4-59. BALANCING RUDDER. (Refer to Figure 4-21)
To balance the rudder, the assembly must be complete including the tip assembly with all attaching screws
and 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 centerline. Calibrate the tool as described in Paragraph 4-57. 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 in Table IV-I, proceed as follows:
a. Nose Heavy: This condition is highly improbable; recheck calculations and measurements.
b. Nose Light: This condition is caused by a light balance weight or a heavy rudder as a result of paint or
repairs. A light balance weight is highly improbable because it is enclosed in fiberglass per Figure 4-14, Section
A-A. Paint build-up must be stripped and surface repainted. If the rudder is too heavy as a result of repairs, the
repairs must be removed and damaged parts replaced.
