The majority of the leaks appear at the
input
and
output
Fttings
on
the
±DA’s
check valve. But you also need to eyeball
the input and output Fttings for the supply
and crossover valves. All three of these
valves are made of brass and are prone
to
stress
corrosion
cracks
that
let
fuel
leak out.
If enough fuel builds up under the ²oor
plates, you and other crewmembers can be
exposed to concentrated fuel vapors that can
make you sick.
Before you inspect, be sure to drain the hull
following the general cleaning instructions
in your vehicle’s -10 manual. If no leaks are
found, continue your mission. But make sure
you check the valves regularly as part of your
before-operation PMCS. If you Fnd a leak,
tell your mechanic.
He’ll
contact
General
Dynamics
Land
System
(GDLS)
Contractor
Logistics
Support (CLS). They’ll send a CLS team to
remove and replace the leaking C7 ±DA with
a new, stainless steel version.
T
he mission is finally over and
you want to grab a quick shower
before heading to the chow hall.
But before you crawl out of your
Bradley, think a second.
Did you remember to turn off
the radios? How about the lights
and other electronic gear?
If you forget, those items can still pull power
from the batteries. And if your vehicle sits a while,
you might come back to dead batteries.
Even worse, you might not notice that the radios
were left on. And if you start the engine with the
radios on, a power spike could damage them.
So don’t forget: A complete shutdown includes
all electronics, too.
