relationship  that  exists  between  an  advisory  staff supervisor  and  a  production  line  supervisor.  The concerns of staff personnel are with administrative service and support of the production effort. MANAGEMENT Management  in  an  aviation  maintenance organization   is   the  exercise  of  authority  and responsibility for the performance of the mission, tasks, and work of the maintenance department. Within an organizational  structure,  the  maintenance  officer  (MO), with the aid of subordinate officers, is responsible for management  of  the  maintenance  department  and  is responsible   to   the   commanding   officer   for accomplishment of the department’s mission. The MO uses the guidance in directives from higher authority when he or she directs the maintenance department. Planning,   organizing,   and   controlling   the production effort are management responsibilities of the MO. Along with subordinate officers, the MO directs subordinate divisions to comply with local and higher  authority  maintenance  policies  and  directives.  In an  aviation  organizational  maintenance  activity,  the following  subordinate  officers  assist  the  MO  in management of the department: The assistant maintenance officer (AMO) is the assistant head of the department and assists the MO in the administration of the maintenance department in accordance with the NAMP. The AMO  also  supervises  the  activities  of  staff divisions  (quality  assurance  and  maintenance administration). The maintenance material control officer (MMCO) exercises direct supervision over the production  divisions  (aircraft,  avionics/arma- ment, and line division). Various  divisional  and  branch  officers  manage their respective divisions and branches. The organizational structure of a maintenance department provides a firm line of authority from the MO down to the technician who performs aircraft maintenance. The major segments of the department that report directly to the department head are called divisions. Divisions are subdivided into branches and branches into sections. NOTE: In this manual, the term department is used as a general term and applies to all aircraft maintenance activities that have a department head. ORGANIZATIONAL MAINTENANCE LEVEL Organizational maintenance activities (OMAs) are the  main  users  and  operators  of  naval  aircraft. Therefore,  most  of  the  maintenance  tasks  that  they perform  are  in  support  of  their  own  day-to-day operations.  OMAs  are  composed  of  maintenance managers who manage staff divisions that support the productive  functions  and  production  divisions  that perform the maintenance tasks. Figure 1-1 is an organizational chart of a typical organizational-level maintenance department. The number shown in the various boxes are division and work center codes. Work center codes identify what shop performed what maintenance. The Maintenance Data System uses work center codes in recording and reporting  maintenance  actions.  Typical  work  centers include  maintenance  control  and  quality  assurance. Staff Divisions In  an  OMA  activity,  staff  divisions  provide services and support for the production divisions. They correlate   the   accomplishments   and   progress   of production divisions. Collectively, staff divisions give the MO a consolidated view and current status of the overall  maintenance  picture.  Detailed  functions  and responsibilities of staff divisions are contained in the NAMP.  The  quality  assurance  and  maintenance administration work centers are staff divisions in an OMA. MAINTENANCE  ADMINISTRATION.—The maintenance administration work center provides the following administrative services for the department: Prepares  maintenance-related  correspondence that requires action or special attention by the MO or higher authority Establishes  and  maintains  a  central  main- tenance  reporting  and  record-keeping  system  for administrative  reports  and  correspondence  to include a tickler file to ensure timely submission of recurring reports Implements  directives  that  concern  dis- tribution,  retention,  and  disposition  of  ad- ministrative reports and records Provides  clerical  and  administrative  services  for the department Maintains a master maintenance message board that is annotated with the action that was taken 1-5
