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.

soft spots, the
aviation life support
equipment (ALSE)
headshed is adding a
check for soft spots

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
