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
