rews, don’t leave your AH-64’s environmental control system (ECS) covers half
secured or you’ll lose them to aircraft rotor wash. And they become FOD.
Fully secure all cover turn lock fasteners on both the right and left side of your
bird. Rotor wash can break off unsecured covers.
It’s important to get them tight because if sand and dirt get in the ECU con-
densers, the exhaust fans stop working and won’t cool the ECS system. Then the
ECS system gets hot and creates failure messages on the multi-purpose display
panel (MPD).
Cover yourself by making sure all ECS covers are in place, tightly secured and
not hanging off. You’ll stay cool in your bird.

Light Repair By the Book
M
echanics, if the searchlight or landing light on a Chinook isn’t working, don’t do
more than you’re supposed to while to fixing it.
Get your TMs out and do your AVUM inspections and troubleshooting. Don’t do
AVIM work!
If you have to remove landing
lights or searchlights to turn in to
AVIM, follow the TM proce-
dures to remove them.
Don’t
cut
off the light’s terminal lugs
because it’s quicker to get the
light out than removing all seven
lugs from the terminal board.
Cutting the wires will cause a
longer turnaround time, longer
aircraft downtime and extra
repair work for the AVIM shop.
Do your AVUM mission, but
leave the AVIM stuff to AVIM.
Secure right- and
left-side ECS covers
my job’s
done
now that
your covers

Hey, since
you’re

lights…

gotta be
by
the book.
I know,
I know.
I
read
the book!

Remove light from bird like TM says.
No shortcuts!
sand or dirt
can’t get in and
