Systems Command (NAVAIRSYSCOM) to operating and supporting activities in the form of technical manuals, equipment change directives, and engineering data.
Aircraft squadrons, combat ships, station maintenance departments, and other nonindustrial units are provided only the necessary maintenance data in the form of technical manuals and equipment change directives. Industrial-type activities, such as naval aviation depots (NADEPs), are provided for all of the above, plus engineering data (including drawings).
To attain a satisfactory state of readiness, technical manuals are developed, published, and distributed concurrently with aircraft and aircraft systems. Periodic changes and revisions are issued as necessary to ensure that manuals continually reflect equipment configuration and current operational and support concepts and procedures. Technical manuals released under the authority of the Commander, Naval Air Systems Command (NAVAIR) are considered the only authorized source of the information, and the instructions they contain are mandatory. Detailed information on the NAVAIR technical manual program is contained in NAVAIR 00-25-100.
One type of technical manual is the maintenance manual. This type of manual provides instructions for the effective use and support of weapons systems and equipment. The information provided by this manual includes troubleshooting, fault detection, installation, removal, repair, and illustrated parts breakdowns. The major types of manuals are described in the following paragraphs.
Each MIM usually consists of a series of volumes specifically numbered for identification of a given aircraft or weapons system. These manuals provide both general and specific instructions required for maintenance of organizational, intermediate, or depot levels of maintenance on aircraft, weapons systems, equipment, and components.
Component and equipment manuals cover all types of aircraft accessories and related equipment. Some of the most common are accessory, instrument, armament/ordnance, electronics/ avionics, tools, test equipment, and support equipment such as test and shop equipment and ground handling equipment.
Work unit code manuals provide a listing of assigned alphanumeric codes for identification of installed systems or equipment.
These publications provide a basis for planning, scheduling, and complying with scheduled maintenance requirements. The requirements are scheduled with intervals such as calendar time, flight time, operating hours, or number of cycles or events. In instances where conflicts exist between PMS publications and other directives, the PMS publication takes precedence. The publications used within the planned maintenance system (PMS) are discussed below.
Periodic maintenance information cards (PMICs) contain the following information:
l The component removal/replacement schedule and scheduled removal component (SRC) card requirements for items that have an approved mandatory removal/replacement interval
. The record of applicable technical directives, which lists the technical directives that have been incorporated in the appropriate maintenance requirement cards (MRCs) since the last revision
. The maintenance requirements system index, which lists by WUC system and MRC number the requirements to be performed
. The conditional inspection listing, which contains a brief description of the condition and inspection to be performed and a reference to the manual or directive containing the detailed requirements
Maintenance requirement cards (MRCs) are 5- x 8-inch cards that provide step-by-step instructions required for the efficient performance of certain maintenance tasks. Each MRC contains the tasks relating to a particular system, subsystem, area, or component using a logicalContinue Reading
