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.

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 paragraphs.

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

the sear link from restraint and lets the rack linkage function normally.

The BRU-14A bomb rack has a secondary release assembly. It initiates hook release if the LEMA fails to function. The secondary release assembly is a CAD that consists of a housing, piston, and release slider assembly mounted on the top of the bomb rack frame. When actuated, the secondary release moves the sear link

forward to release the bomb rack. The BRU-14/A doesn't have remote manual-release capabilities.
