The work platform provides plenty of work space for engine maintenance, but
some mechanics have a bad habit of leaning on the engine’s bleed air tube when
Flling the engine with oil.
That’s not good because the bleed air tube is made of light aluminum and it can’t
take your weight. It breaks!
One more thing: If you break the tube by leaning on it, the engine starter shroud
will break also. You can’t start the engine with a broken starter.
S
liding
the
hydraulic
deck
pylon door forward on your
Black Hawk was a no-brainer
for a long time.
Things have changed. Now
you must
think
before you slide.
Since the installation of the
SATCOM antenna on the pylon,
shoving the door past the door
stop on some birds is a no-no!
When the door catches on
the doorstop,
stop!
Don’t slide
it forward any farther until you
disconnect the antenna cable
connector, NSN 5935-01-269-
5305. If you push the door past
the stop, you’ll rip out the wire
from the cable cannon plug. If
that happens, you’ll knock out the
A2C2 satellite communications
panel in the bird.
So the next time you head
topside
on
your
bird,
pay
attention to the stenciled wording
on the pylon door that tells you
to disconnect the antenna before
sliding the pylon forward.
While you’re working around the engine, it’s also a good habit to keep your feet
off of other engine parts like the chip detector, the alternator stator, and the hydro-
mechanical unit connectors.
Always keep in mind during engine maintenance that your weight and your feet in
the wrong place downs your bird and creates unnecessary maintenance for the engine
shop.
