MIL-STD-2088 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.

a. Aircraft on ground (with internal pressure generation) b. Aircraft on ground (with external pressure generation) c. Aircraft in flight (with internal pressure generation)

If a removable reservoir or accumulator is used, the procuring activity shall specify the maximum time for vessel removal or installation (shall be not greater than 4 man-minutes).

4.3.11.4 Maintenance plan. The BRU shall be designed to be maintained at the organizational and intermediate levels of maintenance.

4.3.11.4.1 Organizational maintenance. Maintenance tasks performed at this level will be confined primarily to servicing and checkout of the BRU and shall be performed on a day-to-day basis.

4.3.11.4.1.1 Organizational maintenance tasks. Design shall allow for maintenance at this level to consist of the following:

a. Preflight and post-flight operations such as visual inspection, cleaning, servicing, and mechanical checkout. The ejector system shall not require cleaning or servicing prior to 50 ejections or 30 days, whichever occurs first.

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.
