Note: Underbalanced (trailing edge heavy) conditions are corrected by adding
additional weight to the control surface. Typically, by placing additional
washers, lead or steel, under each nut or bolt head retaining the balance
mass, as required. A maximum of four washers per bolt and nut retaining
the balance masses and a maximum of three washers under any bolt head
or nut. Always place steel washer next to nut.
Overbalance (leading edge heavy) conditions are corrected by removing
small amounts of material from the lead balance mass, typically by drilling
or other means. Correction may also be accomplished by reducing the num-
ber of washers, used in retention of the mass balance. Observe all health
precautions when handling lead.
(k) Secure the total weight needed (to balance the aileron) to the aileron with bolts, flat wash-
ers, and new self-locking nuts.
(l) Install the aileron. (Refer to 57-50)
(m) Operate the aileron and inspect for any abnormal resistance. Correct as needed.
