10.4 RUDDER BALANCE
The rudder is balanced at the factory during assembly and unless the rudder is damaged
the balance should not change. If the rudder is found to be unbalanced outside the
specified limits cause for this condition should be ascertained before proceeding.
To balance the rudder it must be removed from the aircraft. Balancing is done around the
rudder hinges with the hinge pin line horizontal and on the high side of the rudder. The
balance weight takes the form of a epoxy resin and lead shot mixture set inside the
leading edge of the rudder horn. The balance should be changed by either removing lead
or adding to this mass with a similar mixture. The hinge moment can be measured using
masses on the trailing edge or by measuring the force needed to maintain the rudder
for/aft centreline horizontal.
Weight and moment values are given below:
Weight
2200g
+/- 100g
Hinge Moment
