rew, the required inspections of your AH-64 are not afterthoughts. Saying, “Oh,
I’ll get to it next time” won’t cut the mustard.
Here’s the problem. Pitch change (PC) link inspections must be done closely to
detect problems. That means inspecting the link assemblies daily during pre-flight
like it says in seq. no. 8.4 and 8.5 of TM 1-1520-251-PMD.
A PC link inspection should not be a quick and dirty look or done on a “now and
then” basis. If you don’t eyeball the links closely, it could mean trouble for you or
worse, your bird.
Bearings wear out over time and the spherical bearing will fall out of the outer race
because of wear.
Every day, check the pitch change link assemblies, NSN 1615-01-257-5795, for
excessive wear and damage.
p
ilots and crews, the question about whether you can or cannot paint your integrated
helmet and display sight system (IHADSS) is settled.
No
matter
how
badly
you
desire to paint your helmet like
Picasso, you’re not authorized to
do anything but touch-up painting.
Use only touch-up paint, NSN 8110-
01-331-6113.
Besides no freelance painting,
you can’t put stickers or decals on
the helmet either.
Now here’s why you can’t do
what you want to your IHADSS
helmet.
The helmet uses paint that has
speciFc infrared characteristics that
interfaces with technology used in
the IHADSS system in the cockpit.
The helmet’s paint has special heat absorption and reflection characteristics and if it’s
degraded in any way, your helmet’s performance is degraded as well.
So touch up only and leave stickers and decals alone. Make a note of the NSN change
until the next change to the TM.
If your complete visual inspection turns up something, call your AVIM shop so
they can do a more thorough inspection.
Remember to also inspect the link assemblies every 25 hours/14 days and during
routine phase maintenance.
AH-64D…
All Is
Not
Well
Until You Inspect
AH-64A/D…
No Helmet Painting!
Check PC links for excessive wear and damage
it’s
that
time
again!
yeah, yeah!
I know I need
to eyeball your
pc links before
you fly.
don’t
worry,
he’s
got it!
Only touch-up painting is authorized
no deal,
soldier!
you’re
only
authorized to do
touch-up painting.
hey sergeant
blade, check my
painted helmet!
