maintenance officer or supervisor can carry out their duties more effectively and efficiently. Set up the material control VIDS according to OPNAVINST 4790.2 (series). After receiving a material request from a work center, transmit the demand to the supporting supply activity. Use the requisition priority and project code assigned by production control. Advise maintenance or production control and the work center of the document number assigned. Place a copy of the facsimile transceiver form, register, or other form on the VIDS board. You may use color tabs on the request form to indicate the priority or project code used. NOTE: Activities using the Naval Aviation Logistics Command Management Information System (NALCOMIS) should refer to the user’s manual. Some activities that use NALCOMIS do not use VIDS to maintain files. Hardware VIDS display boards consist of enlarged cardex-type pockets for the visual display of weapons systems or component status. Each pocket overlaps the one below it, with an approximately 3/8-inch strip visible at the bottom pocket. VIDS boards are available in 100, 50, and 25 pockets. Material Requisition Register MCC use the Material Requisition Register (OPNAV 4790/11) to transmit demands to ASD when other means is not available. MCC uses this form to display AWP status. Data sequence is compatible with key entry and the MILSTRIP. Software Items used for the operation of the VIDS may be obtained from the supply system or commercial vendors. These items include signal tabs, file containers, replacement pockets, and three-ring binders. AIRCRAFT INVENTORY RECORDS Activities with assigned aircraft or that maintain aircraft must be familiar with the aircraft inventory record (AIR). The purpose of the AIR is to provide a continuous chain of accountability for specific equipment and material. The equipment or material may be installed on or designated for use on any aircraft of a specified type/model/series. The following text lists the items that make up the AIR. Refer to OPNAVINST 4790.2 (series) for detailed description of each part. . Binder (OPNAV 4790/109). . Title Page and Sectional Breakdown Diagram (OPNAV 4790/110). l Equipment List (OPNAV 4790/111). . Shortages (OPNAV 4790/112). . Certification and Record of Transfer (OPNAV 4790/104) Master Aircraft Inventory Record The Commander, Naval Air Systems Command (NAVAIR) maintains the Master Aircraft Inventory Record (MAIR). The MAIR identifies those items of installed and loose equipment that require a periodic inventory. A MAIR shall be maintained as the standard for each type/model/series aircraft. The MAIR serves as a checklist for items requiring an inventory. Also, it provides reasons/authority for any shortages that exist and documents certificates of accountability. Equipment Accountability In addition to the accountability of AIR items, an accounting of equipment will be done prior to aircraft transfer. These are equipments listed in or comprising subsystems of the applicable mission essential subsystem matrix (MESM). A number of MESM items are identified at the subsystem level rather than by exact equipment designation. Therefore, you cannot use the MESM totally as a specific equipment checklist as you can the AIR. The accounting of most MESM items is by system operation checks and maintaining a VIDS/MAF file vice an AIR-type accountability. When transferring aircraft equipment accountability, those missing MESM-related items will be identified in the AIR as shortages, even though that specific equipment is not listed. Aircraft are transferred and accepted only after completion of equipment/item inventory and notation on the forms of the AIR. In most instances of aircraft transfer, the inventory is accomplished based on the selected equipment and material listed in the AIR and systems identified in the MESM. The following paragraphs provide a list governing the selection of items to be included in the AIR. These items may be government-furnished equipment (GFE) or contractor-furnished equipment (CFE). 8-16
