Dear Editor,
Our unit has the new HGU-56/P helmet. It’s a good helmet, but over
time the mike boom comes loose and swings away from the user’s face.
Instead of replacing the boom, make it tighter. Here’s how:
Remove the boom from the tightening assembly and cover the ball
with a

x

/

-in piece of shrink wrap, NSN 5970-00-814-2878.
Use needle-nose pliers to stretch the wrap around the ball and shrink
it to fit using a heat gun. Then trim off the excess, let the rest cool and
reassemble the microphone
boom. Problem solved.
This keeps the boom
assembly tight for a
long time—and is
better than scratching the ball with sandpaper to keep it tight.

Cargo to Rescue Mode Safety
C
hinook crews, be sure to pull 30 feet of cable from the spool
before
you
switch from the CARGO to RESCUE mode, on your Chinook’s internal winch.
Otherwise, as soon as you switch to RESCUE, the 3 feet of exposed cable,
along with its hook assembly, will quickly retract through the cable runner, then
under the floorboards and wrap around the spool. Anyone or anything unlucky
enough to be in the cable’s path will be hurt or damaged.
Avoid disaster—pull out
30 feet of cable
before
you switch to RESCUE.
That way you’ll be going
to the rescue instead of
being the one rescued.
