This
new
harness
will
replace
the legacy branched wiring harness,
NSN 6150-01-186-8601, by attrition.
Continue
to
request
the
legacy
harness. When stocks are depleted,
you will automatically receive the
new harness.
When you receive the new harness,
you will need assembly/disassembly
procedures for it. They are not listed
in
TM
9-1270-233-23&P
or
TM
1-1520-Longbow/Apache.
Y
our Black Hawk pilot and co-pilot seats are not designed to allow the full force of your body
weight to free fall into the seat.
When adjusting the seat
it is a good practice to sit in
the seat normally. Then move
your body around and lift your
body to adjust the seat.
Plopping into the seat, or
slamming onto or bouncing on
the seat to force adjustment
can break or bend the vertical
bracket under the seat. If that
happens, your bird is NMC
and the mission never gets off
the ground.
So, eyeball TACOM MAM 09-002,
Helmet Unit, Branched Wiring Harness,
for
the disassembly and assembly procedures. The MAM also lists materials and parts.
The instructions, Fgures and call-outs for this are also posted on the Air Warrior
web site:
The new wiring harness info includes procedures for replacing defective
parts. Replacing the harness is a Feld-level repair and can be tested with the
helmet operational level tester (HOLT), NSN 4931-01-534-1228. Check out the
manufacturer’s user’s guide that comes with the shipment.
ALSE repairers should use care when installing the sensor alignment scope on
aircraft with the new wiring. That’s because the electronic component assembly
has less clearance around the sensor scope mounting nut-plate. Over-tightening the
sensor scope screw could damage the circuit card housing and the card.
