Some of the functions of an aircraft maintenance department are as follows: Periodic  maintenance  and  routine  inspection  and servicing of aircraft, associated SE, and aeronautical material and components. Maintenance and inspection include   the   necessary   disassembly,   cleaning, examination, repair, modification, test, inspection, assembly, and preservation. Special work (when required) to comply with TDs or local instructions. On the other hand, a staff relationship (normally shown by a solid horizontal line feeding into the main arteries of the organizational chart) exists between an advisory  staff  supervisor  and  a  production  line supervisor. The sole concern of staff personnel is to service and support the production effort. Management Correction  of  aircraft  and  equipment discrepancies. Assurance of high quality in all work. Maintenance of required records and technical publications. Maintenance and custody of tools and other equipment provided the activity for its own use. Management exercises the authority and takes the responsibility for the performance of the mission, tasks, and work of the maintenance department. The organizational structure lets the aircraft maintenance officer (AMO) (with the aid of subordinate officers) manage the maintenance department. The AMO is responsible  to  the  commanding  officer  for  the accomplishment of the department’s mission. The AMO directs the maintenance department according to directives from higher authority. Training of assigned personnel. Conducting  maintenance  and  ground-handling safety  programs. Submission of reports for statistical, analytical, and historical purposes. The  depth  and  complexity  of  specific  functions vary with the number and type of aircraft involved and the  assigned  maintenance  level.  This  chapter  covers the aircraft maintenance organizations for the 0- and I-level maintenance activities. You will probably be assigned to an activity that performs only 0- or I-level maintenance. The   functional   management   responsibilities assigned  to  the  AMO  are  planning,  control,  and production. Also, the AMO estimates and programs facilities,  equipment,  manpower,  and  training requirements.  With  subordinate  maintenance department officers, the AMO provides direction and guidance  to  subordinate  divisions.  The  subordinate divisions  implement  and  comply  with  all  local-  and higher-authority  maintenance  policies  and  technical directives.  Normally,  the  following  subordinate officers assist the AMO in the management of the maintenance  department: Organizational Structure Relationships Assistant  aircraft  maintenance  officer.  This officer ensures that the staff divisions conform to established  policies  involving  quality  assurance  and supervises maintenance administration and department training. The  organizational  structure  of  aircraft  main- tenance activities uses the principles and concepts of  modern  management.  This  structure  incorporates the  basic  aspects  of  organizing-pinpointing responsibilities, span of control, alignment of functions, division of work, uniformity of assignments, and delegation  of  authority  commensurate  with  the assignment of responsibility. Maintenance  material  control  officer.  This officer is directly responsible to the AMO for the overall productive effort and material support of the department, Aircraft  maintenance  division  and  branch officers. These officers organize and manage their respective divisions and branches. A line relationship (normally shown by a solid Specific  responsibilities  of  these  officers  are vertical  line  on  an  organizational  chart)  is  a outlined in OPNAVINST 4790.2. The organization of relationship  that  exists  between  a  superior  and the maintenance department provides firm lines of subordinate within both staff and line segments of the authority from the AMO to the personnel who do the organization. This relationship involves the direct work for which the department is responsible. Major supervisory  functions  of  assigning  work  to segments,  called  divisions,  of  the  department  report subordinates and appraisal of performance. directly to the department head.
