Dear Sergeant Blade,
After reading the story on
page 38 of PS 611 (Oct 03),
we think there might be a
potential problem.
The instructions to make
the tail rotor hardware dis-
play board do not allow for
the rotation of the tail rotor
which may happen while it is
disassembled.
If the tail rotor blades
being removed are to be
installed in the same gear
box, and the color bands
have worn off, use a grease
pencil and put index marks on
blades, retention plates,
pitch control rods, and pitch
beam so they are reinstalled
in the same clockwise and
inboard/outboard positions
to minimize rebalancing of the
tail rotor.
To maintain proper tail
rotor balance, it’s also
important to mark the board
with red, yellow, blue and
black labels as shown on the
retention plate. This will fur-
ther reduce hardware mixup
because if the rotor turns, it
ensures the hardware will be
installed in the same position
from which it was removed.
It’s also important that the
pitch beam, inboard retention
plate and outboard retention
plate and each pitch control
rod are marked with the cor-
rect color, too.
