tick a magnet or a knife in your ACU
pocket and take a walk to your AN/
ASM-189 and -190 electronic vans.
The van’s tailgate chain may have a
weak link and you need to Fnd it!
The last link of the chain–the one
that joins the chain to the tailgate–
might be aluminum. If it is, it just
might fail! This could cause a soldier
to take a tumble to the ground and
be hurt.
See if the magnet is attracted to
the link. If it is, the link is steel and
you’re in good shape. Or you can
use the knife and try to make a slight
scratch in the link. If it scratches easily,
it’s aluminum!
A link that is not welded closed is
another sure sign of trouble. Check all
the links for gaps.
Replace an aluminum link with a
steel riveted link, NSN 4010-01-218-
6340.
While you’re checking this last link,
check them all for rust and other signs
of weakness. You might want to run
that magnet over all the links just in
case. Only standard welded links and
the steel riveted hammer-lock type
that you should use as a replacement
link are authorized to be in the tail-
gate chain.
One other thing: don’t shoot yourself
in the foot by using tape or other bolts
to hold the support chain together.
Every link should be steel and strong.
The AN/TSQ-158, enhanced position location

are built and maintained by Raytheon Co.
Previously, these radios were repaired under a
repair and return program. This is no longer so.
If you have a non-working radio that needs to
be turned in to repair for depot level work, Fll
out a DD ±orm 1348 MILSTRIP requisition to
request disposition.
The item manager will then direct the RT
to be shipped to Raytheon using DoDAAC
CG001Q/RIC:C1G through the Army standard
supply system. They will include
a copy of the DD ±orm 1348 and
a completed DD-1149 and DA-
2407 or DA-5504. You’ll receive
unserviceable credit for the RT.
Submit a funded DD ±orm 1348
MILSTRIP for a replacement
radio. You’ll
be
charged
the
AMD± price for it.
If
you
have
questions
concerning this process, call the
EPLRS inventory manager at C-E
LCMC at DSN 992-1852 or (732)
532-1852. Or email:
