Dear Sergeant D. H.,
To protect the LCD panel,
otherwise called the optical
window instrument, and save
maintenance costs, order a
LCD panel cover with NSN
That
should cover the problem.

HGU-56/P AIHS…
ALSE
techs, the HGU-56/P
aircrew integrated helmet sys-
tem (AIHS) visors can get
stuck quickly because desert
sand clogs the guide tracks of
the visors.
Crews can’t resist pulling on
the helmet knobs to force the
visors down. That can break
the helmet knobs and then the
helmet is NMC until your
ALSE shop replaces the visors.
To keep visors operating
smoothly, use low pressure air
to blow out sand and grit. Or
use a pipe cleaner to remove
any gunk.
‘Course, in a desert environment, helmet PMCS should be done
more often
than
what it says in Para 3-3 of TM 1- 8415-216-12&P to reduce stuck visors. It is each
soldier's responsibility to clean their visors and do daily PMCS.

UH-60A/L/Q…
Dear Rotor,
Our Black Hawk unit recently received
AN/ARC-220 high frequency radios.
After a few months, we noticed small
cracks and dark blemishes on some of
the LCD displays in the center control panel.
This is the result of careless slinging,
dropping and flipping of the seat belt to the
left after unfastening the buckle.
After too many hits,
the LCD panel becomes
unreadable. Replacing
the ARC-220 high
frequency control
costs the unit $5,287,
minus the $2,882
unserviceable credit.
We pay a whopping
$2,405 every time the
ARC-220 HF radio
control head, NSN
gets damaged.
SSG D. H.
1022 Med Co.
Cheyenne, WY
you damaged
my an/arc-22o
lcd panel.
sorry, I
forgot to
cover
your lcd
panel.
Do not drop
or sling belt
on LCD panel
Place cover on
LCD panel for
protection
—stuck visor, right?
I’ve told you hotshots
that desert conditions
will require you to clean
your helmets more often
than the tm says…
your mission’s
over, but you
shouldn’t
have
slung your
seatbelt!
