Part 1 of the CD-ROM MRIL is a list of all DLRs in national item identification number (NIIN) sequence. The information includes associated data pertinent to each item. Some of the data are the Cog, MCC, movement priority designator (MPD), shipping code, and special notes where applicable. The shipping code may be a six-position code beginning with an N, a C, or a W. The N represents a Navy activity with the remaining five digits being the unit identification code (UIC). The C represents a commercial repair facility and the W represents an other service repair facility. The digits following the C or W are not UICs. If the MRIL lists more than one shipping code, ship the item to the closest address from your activity. Shipping codes may also be a WW, XX, YY, or ZZ. Only one shipping code is assigned to an item in the MRIL. his code will either be an alpha alpha or six-digit UIC shipping code but not both. The WW and YY shipping code indicates that the item must be sent to a Defense Reutilization and Marketing Office (DRMO). ‘he XX shipping code indicates that the item is shipped to the closest fleet and industrial supply center (FISC). The ZZ shipping code indicates that disposition and shipping instructions must be requested from the ICP. Part 2 of the CD-ROM MRIL is a list of shipping addresses relative to the shipping code in part 1. This part also includes the supplementary address information wherever applicable. The mechanized MRIL is used by activities having a computer system. The information in the mechanized MRIL is the same as in the CD-ROM format. The mechanized MRIL is established and maintained on three computer disk files from MRIL computer tapes. The MRIL computer tapes are provided monthly by the Fleet Material Support Office (FMSO) to mechanized activities. One of the files is equivalent to the part 1 of the CD-ROM format. The other two files are identical shipping address files except one is in shipping code sequence and the other is in activity sequence code (ASC) order. The ASC is a four-position numeric code. The ASC is developed to permit mechanized processing by computing the difference (value) between the processing activity’s ASC and the listed DRP/DSP ASCs. The lowest value is the closest DRP/DSP whenever there is more that one DRP/DSP to which an item can be shipped. The MRIL must be used in conjunction with other publications. Afloat units should use additional guidance outlined in Afloat Supply Procedures, NAVSUP P-485, and Supply Afloat Packaging Procedures, NAVSUP P-484. Ashore activities should use additional guidance outlined in the MILSTRIP/ MILSTRAP, NAVSUP P-437, and Material Turned in to Store (MTIS) Manual, NAVSUP Instruction 4440.157. The area of the MRIL that is subject to change is the material priority designator (MPD). The item manager (IM) has the option to lower or raise the MPD. The IM raises the shipment priority of the retrograde to the DRP/DSP to expedite repair. The IM may lower the shipment priority if the inventory quantity of the item is sufficient to support future requirements. Advanced Traceability and Control (ATAC) The new procedures for moving NRFI DLRs are provided by ATAC. The ATAC directs shipment of NRFI DLRs to a specific Hub activity within the geographical zones on the east or west coast. It also directs shipments to Transportation Nodes such as Fleet and Industrial Supply Center (FISC) Yokosuka or NAS Sigonella. The Nodes consolidate the shipments of NRFI DLRs and forward the consolidated freight to the closest Hub for processing. The Hub performs full technical screening, packing and preservation, and transaction reporting. The Hub transships the NRFI DLRs to the DRP/DSP according to the MRIL. The two geographic Hubs are FISC Norfolk and FISC San Diego. Some programs are excluded from the ATAC Hub concept. Some of the programs that are excluded are the repair and return, ship’s express, and classified items. Refer to NAVSUP P-545 for a complete list of programs that are excluded from the ATAC Hub concept. FIELD LEVEL REPAIRABLE (FLRs) As described in the previous paragraphs, aviation FLRs are identified by cognizance symbol 1RD. End-use requirements for FLRs are filled from the activity’s fixed allowance. If the required FLR is not available for issue, the NRFI component is inducted for expeditious repair (EXREP). If the EXREP is unable to satisfy the requirement, retail activities may issue from purpose code A assets. Wholesale activities refer their requisitions to NAVICP-Phil. Upon issue of an FLR, the financial transactions will not be recorded when the NRFI turn-in was repaired by the maintenance activity. If the maintenance activity was unable to repair the NRFI turn-in, the expenditure will be recorded at the standard 4-4
