ALSE techs, keep HGU-56/P aircrew integrated helmet system (AIHS) visor tracks
clean and you’ll avoid jams.
The visors have guides that ride in tracks. The build-up of dirt, sand and grit in
the tracks makes raising and lowering the visors difficult. It can also cause the visors
to bind or jump out of the tracks.
When the visors start sticking,
resist pulling on the right and left
actuating knobs. You’ll end up
breaking the knobs. Then the helmet
is NMC until you get new visors.
To keep your visors operating
smoothly, use low-pressure air to
blow away dirt, grit and sand. Or use
a pipe cleaner to get the gunk out.
But no lubricants! They attract dust
and leave a sticky residue.
’Course, you should also keep up
with the helmet PMCS in Para 3-3
of TM 1-8415-216-12&P.
Blow out dirt, grit and sand
