Inspecting Rocket Components
As the rocket components are removed from their
shipping containers, inspect them by performing the
steps listed below. Dispose of defective items according
to current directives. The components you inspect
include launchers, warheads, fuzes, and rocket motors,
to include their fins.
WARNING
To avoid personal injury and equipment
damage in an operation involving assembly,
disassembly, fuzing, defuzing, or cleaning,
you must do the work in a designated area.
This area must be safely located away from
other explosives and vital installations. Only
the smallest number of rockets practicable
should
be
exposed.
Only
authorized
personnel essential to the work should be
permitted in the vicinity. Refer to the
publications
NAVAIR
16-1-529
and
NAVORD OP 3565 for RADHAZ pro-
cedures and precautions.
WARHEADS.Inspect the warheads as
follows:
WARNING
Warheads that are cracked or have a gap
between the fuze adapter and the warhead
are hazardous.
1.
Verify that the warhead is not cracked and no
gap exists between the fuze adapter and the
warhead.
2.
On the Mk 32 warhead, verify that the fuze is
staked.
3.
Verify that the base and fuze cavity threads are
not damaged or corroded.
WARNING
Do not use a warhead that does not have the
base fuze hole closed by a steel plug or a base
fuze. Base fuzes must not protrude more
than 1/16 inch. Detonation could occur
during handling or firing.
NOTE: Do not disassemble base adapters from
the warheads to check for base plugs.
4.
Verify that the warhead contains a base fuze or
a steel base plug. When installed, ensure the
base fuze does not protrude more than 1/16
inch.
FUZES.Inspect the fuze as follows:
WARNING
Fuzes that are damaged are hazardous.
Detonation may occur.
CAUTION
Do not use Mk 93 or M414 fuzes with nose
cones that are completely penetrated by
scratches, cracks, or abrasions. Minor
scratches or abrasions do not affect their
performance or safety.
1.
Verify that the fuze body is not damaged.
2.
Check
the
fuze
threads
for
damage
or
corrosion.
ROCKET MOTORS.Inspect the motor as
follows:
1.
Verify that the motor tube is not dented, deeply
scratched, gouged, or corroded.
WARNING
Use an authorized metal shielding band
assembly only. Do not substitute the Mk 71
motor plastic fin retainer band because it
offers no RADHAZ protection.
NOTE: Rocket motors packaged in individual
wooden containers may be received with the
old,
narrow,
metal
shielding
band
(P/N
1516140) installed. This band is obsolete and
must be replaced with shielding band assembly
P/N
4902192
when
unloaded
from
the
launchers.
2.
Verify
that
the
shielding
band
and
the
RADHAZ barrier are in place.
3.
Verify that the nozzle plug is in place.
4.
For rocket motor Mk 71, verify that the fin
retainer is in place, the fins are not bent or
broken, and the fin pin is clean and free of
foreign matter. The spring-loaded fins must be
exercised four to six times.
