Dear Sergeant Blade,
As you know, when maintenance is not taking place, we in the MEDEVAC
Black Hawk community crawl underneath our bird to gain access to the
sealed lead acid battery (SLAB), NSN 6140-01-286-6294, located
behind the access panel.
When the bird is not in use, it’s a headache to unscrew umpteen screws
from the bottom access panel just to disconnect the battery connector to
prevent a drained battery. It’s even worse when we have to put the screws
back in and then go back the next day to unscrew them again to reconnect
the battery connector. That’s a lot of time spent underneath the bird.
Dear Sergeant J
.J.
,
Looks like you’ve drained the battery drain problem. Before doing this procedure,
make sure you get your commander’s approval. Then include it in your unit’s
standard operating procedures (SOP).
Here’s our fix. Instead of
going underneath the bird, we
head to the cockpit center
console and pull the BATT
BUS and the UTIL LTS circuit
breakers. This will prevent
the SLAB battery from being
drained without having to fool
with the SLAB battery. We no
longer need to spend all that
extra time underneath the bird.
