Identify  and  apply  analytical  techniques  to  areas of material deficiencies, high man-hour consumption. or  other  pertinent  trends. Provide  assistance  to  production  control  or maintenance/material  control  in  determining  material consumption and usage based on MDS or NALCOMIS reports  and  inquiries. Coordinate all MDR matters with the DSF. MAINTENANCE  MATERIAL  CONTROL.— The  maintenance  material  control  officer  (MMCO) exercises authority in a line position between the AMO and the production divisions. The MMCO is directly responsible to the AM0 for the overall productive effort  and  material  support  of  the  department. Maintenance material control normally has two work areas-one  for  maintenance  control  and  one  for material control. Maintenance   Control   Work   Center.—The maintenance control work center is usually referred to as  maintenance  control  or  the  maintenance  control office.   Maintenance   personnel   use   these   terms interchangeably,. Maintenance control is the nerve center of the maintenance department. The MMCO is its head. This officer, assisted by the maintenance control chief. directs the production divisions. He or she makes sure there is prompt movement of aircraft, parts.  and  materials.  The  MMCO  also  maintains liaison with the supporting activity to ensure that the department’s  workload  requirements  and  productive capability are compatible. Under his or her direction maintenance control personnel plan, schedule. and provide positive control of all maintenance performed on or in support of assigned aircraft. Material Control Center.—Material   control center personnel provide material and supply support to the department. An effective aircraft maintenance department  program  depends  upon  a  cooperative working relationship between production and supply. In the organizational maintenance department. the material control center acts as a liaison between the maintenance department and the local supply activity,. Personnel in the material control center make sure that  the  proper  parts,  tools,  and  equipment  are available  to  the  production  divisions  in  the  required quantity and at the proper time. Material control center personnel compile and analyze maintenance usage data. They furnish technical advice and information to the local supply activity on the identity and quantity of supplies. spare parts. and materials necessary for the assigned  workload. 1-8 PRODUCTION  DIVISIONS.—Aviation mechanics and technicians maintain naval aircraft and staff the production  divisions.  The  production  element  of  an O-level  maintenance  activity  consists  of  the  four divisions shown in figure 1-1. They may be subdivided into branches and sections to perform the required maintenance tasks more effectively. A discussion of the more important production divisions is presented in the following paragraphs. Remotely Piloted Vehicle (RPV) Division.—An RPV division (previously Target Division) is optional, and  may  be  established  when  responsibilities concerning the operation and maintenance of aerial or surface  targets  are  extensive.  The  RPV  division coordinates and completes periodic maintenance, inspections,  decontaminations,  and  rehabilitation  of assigned RPVs. Aircraft  Division.—The  aircraft  division  has several branches. The power plants branch is manned by Aviation Machinist’s Mates (ADS), who maintain aircraft power plants and their related systems and components. The airframes branch is manned by Aviation Structural Mechanics (AMHs-Hydraulics and  AMSs-Structures),  who  maintain  the  structural systems of the aircraft, landing gear, fuselage, etc. The aviation life support systems branch is manned by Aircrew  Survival  Equipmentmen  (PRs)  and  Aviation Structural Mechanics (AMES-Safety Equipment). PRs maintain  parachutes,  life  rafts,  emergency  equipment kits, and flight clothing. AMES maintain oxygen, pressurization, air-conditioning systems, and other emergency  equipment.  The  inspection  branch  is headed by an inspection supervisor who performs all maintenance control functions (except cannibalization)  of  aircraft  undergoing  a  phase inspection. NOTE:  Many  commands  have  a  permanent inspection work center that has one person of each rating  assigned,  as  necessary,  for  the  inspection process. In some activities, a temporary crew may be established. NOTE: All work centers have a responsibility for corrosion.  Additionally,  most  activities  may  have  a permanent corrosion work center staffed by personnel from several ratings. Avionics/Armament  Division.—The   avionics/ armament  division  has  several  branches.  The electronics branch  is normally manned by Aviation Electronics  Technicians  (AT[O]s)  who  perform organizational-level  preventive  and  corrective
