P-437, NAVSUP P-485, or NAVSUP P-545 for the BK2 document format. Weapons Replaceable Assembly (WRA) Turn-in A weapons replaceable assembly (WRA) must be turned-in as a complete unit. If a shop replaceable assembly (SRA) is missing, the activity that turned-in the WRA will be billed for the SRA if no turn-in for the SRA is recorded. The naval aviation depot or other repair facility submits the replacement requisition for the missing SRA. The requisition will have an advice code 5G if the activity who turned-in the WRA can be identified. An advice code 5A will be used when the activity who turned-in the WRA cannot be identified. If the turn-in activity can be identified through any of the accompanying documentation, the repair facility sends a variance report to the NAVICP. The variance report includes the following information: l l l l l National stock number (NSN) of the WRA, turn-in document number of the WRA, NSN and nomenclature of the missing SRA, turn-in document number of the missing SRA (if available), and requisition number for the replacement of the missing SRA. The NAVICP uses the information in the variance report to search the carcass tracking record (CTR) if the missing SRA was turned-in. If a turn-in is recorded in the CTR, the carcass tracking loop and additional billing on the repair facility’s replacement requisition is closed. If no turn-in is recorded, the NAVICP sends a follow up to the activity that turned-in the WRA requesting information on the SRA. If the turn-in activity cannot provide the information, the activity will be billed for the value of the missing SRA. Advanced Traceability and Control (ATAC) The ATAC program has simplified the DLR retrograde process. The ATAC program provides the following efforts: . Provides traceability and accountability l Establishes consolidation and shipping nodes and centralize processing Hubs l l l l Ensures processing of TIR for retrograde material to the NAVICP Reduces carcass tracking follow-ups Reduces delays in transportation and processing Provides database of information for tracking retrograde from receipt in ATAC to delivery to designated repair point (DRP)/designated support point (DSP) Refer to NAVSUPINST 4421.20 for detailed information on the ATAC program. CARCASS TRACKING The carcass tracking program ensures accountability and return of repairable retrograde in the Navy supply system. Repairing a non-RFI depot level repairable (DLR) item is less expensive than buying a new replacement item. In most cases, it is also faster to repair than to buy the items. Since DLR items are expensive and need a long procurement lead time, repair of non-RFI DLRs become the main source of replenishment. Therefore, it is imperative that non-RFI DLRs be returned according to the procedures in NAVSUP-P 545. Delay or erroneous shipment of a DLR retrograde adversely affects material availability and impacts the Navy’s readiness. Definitions Some of the terms specifically used in the carcass tracking program are listed in the following definitions. Knowing these terms will help you learn and understand the scope of the program easier. Freight agent—A commercial activity under contract to the Navy. The freight agent at Nodes is responsible for the DLR receipt and consolidation and forwarding the DLR to the Hub. The agent at the Hub is responsible for processing the DLR receipts and subsequent delivery to DRP/DSP. Additionally, the freight agent maintains the transportation data for information and research. Hub—A Navy-operated facility that provides verification of a drawing/part number to the stock number of the DLR item. The Hub prepares and submits a report of discrepancies for discrepant receipts. The Hub also determines the DRP/DSP of the item and repacks material for shipment. After processing the receipt of a DLR, the Hub submits the transaction item report (TIR) to close the carcass tracking. 4-16
