Crews,
soft spots
in
your HGU-56/P
aircrew
integrated
helmet system
(AIHS) mean your noggin
isn’t
fully protected.
I may be
tough,
but I’m
not made
of steel!
In the event of a
crash, a soft spot
may
not
offer you
the full impact
protection and
place your head at
risk for injury.

Since you
can’t
see
soft spots, the
aviation life support
equipment (ALSE)
headshed is adding a
check for soft spots
to the ALSE tech’s
120-day inspection
on page 4-3 of
TM 1-8415-216-12&P.
this kind of
abuse
can create
soft spots
on my
hard outer shell.
“I don’t know which
is the worst: being
dropped…”
“…forgotten
on a hot day…”
“…tossed in
the back…”
“…or being used
as a stool!”
1.
Place the palm of your hand against the shell so you
can press on the suspected soft spot with your index fin-
ger. Use the flat part of your finger, not the tip.
2.
If a spot is detected, use a coin the size of a quarter or
larger and tap around the area to find the extent of the soft
spot. The noise will sound dull or flat on the soft spot.
3.
Mark a circle around the edge of the soft spot with a
fine-tipped marker.
4.
Turn it in to your ALSE tech for evaluation.
Here’s
how to
check a
