Dear Editor,
The fire extinguisher bracket for the UH-1H helicopter is NSN 4210-
00-933-2929 according to TM 55-1520-210-23P. The FED LOG-AMDF
shows the NSN as inactive-deleted with-
out replacement. However, the FED LOG-
FLIS (the DOD item manager) lists NSN
4210-01-183-4822 as its replacement.
This replacement is too small to work
without major modifications that
include the addition of a strap. Even
then, it’s a safety hazard because the
fire extinguisher can’t be quickly removed
in an emergency.
I solved the problem by using the
bracket, NSN 4210-00-106-6464,
which is used on the UH-1M helicopter.
It works on the UH-1H with no
modifications.

echanics, when you’re working on your Chinook’s rotor heads, don’t block
out the need for servocylinder safety blocks, NSN 1730-01-264-6254. They
provide safety and stability.
Crew chiefs, make sure the blocks are used, and used the right way. That
means the blocks are installed for each job they’re
called for, and remain installed until the job is
done. It also means retracing the equipment condi-
tion task trail to its start to make sure the blocks
are removed when the job is done.
When a block is installed, it must be put on the
piston with the slot of the block outward and the
latch up. Just dropping the locking latch in place
won’t cut it—you have to
tighten the screw to hold the
latch down.

You’ve shown why it’s important to follow the info in the FED LOG-AMDF.
The Army does not always approve an item manager’s replacement NSN.
The NSN you list for the bracket that works is scheduled to appear in the
next change to the TM. Good work!
