PIPER CHEROKEE WARRIOR SERVICE MANUAL
4-63. BALANCING STABILATOR. (Refer to Figure 4-27.):
To balance the stabilator, the assembly must be complete including the trim tab, the tab push rod and
end bearing, stabilator tips and all attaching screws. Before balancing, tape the trim tab in neutral position
with a small piece of tape. Place the complete assembly on the knife edge supports in a draft free area in a
manner that allows unrestricted movement. Place the tool on the stabilator with the beam perpendicular to the
hinge centerline. Do not place the tool on the trim tab. Calibrate the tool as described in Paragraph 4-60. 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-II proceed as follows:
a. Leading Edge Heavy: Remove balance plates from the mass balance weight until the static balance
is within limits.
b. Trailing Edge Heavy: Add balance plates to the mass balance weight until the static balance is
within limits.
