ecause the M240H machine gun has replaced the M60D on all Army aircraft, the
UH-60 and CH-47 gun mounts have been adapted for the M240H.
In PS 678 (May 09), we gave
you the NSNs for the UH-60/CH-47
M240H solid mount assembly, the
M240H solid mount assembly parts,
the
CH-47
M240H
machine
gun
rear ramp mount assembly, and the
M240H solid mount assembly pintles
and associated equipment.
A copy of the PS 678 article with
the NSNs is available online:
archives/PS2009/678/678-36-37.pdf
PS 679 (Jun 09) listed the NSNs
for the ammo can elastic cord, NSN
4020-01-534-6786, and for the brass
defector, NSN 1005-01-534-8844.
At that point there was no NSN for the cradle spacer that bolts to the cradle
and forms a funnel-type collar between the base of the M240H and the cradle. Now
there is: NSN 5340-01-562-7406. It comes with four mounting bolts and washers.
The spacer prevents rounds from bouncing back into the ejection port and jamming
the M240H.
W
ith Soldiers deploying and redeploying,
there is one item that should
never
go into a
duFfe bag: your HGU-56/P aircrew integrated
helmet system (AIHS). It should always be
carried in its helmet bag.
Pilots and copilots, your helmet should go
with
you
on commercial or military fights as
a carry-on item.
Putting the helmet in your duFfe bag is a
disaster waiting to happen. No helmet can
survive the rough handling that luggage goes
through. You may think the helmet is protected
by clothing in the bag, but by the time the
duFfe bag reaches its destination, aFter being
thrown around by handlers, you can bet your
helmet will have voids, splits and broken
ear cuffs.
It costs about $1,100 dollars to replace a
beaten, battered and broken helmet and either
you or your unit will deal with purchasing a
new one.
You can’t fy iF you don’t have a helmet For
your noggin. So be safe rather than sorry and
take the helmet with you as a carry-on item.
The collector assembly (NSN 1005-01-534-6803, PN 13010666) uses only empty
cartridge bag (NSN 1005-01-536-5652, PN 13010672). They are items 2A and 3A in
Fig 15 in TM 9-1005-262-23P.
The case collection frame
assembly
(NSN
1005-01-
562-9456,
PN
13019575)
uses only empty cartridge
bag
(NSN
1005-01-563-
8450, PN 13019585). They
are items 2 and 3 in Fig
15. You can’t interchange
the cartridge bags between
the collector assembly and
the case collection frame
assembly.
Maintenance information for the M240H mount is found in TM 9-1005-262-13
and parts inFo in the -23P. Both are available on the LOGSA ETM site:
