elicopter repairers, out-of-sight, out-of-mind doesn’t play well when it comes to
maintaining and preserving your Black Hawk’s ESSS extended range fuel tanks.
Removed tanks should not be left out to roast in the hot sun or be left exposed to
bad weather. Leaving tanks outside makes them vulnerable to the elements and the
animal kingdom, like bird droppings. Rain and temperature extremes can damage
the tanks.
Weather changes can cause condensation buildup inside the tanks. And you know
corrosion will follow if the tanks aren’t properly preserved. Uncovered connectors,
plugs and fittings are openings for corrosion to attack.
Don’t treat them like leftovers from yesterday. When the tanks are removed from
the bird, give ‘em a healthy dose of proper PM like it says in Para 1-3-26 of TM 1-
1520-237-23-1. Don’t forget proper tank preservation, which is often not done like
the TM says.
Make sure you always store the tanks in a warm, dry area, covered and preserved
correctly by following the TM instructions to the “T”.

rew chiefs, don’t just eyeball
your Chinook’s flight control closet
during daily inspections.
“Look, but don’t touch”
just
won’t do. The closet is the brains of
your bird’s flight control functions
and hydraulic systems.
You should feel components for
leaks or missing parts, things like:
•
missing cotter pins
•
loose cannon plugs
•
leaking fittings
•
loose bolts and nuts
•
loose hydraulic lines
Eyeballing and
touching these
things during
daily inspections
can keep you
flying.
I gotta
do this if
you want
to fly
today.
Look, Feel
&
Touch
whatever
you’re
doing
inside of
me—
it
tickles!
