MIL-STD-2088-SUP-2 Bomb Rack Unit BRU, Single Store, AircraftThis standard establishes the general guidelines and criteria for the design and development of a single store bomb rack unit BRU for carriage and release of airborne stores excluding air-to-air missiles from fixed wing and rotary wing aircraft using a single suspension point or suspension points spaced at 14 or 30 inches. This standard addresses detailed requirements for gravity non-ejected, pyrotechnic, hydraulic, and pneumatic powered BRUs. Mechanical aircraft armament interoperable interfaces are incorporated to enhance cross utilization and servicing capabilities between military aircraft and aircraft stores see 3.1 of all services of the Department of Defense DoD and North Atlantic Treaty Organization NATO nations.

b. The BRU shall provide for a non-hazardous means for an electrical functional check of the energy release control device. Troubleshooting and testing shall be conducted with the BRU mounted on the aircraft.

c. Removal and replacement of designated components without requirements for alignment and adjustment or special tools.

4.3.11.4.2 Intermediate maintenance. Design shall allow for maintenance tasks performed at this level to be confined to support of organizational activities.

4.3.11.4.2.1 Intermediate maintenance tasks. Intermediate maintenance tasks shall consist of the following:

a. Inspection: visual and dimensional inspections to determine corrosion damage and other defects reported by the organizational maintenance activity that would prevent re-use.

b. Repair by adjustment, servicing, and replacement of components, assemblies, and subassemblies not within the capabilities of organizational maintenance.

c. Checkout: electrical or mechanical functions.

4.4 Interchangeability. All parts having the same part number shall be functionally and dimensionally interchangeable regardless of manufacturer. The item identification, manufacturer's part number, and part number requirements of ASME-Y14.100 shall govern the part numbers and changes thereto.

4.5 Identification and marking. Identification and marking shall be in accordance with

MIL-STD-130. Nameplates for equipment identification shall be in accordance with MIL-DTL-

15024, Type A, C or H; Style III, Size 3 and MIL-DTL-18307. All parts shall be marked with part numbers and, if applicable, lot numbers. Specifications on engineering drawings shall provide for part marking and shall indicate location of marking for accessibility.

5. DETAILED REQUIREMENTS

5.1 Loading of stores. The BRU/store interface shall be designed with adequate space provisions to allow safe, rapid loading and off-loading of all applicable stores with a minimum of personnel, no peculiar equipment or tools required. This interface shall provide good visibility and easy access to all controls, connections, switches and devices that relate to store loading/off- loading operations and positive visual determination of status of store installation. Consideration shall be given to store handling equipment installation (including manual loading equipment) and vertical support/lug entry angle during loading/off-loading operations. BRU geometry shall provide for the proper application of existing non-permanent hoisting adapters, hoisting devices including manual loading equipment, and loading carts or trucks as specified herein. All loading
