echanics, a day in the desert is really hot, sometimes lim-
iting maintenance that can be done. Aircraft parts, tools and
the airframe exposed to the sun can get hot enough to fry you.
So when you’re doing split maintenance operations around
the clock, use as much protective clothing as possible.
If you don’t, you could suffer burns to your skin when
grabbing a tool or touching a hot airframe or aircraft part.
And make sure you take plenty of breaks in extreme heat
and drink plenty of water.

Back AGPU Up Right
A
lmost every crew chief or mechanic has used an aviation ground power unit
(AGPU). So think back. Did the AGPU have a bent or damaged drawbar, tongue
assembly and axle, or even a broken pivot bolt?
Some believe that sharp vehicle turns made at less than the prescribed radius is
the problem. Others believe that the pintle of the tow vehicle is too tall and it holds
the drawbar up at too sharp an angle or that careless backing is the cause.
There seem to be all kinds of causes, but the best solution to this problem is sim-
ple—
Never back the AGPU with any vehicle!
The AGPU is self-propelled, but it’s quicker to pull it with a tug to those distant
aircraft on the flight line. When you get to the bird, always maneuver and position
the AGPU using onboard power. When the AGPU must be backed up, the operator
should do it using AGPU power—not a vehicle.
As a reminder, stencil a
CAUTION–DO NOT BACK WITH VEHICLE
on the
front, upper-left side of the AGPU on the opposite side from the fire extinguisher.
This will remind tug drivers not to back up!
back me up
to that bird
under my
own
power!
that’s
right!
I don’t need no
vehicle to do
my backin’ up!
yeah, yeah.
cool your
exhausts…
…I
know
you’re self-
propelled.
Dear Sergeant Blade,
I’m an ALSE tech on the Apache IHADSS
helmets. Are there any approved AVUM test
sets for the IHADSS helmet?

Dear SGT J. B.
There is no unit test set for the IHADSS helmet.
The only testing that’s done is to boresight the hel-
met to the aircraft and to the 30mm gun with the hel-
met display unit (HDU) attached, like TM 9-1270-
223-23&P says. Unit maintenance and PMCS for
your IHADSS helmet is just what’s listed in the TM.
Check TM 9-1270-223-23&P
for info on helmet care
IHADSS Helmet Test Set?
TOO

hot to handle!
All Aircraft…
Black Hawk T700 Engines Needed!
Mechanics, T700 engines are in short supply! But you can help. Turn in all unserviceable
engines right away. And then the supply system can get them repaired and have serviceable
engines on hand to keep your aircraft mission ready. Please expedite unserviceable engines
through normal retrograde channels.
