Fitting Your Helmet
If you have problems positioning the
ear cups so they align properly, try this:
Place a plastic sandwich bag between
each of the detached ear cups and the
harness.
That keeps the hook-and-pile
from fastening together.
Next, hold the ear cups and plastic bag
in place and fit the helmet on your head.
You’ll have to work the helmet and the
ear cup a little to make it fit properly.
Finally, when the helmet is centered on your head, and the cups fit your ears,
slowly pull out the plastic bags, one at a time, while holding the ear cup in place.
The hook-and-pile will fasten and hold the cups in the right position.
Putting It On
Go easy, ALSE techs, when you work on the visor tracks and the attaching
thumbscrews. They are delicate and you can easily strip the nut plate. Clean the
tracks like it says in Para 3-3 of TM 1-8415-216-12&P.

Microphone and Boom
When you’re done with the
microphone and boom, don’t just
shove them up into the helmet
liner. Store them along the side of
the helmet.
When you shove the assembly
up, the mike dings the liner. Any
dings or gouges

inch deep in
the front of the liner make the
helmet NMC. Then ALSE has to
replace the whole liner.
The microphone is held onto
the boom with a thumbscrew.
Hand tight is good enough to
keep it secure. If you overtighten
the thumbscrew, you’ll break the
mike and boom. Then you’ll have
a flapping mike, and you sure
can’t fly with one hand holding
the mike and the other on the
flight controls.
Dirt and sand buildup can jam
the helmet’s two visors in their
tracks. If they start to stick, don’t
get heavy-handed and pull on the
right and left actuating knobs.
You’ll probably break the knobs
or dislodge them from the visor’s
tracks. Let your ALSE shop
know if the visors starts to stick.

Here’s how
to put on
the helmet…
If you spread the helmet too much when putting it on,
you’ll weaken it, and that can lead to cracks.
1.
Hook your thumbs over the ear cups and spread the
helmet just slightly.
2.
Place the front edge of the helmet firmly against the
forehead.
3.
Rotate the helmet rearward and down onto your head.
4.
Press the helmet down firmly with both hands.
5.
Adjust the nape. When adjusting the nape straps, do
not pull on both straps simultaneously. Pull on one and
then the other in a see-saw motion for a snugger fit.
6.
Adjust the chin straps.
They can
blow out
the tracks
with shop
air to clear
the jam.
