 and place it on
rigging tool. Raise tralling edge of stabilator and deterrnine when stabilator contacts its stops,
bubble of protractor is centered.
—NOTE—
The stabilator should contact both of its stops before control
wheel contacts its stops.
c. On protractor, set number of degrees down travel as given in Figure 27-l5 and again place it on
rigging tool. Lower trailing edge of stabilator and determine when it contacts its stops, bubble of
protractor is centered.
d. If stabilator travel is incorrect in either up or down position, remove tall cone fairing by removing
attaching screws and with use of rigging tool and bubble protractor, turn stops located at each
stabilator hinge in or out (refer to figure 27-l5) to obtain correct degree of travel.
e. Ensure that lock nuts of stop screws are secure and reinstall tall cone fairing.
3. Check and set stabilator control cable tension as follows:
a. Ensure that stabilator travel is correct.
b. Remove access panel to aft section of fuselage.
c. Secure control column in near forward position. Allow 0.25, +0.l2-0.03 inch between col- umn
and stop bumper.
d. Check each control cable for correct tension as given in figure 27-l5.
e. If tension is incorrect, loosen turnbuckle of lower cable in aft section of fuselage and adjust
turnbuckle of upper cable to obtain correct tension. Cable tension should be obtained with control
wheel at 0.25, +0.12-0.03 inch dimension from stop and stabilator contacting its stop.
