for recurring issues of specific items. The supply response section (SRS) of ASD manages the PEB. MCC should review requests for consumable items against the PEB listing provided by the supporting supply activity. Requisitioning In the process of ordering the items needed to support maintenance, MCC should perform the following: l Receive requests from work centers or areas. l Log requirements in the material control register or log book. . Forward requirements to ASD by using requisition forms or by electronic means. Ensure the data on requisitions are correct. Refer to chapter 4 of this manual for requisitioning procedures. For activities using NALCOMIS, submit requisi- tions by using Conversation codes N601 or N602. Use Conversation code N601 for direct support (MAF- related) material requirements. Use N602 for indirect support (not related to MAF) material requirements. . Enter the date and time in the register or log to reflect the exact time of submission to ASD. This time is required for determining the accurate timing for conducting follow-up inquiries. When ordering a repairable component, the defective component must be available for simultaneous exchange upon delivery of the item. When ASD personnel pick up the defective component, you should obtain a signature as proof of turn-in. Field-level repairable with assigned SM&R code PAOOO must be processed through the Aeronautical Material Screening Unit (AMSU) for disposition. The AMSU is part of the maintenance department. In some instances, it is not feasible or advisable to remove repairable components until a replacement is in hand. The Consolidated Remain-In-Place List (CRIPL) identifies those items included in this group. The items listed in the CRIPL are the only authorized exceptions to the one-for-one exchange rule. OPNAVINST 4440.25 (series) describes the responsibilities and procedures for establishing, maintaining, and modifying the CRIPL. Establishment of phase maintenance kits is optional as directed by the aircraft controlling custodian (ACC) or type commander (TYCOM). When the program is implemented, the following procedures apply. l Maintenance and material control officers jointly determine phase maintenance kit requirements. They do this by using the Maintenance Requirements Cards (MRC) and other maintenance information. . Material control prepares and submits a listing of items included in the phase kits. The listing must have the part number and quantity of each item in the kit. Also, the listing must include the support period of the kit; for example, 30-day maintenance period. . Material control must tell ASD if the kit requires replenishment. MCC also must inform ASD about any changes in part numbers or quantity requirements in the kit. l The phase maintenance kits may be pre- expended or charged to the user upon issue. This is based upon the total parts inventory cost in each kit. l Mandatory turn-in repairable components are not authorized in phase maintenance kits. These are the depot-level and field-level repairable items. Requisition Monitoring Monitoring requisitions is necessary to keep the outstanding file current. You should monitor requisitions from the date of submission until receipt of material. There are options for modifiers, follow-ups, and cancellations, as well as receipt of status. A NALCOMIS activity uses Conversation code N668 to review past and current status of a specific requisition. The supporting ASD provides a listing of all outstanding NMCS, PMCS, and ANMCS requisitions daily. This listing contains the document number, NSN, unit of issue, quantity, project code, and priority. Also, it may contain the nomenclature, aircraft bureau number, requisition status, JCN, and WUC. Listings may have additional information as set by existing procedures. You must review this listing with maintenance control and make changes as necessary. To effectively monitor the outstanding requisitions, you must be familiar with set procedures. This includes procedures for requisition modifiers, follow-up, and cancellation. Chapter 4 of this manual provides basic information of the procedures for requisition monitoring. Material Obligation Validation The purpose of the material obligation validation (MOV) request is to compare records and make sure that a requirement still exists. Supply activity forwards the 8-4
