l Maintaining adequate accountability of material and equipment on custody. . Maintaining inventory control of autho- rized allowances of material listed in the individual material readiness list (IMRL). . Validating not mission capable supply/ partial mission capable supply (NMCS/PMCS) requisitions daily and maintaining (by aircraft bureau number) current NMCS/PMCS status records. l Performing an inventory of aircraft, with technical assistance, upon receipt or transfer, and making sure inventory log entries are made and inventory shortage listings are prepared and forwarded to maintenance control for inclusion in the aircraft inventory record (AIR). . Maintaining control and records to guarantee turn-in of defective components within established time frames. ORDERING PARTS AND MATERIAL Rapid communication between the material control code (MCC) and the SSC is effected through the use of data transmission equipment. The effective use of communication devices permits maximum coordination between supply and maintenance, thereby improving the overall material management program. Communication equipment may include telephones, radios, teletypewriters, and computers. When material or parts are ordered, material control should take action as follows: l Receive requirements from work centers, support areas, and so forth. l Forward requirements to the SSC using locally approved methods of communication. Make sure the data provided to the SSC is clear and legible and that a document number is assigned. l Enter the date and time that the material was ordered in the material control register to reflect the exact time of submission to the SSC. This time is required for determining accurate NMCS/PMCS start time and conducting follow- up inquiries. l When a repairable component is ordered, make sure the defective component is available for simultaneous exchange. In some instances, it is not feasible or advisable to remove a repairable component until a replacement is in hand. The items in this category are identified in the Consolidated Remain-in-Place List (CRIPL). The respon- sibilities and procedures for establishing, main- taining, and modifying the CRIPL are in OPNAVINST 4420.25. Items identified in the CRIPL are the only authorized exceptions to the one-for-one exchange rule. RECEIPT OR DELIVERY OF PARTS AND MATERIAL Upon receipt of material or parts, material control has the following responsibilities: . Receives the material and DD Form 1348 (or facsimile form) from the SSC material delivery unit. l Signs the DD Form 1348 hardback copy as a receipt (yellow, green, and hardback for repairable). . Enters the date and time the material is delivered to the specified delivery point on the DD Form 1348 pink and hardback copies and in the material control register or request document facsimile. This time is required for determining accurate NMCS stop time. l Distributes received parts and material to the appropriate work center or work area. . Obtains the signature of the work center personnel receiving the material on the DD Form 1348 pink copy and files the copy in the completed requisition file. . Turns in defective repairable CRIPL components within 24 hours. UNSATISFACTORY ISSUES Instances will occur when the supply response section (SRS) delivers material that does not 5-2
