(1) Install the floor tunnel plate and secure with the attachment screws. Fasten the tunnel carpet
into place. Replace the rudder trim cover and the rudder trim knob.
J. Install the front seats and rear seat bottom on floor panel.
2. Either aft stabilator control cable may be installed by the following procedure:
A. Route the lower cable around its pulley located forward of bellcrank.
B. Connect the cable to the stabilator bellcrank and secure with bolt, washer, nut and cotter pin.
C. Connect the cable to the forward cable at the turnbuckle in the aft section of the fuselage. The
upper aft cable connects to the right forward cable and the lower cable to the left cable.

RIGGING AND ADJUSTMENT OF STABILATOR CONTROLS.
1. Level the airplane. (Refer to Chapter 8.)
2. To check and set the correct degree of stabilator travel, the following procedure may be used:
A. Check the stabilator travel by placing a rigging tool on the upper surface of the stabilator as shown
in Figure 27-16. (This tool may be fabricated from dimensions given in Chapter 95.)
B. Set on a bubble protractor the number of degree up travel as given in Figure 27-15 and place it on
the rigging tool. Raise the trailing edge of the stabilator and determine that when the stabilator
contacts its stops, the bubble of the protractor is centered.
—NOTE—
The stabilator should contact both of its stops before the control
wheel contacts its stops.
C. Set on the protractor the number of degrees down travel as given in Figure 27-15 and again place
it on the rigging tool. Lower the trailing edge of the stabilator and determine that when it contacts
its stops, the bubble of the protractor is centered.
D. Should the stabilator travel be incorrect in either the up or down position, remove the fin/ rudder
fairing by removing the attaching screws and with the use of the rigging tool and bubble protractor
turn the stops located at each stabilator hinge in or out (refer to Figure 27-12) to obtain the correct
degree of travel.
E. Ascertain that the lock nuts of the stop screws are secure and reinstall the fin/rudder fairing.
3. To check and set stabilator control cable tension, the following procedure may be used:
A. Ascertain that the stabilator travel is correct.
B. Remove the access panel to the aft section of the fuselage.
C. Secure the control column in the near forward position. Allow one-half + 1/4 inch between the
column and the stop bumper.
D. Check each control cable for the correct tension as given in Figure 27-15.
