For further information concerning the MAU-38/A
bomb rack, you should refer to Bomb Rack Model
BRU-12/A and MAU-38/A, NAVAIR 11-5C-23.
BRU-12/A BOMB RACK
The BRU-12/A bomb racks (fig. 10-8) are
MAU-38/A bomb racks that incorporate the AAC 571.
Part of the change includes the deletion of the remote
manual release capability (you can manually open the
rack during ground servicing), a double vice a single
release return spring, and replacement of the knurled
latch knob by a hexagon knob that requires the use of a
3/4-inch wrench. The BRU-12/A is interchangeable
with the MAU-38/A. It mounts in the bomb bay of all
models of the P-3 aircraft.
BRU-14/A BOMB RACK
The BRU-14/A bomb racks (fig. 10-8) are
suspension and release of conventional and special
weapons/stores up to 2,200 pounds with 14-inch
suspensions. At times, Aero 1A adapter assemblies are
used to increase the bomb rack to 30-inch suspension
capacity. The BRU-14/A is a major modification of the
Aero 65A-1 bomb rack. You may install it in the bomb
bay of the P-3C and S-3 aircraft. The major
modifications are discussed in the following
Sway braces are bolted to the rack frame.
Installation of an IFOBRL allows remote locking and
unlocking of the rack when electrical power is applied
to the aircraft.
The BRU-14/A bomb rack has an auxiliary unlock
assembly. It releases the IFOBRL if it fails to function
in the normal release mode. The auxiliary unlock
assembly is a cartridge-actuated device (CAD) that
provides a mounting point for the aft end of the
IFOBRL. When actuated, the unlock assembly releases
the IFOBRL and allows it to move forward. This frees
