OH-58D Kiowa Warrior.
..
worn out or defective
accelerator stop lock on the
Kiowa Warrior’s M296 .50-cal
machine gun can let the gun fire
on its own during reloading.
That’s scary!
So check the accelerator stop
lock right now, armorers!
Lay
the stop lock on a flat surface. If
the bend of the stop lock is less
than .18 in. or greater than .25 in,
then the stop lock is bad.
If any of these conditions exist, the gun is NMC until you replace the lock.
Details on the lock inspection are in TACOM-RI MAM (Maintenance Advisory
Message)-00-009.
Get a copy from your local TACOM-RI LAR or contact Scott
Johnson, at DSN 793-2364, (309) 782-2364 or e-mail
johnson@ria.army.mil
. You
can also access MAMs on the Army Electronic Product Support web page. Go to
. If you don’t have a password, you’ll
have to request one.
After you get your password, log on
to and click on Safety First and scroll down
to Maintenance Advisory Msg or do a site search using the MAM number.
Check
all
accelerator stop locks, including new locks you have on hand. If you
have locks stamped with CAGE code 14677, Defense Supply Center Columbus
(DSCC) says do not use them! They’re defective.
Even though your PMCS in TM 9-1090-214-23&P tells you to check the accel-
erator stop locks quarterly, repairmen, you must now inspect them prior to reload-
ing and before and after each firing. Replace bad stop locks. Once the bad locks are
purged from the system, another MAM will be published ending the more frequent
inspections.
If you find other defective
stop locks, contact your LAR or Teresa Perry at the
Defense Supply Center in Columbus at DSN 850-3814, 614) 692-3814. Her e-mail
address is

we
won’t
be just
shooting off at
the
barrel.
good!
no more
uncommanded
firings without
warning!
We
hear
you.
we’ve
been
firing up a
storm, too.

Is it wedged against the sear?

Has it straightened out or lost
its allowable bend?
❏
Does it have improper bends?
❏
Is it twisted down and out?
