6. Remove stabilator control push rod from the fin by disconnecting attachment hardware at the balance
weight arm and at bellcrank.
7. Remove the two bolts at the leading edge of the fin.
8. Remove the eight bolts which secure the fin spar to the aft bulkhead. Remove the fin.
9. Install the fin in reverse of removal instructions. Check all bolts for safety. Refer to installation and
rigging of stabilator trim cable, and rudder cable for adjustment of cables.
RUDDER.
REMOVAL AND INSTALLATION OF RUDDER. (Refer to Figure 55-4.)
1. Remove the fairing.
2. Disconnect the rudder cables at the turnbuckles within the fuselage tail section and disconnect the
cable from the rudder sector.
3. While supporting the rudder, remove the hinge bolts and remove the rudder from the fin.
4. Install the rudder in reverse of removal instructions; check cable tension if disturbed.
BALANCING RUDDER. (Refer to Figure 55-5.)
To balance the rudder, the assembly must be complete including the rudder lower fairing assembly and all
attaching screws and the position light wiring. Place the complete assembly horizontally on knife edge
supports in a draft free area in a manner that allows unrestricted movement. Place the tool on the rudder with
the beam perpendicular to the hinge center line. Calibrate the tool as described in previous paragraph. Read the
scale when the bubble level has been centered by adjustment of the movable weight and determine the static
balance limit. If the static balance is not within the limits given, proceed as follows:
1. Nose Heavy: This condition is highly improbable; recheck calculations and measurements.
2. Nose Light: In this case, the mass balance weight is too light or the rudder is too heavy because of
painting; it will be necessary to strip the paint and repaint. If the rudder is too heavy as a result of repairs, the
repair must be removed and the damaged parts replaced.
