echanics, you know how important it is to inspect Black Hawk blade pins for
proper tension and security during the 10-hr/14-day inspection.
Well, it’s just as important to
allow enough time for the dry
film lubricant to dry on those
blade pins before you reinstall
them during the 500-hour
inspection. It usually takes
about 6 hours for dry film lubri-
cant, NSN 9150-01-260-2534,
to dry at 70°F. Then place the
pins back into the rotor head.
If you put the pins back in the blade cuff before the lube dries completely, it’ll act
like glue. The pins seize up and you won’t be too happy spending extra time
wrestling with a stuck blade pin at the next inspection.
To get a seized blade pin out, you’ll have to use a 6-in extension, a squirt of
WD-40 to loosen it, and a rubber mallet to tap it out. A blade pin that is seized in
the blade cuff must be replaced only if it’s damaged or dissassembled for removal.
Pay attention and don’t install blade pins in a rush just to get in some flight time.

history…
From this
moment
until time
is no
more…
…and soldiers who fight on the
battlefields of battles yet to
come will know that preventive
maintenance on our equipment
won us this mighty victory!
Oh, yes,
for I
pledge this
very day
that as my
family line
stretches
through
the ages
to come,…
…each member will
shout the word
about
preventive
maintenance
for
all
to hear.

h!!
Are you
