Maintenance Material Control Maintenance material control is the heart of the AIMD. It is tasked with the accomplishment of the overall production effort. It is responsible for repairing aircraft and related support equipment at the intermediate level of maintenance. There are two control centers under maintenance material control—production control and material control. PRODUCTION CONTROL.—Production con- trol schedules workloads and coordinates production. It ensures the efficient movement of all aircraft or parts through the AIMD activity. Production control ensures maximum use of personnel and material resources. Production control has many functions in an AIMD, but its  main  responsibility  is  to  manage  resources efficiently. MATERIAL CONTROL.—Material control within a maintenance organization is responsible for parts and material used in the activity. Material control ensures that parts and materials are ordered and received. Once parts or material are received, they are routed to the applicable work centers and are not allowed to accumulate. Supply The supply support center (SSC) of an AIMD is responsible for receiving all parts and materials ordered. SSC prepares the requisitions and picks up and delivers the material to the various AIMD work centers. If maintenance is being performed 24 hours a day, the supply support center will be open 24 hours a day. This allows for a quick response to the work centers' material needs. Organizational/Operations Maintenance Division (OMD) An  organizational  maintenance division (OMD) is normally established in an AIMD. Specific authority has to be granted to combine the organizational maintenance divisions and the intermediate maintenance activities on board a naval air station. Not all AIMDs will have an organizational maintenance division.  An  operations  maintenance  division  is normally established when there is four or less aircraft assigned. OMDs on board a naval air station are responsible for all organizational-level maintenance that must be performed to their assigned aircraft. Power Plants Division The power plants division performs all of the three-degree gas turbine engine repairs. The three-degree repair program is divided into first-degree repair, second-degree repair, and third-degree repair. The program covers all gas turbine engines, their accessories, and components. This includes aircraft engines, auxiliary power units, and airborne or ground starting units. Airframes Division The airframes division has responsibilities associated with the Hydraulic Fluid Contamination Control Program. The division fabricates and tests hoses, tubes, and sheet metal parts for aircraft structural components. The division is responsible for the recertification of aeronautical equipment welders. The division is responsible for nondestructive inspection (NDI), aircraft tire/wheel maintenance safety, and corrosion prevention/control programs. Avionics Division The avionics division tests and repairs electrical and electronics system components. The division is responsible for calibration of precision measuring equipment (PME) and for ensuring that personnel performing calibrations are qualified and trained. Corrosion prevention/control of avionics equipment, maintenance, and the safety of aircraft batteries are also the responsibility of the avionics division. Armament Equipment Division The armament equipment division is responsible for testing and repairing airborne weapon systems. This includes calibrations, cleaning, corrosion control, preservation, and storage programs. Aviation Life Support Equipment Division The aviation life support equipment division is responsible for the Aviator's Breathing Oxygen (ABO) program, which includes surveillance, contamination, and handling. The division is responsible for the maintenance of the egress, air-conditioning, and pressurization systems. Survival equipment for the aircraft and aircrew is another function of the division's responsibilities. 2-6
