6.
Remove tracking weights and span balance
weights as follows:
a.
Remove lockwire from screws (1). Remove
four screws (1) and washers (2) from tip
cover (3). Remove tip cover.
b.
Review balance weight adjustment required
(steps 2 thru 5). Recheck calculations for
accuracy.
Make sure that blade is level or
tip slightly higher than root end. If
weights slide out of tubes and become
mixed, weight reference will be lost.
c.
Remove forward tube end caps (4) and aft
tube end cap (5) as required.
NOTE
If aft tube weight adjustment is
required, add or remove weight from
upper tube first. If upper tube is full or
empty, use lower tube.
