When
performing
the
gun-system
maintenance operational check (MOC),
dummy rounds are cycled through the
system and down to the gun. Instead of
cycling the dummy rounds through the
gun, leave the gun door open and let
them fall out into a container with a foam
cushion in it. This will keep your dummy
rounds in good shape. Don’t let them hit
the hard ground or they will get dented
and damaged. Since these rounds can be
hard to come by, it’s a good idea to keep
them in good shape so they can be used
for a long time.
Also, as a safety precaution, always stand clear of the turret and gun area during the
MOC. The turret and gun can rotate quickly, and if you are standing too close the barrel
flash suppressor will take you out at the knees.
M
echanics, when loading ammo into the AH-64 sideloader, it’s always a good idea to
load in auto mode. Loading in manual mode overrides the built-in safety functions of the
sideloader/magazine controller (SMC) and can result in a lot of damage if something is
forgotten (like leaving the function switch or the gate assembly in the upload position).
Before your next flight, ensure the latch
handle secures correctly and does not spin
when the armor side panel door is shut. If
you have a missing lock pin, install a new
hinge assembly, NSN 5342-00-134-3355, so
the latch handle knob stays out of the way of
the collective.
If auto loading fails and
you have to load in manual
mode, be sure to follow
the TM instructions exactly
as
written.
Also,
after
the mission is complete,
be sure to report the
problem so the sideloader
can be repaired and auto
loading is operational in
the future.
