uch like some people, the Army’s workhorse Black Hawk fleet shows age
by developing structural cracks.
But the condition of the airframe affects how your bird flies. So, in addition
to your daily pre-flight checks, give your bird an extra once-over for cracks.
Eyeball the right side bulkhead behind the gunner’s window, the inboard
panel behind the main landing gear struts, and the frames for the right and left
side sliding doors.
Go easy when closing those sliding doors, too. Slamming them too hard
can create more cracks.
If you find any cracks, fix ‘em according to your TM’s procedures.

rew chiefs, keep your Black Hawk’s NiCad battery going and going and going by
disconnecting it when you don’t need it.
If you forget to turn off the cockpit utility lights, the battery discharges. Then there
won’t be enough power to start the auxiliary power unit’s electronic sequence unit.
So save your bird’s battery by disconnecting it at the end of each work day.
Simply turn the battery connector counterclockwise until it detaches.
You’ll save a lot of headaches and avoid battery power drain.
A new MWO replaces the NiCad battery with a sealed lead-acid battery on all
Black Hawks. It’s wired differently to keep the lights from draining the battery.
