pins are marked with fluorescent red-orange paint for
easy visibility. When the hooks are latched, the painted
areas are aligned, as shown in figure 10-6.
Operation
Weapons are armed mechanically and released
either electrically or manually.
ELECTRICAL RELEASE.— The electrical
release unit is energized through the bomb rack elec-
trical cable assembly by a 28-volt dc power supply, which
is located in the aircraft’s weapons control system.
When power is applied, the release unit plunger strikes
the release bell crank Through the connecting link, the
sear link rotates to free the lock link As the hook latches
move forward, the hook springs and hook-latch springs
pull the suspension hooks open. The front hook comes
to rest against the hook stop, and the latches are
cammed-up out of engagement. The lock link is held
against the aft link by the lock link return spring.
MANUAL RELEASE.— The sequence for manual
release is the same as for electrical release, except that
the release bell crank is actuated by the manual release
cable. The manual release cable is routed from the
aircraft and connected to the manual-release cable
assembly of the bomb rack
ARMING.— A 28-volt dc power supply from the
aircraft’s weapons control system provides voltage to
energize the two arming solenoids. These solenoids
electrically control mechanical arming, The arming units
are energized individually or simultaneously. When the
arming units are energized, the arming wires remain in
place. The store is armed as it falls from the bomb rack,
When the solenoids are de-energized the store pulls the
wires free of the bomb rack, and it isn’t armed.

series bomb rack, refer to Bomb Rack Models Aero 65A
Series, NAVAIR 11-5E-50.
PENGUIN MISSILE LAUNCH ADAPTER
The MLA attaches to the left outboard pylon of the
SH-60 helicopter and provides mechanical attachment
points for the missile launch and release system. The
missile launch adapter is equipment with the BRU-14
bomb rack with AERO 1B adapters, which provide the
rack with 30-inch suspension.
MAU-38/A BOMB RACK
The MAU-38/A bomb rack mounts in the bomb bay
of P-3 aircraft (all models). The MAU-38/A bomb rack
(fig. 10-7) is a major modification of the Aero 65A bomb
rack. The frame is modified; there are only two aircraft
mounting bolt holes-one on each end of the frame.
Also, the release return and manual release linkage are
arranged on the right and left side of the rack frame,
respectively. The operation, suspension, and maximum
capacity of the MAU-38/A and Aero 65A bomb racks
are the same. However, you can’t use the Aero 1A bomb
rack adapter assembly on the MAU-38/A.
