echanics, to stop cable chafing and broken connectors in the right and left for-
ward avionics bays (FAB), give ‘em a little slack and protection.
When you inspect your Apache’s
FWD components, look for slack,
chafing and tight cable wire bundles.
If you locate problems, remove the
connectors and pull the slack out of
the cable to provide clearance. That
way the connectors are easier to
reconnect and won’t get damaged
from excessive pulling, which can
break connector pins and wires.
Since aircraft vibration and tight cables cause chafing, add a little extra cable pro-
tection by wrapping them with anti-chafe material, NSN 5970-01-143-6994. NSN
5970-00-617-1141 and NSN 9330-01-017-1440 are suitable alternatives.
Remember broken cables in the FAB mean the fire control computer, gun control
box, turret control box, or other components are NMC.
Also, when you perform aircraft run-ups, make sure there’s good air circulation in
the FAB. Just place your hand near the bay door vents and feel for airflow. If there’s
no airflow to cool the components, they will get hot and shut down. For the Apache
Longbow, check out the procedure in the IETM to ensure FAB components stay cool.
hey!
it’s
gettin’ hot
in my fab!
then we’d
better shut
you down
and check
it out!
yeah, and the
cables might
need some
attention, too!
Check for damaged, loose or tight cables

I am indeed
grateful to you,
thomas. pm will
be a benefit to
me and to
all
inventors.
in fact, I think we
should form a
partnership.
with
my
ideas and
your
knowledge of pm,
thomas, we could do
wonderful
things.
at night,
when the lid
is raised,
the bulb
lights up
and…
as a matter
of fact, I’ve
been thinking
about how your
light bulb
could be used.
imagine if
it were
installed in
a toilet!
