rews, your aircraft tie-down chains, NSN 1670-00-516-8405, need as much PM as your
bird if you’re going to keep your birds anchored.
If you treat chains like a pile of junk, that’s what they’ll become. And if a heavy windstorm
blows up like it did at Ft Hood in 1989, your bird could be tossed like a chef salad if there
are weak links in the chain.
When you’re not using the chains,
don’t pile them up. Instead, stretch
them out to prevent dirt buildup and
to let them dry quicker. Chains left
in piles rust faster, especially in rainy
weather as water and dirt easily collect
in the chain pile. Then you’ll have all
the right ingredients for corrosion.
Check and clean corrosion from chains
like the tie-down TM says.
Frequently rotating the tie-down
chains you’re using extends their life
and use. Make sure the chain adjuster
lock mechanisms operate properly.
Chains that don’t ±t properly or are
not adjusted right will not provide
the right resistance to strong winds.
When you’re not using the adjusters,
store them in a safe place to prevent
damage from vehicles.
For all tie-down and mooring information, eyeball your bird’s -23 TM and TM 1-1500-
250-23,
Aviation Unit and Aviation Intermediate Maintenance for General Tie-Down and
Mooring On All Series Army Model AH-64, UH-60, CH-47, UH-1, AH-1 and OH-58 Helicopters.
If there are conflicts between your aircraft’s pub and the tie-down manual, the tie-down
TM takes precedence. Always use polyester rope. NSN 4020-01-318-5428 gets a
3

-in rope,
while NSN 4020-01-028-3843 gets a

-in rope.

Dear Editor,
Illustration 7G1X_00X101A for the
M261 rocket launcher stray current check
in TM 1-1520-Longbow Apache on EM
0126 shows the igniter arm in the raised
position for the stray current check.
Actually, the igniter arm should be in the
down (fire) position for the check. Please
let other aviation crews know so they can
correct their TMs.
