Q15.  What  level  of  maintenance  has  the  primary responsibility  of  supporting  and  supplementing the work of OMAs? Q16.  In  an  IMA,  what  work  center  controls  the department’s classified material? What unit in an IMA coordinates the screening of materials  and  parts  to  determine  repair responsibility  and  capability? Q17. SUMMARY The objective of the Naval Aviation Maintenance Program  is  the  achievement  and  continuous improvement of aviation material readiness and safety through the efficient use of resources. The governing directive  of  the  program  is  the  Naval  Aviation Maintenance  Program  (NAMP),  OPNAVINST 4790.2. OPNAVINST 4790.2 has five volumes. Of direct interest to the AZ is volume I of the NAMP, which outlines procedures for the organizational and the intermediate maintenance levels, and volume III of the  NAMP,  which outlines the Maintenance Data System (MDS). Rework  and  upkeep  are  the  two  types  of maintenance that are performed within the Navy. Organizational maintenance, intermediate mainte- nance, and depot maintenance are the’ three levels of maintenance that are used within the Navy. An  aviation  operating  unit  performs  daily organizational maintenance in support of its flight operations.  The  maintenance  department’s  mission within  an  aviation  operating  unit  is  to  maintain operating  unit  aircraft  in  a  state  of  full  mission capability. The maintenance officer is responsible to the  commanding  officer  for  accomplishing  this mission. The  maintenance  administration  work  center provides  clerical  and  administrative  services  to  the maintenance department. The quality assurance work center  has  as  its  objective  the  prevention  of  the occurrence of defects in maintenance. The  maintenance  material  control  officer  is responsible  for  the  overall  productive  and  material support   of   the   maintenance   department.   The maintenance control work center in an organizational maintenance activity (OMA) is the nerve center of the entire maintenance department. The material control work center in an OMA ensures that parts, tools, and materials  are  always  available  to  the  production divisions. The  intermediate  level  of  maintenance  supports and  supplements  the  work  of  an  OMA.  In  an intermediate   maintenance   activity   (IMA),   the maintenance administration work center controls the department’s classified material. The aeronautical material screening unit (AMSU) of an IMA coordinates the  screening  of  materials  and  parts  to  determine  repair responsibility  and  repair  capability. The role that an AZ plays in the Naval Aviation Maintenance Program is an important one. Regardless of your assignment, whether ashore or at sea, in a squadron, or in an aviation intermediate maintenance department, the concept of providing safe, reliable aircraft should be your primary objective. To meet this objective, the Navy relies on you, the AZ, to provide detailed,  exact  information. The references that are identified in this manual (in italic) are the references that you should use in your day-to-day tasks. When you are unsure about how to perform a certain tasks, never rely on your memory. Learn to use your references. Using your references should make your job easier and you will be respected for being professional and doing your job right the first  time. 1-13
