The LRCAs are part of an activity’s repairable fixed allowance and are generally stored in a location that hastens timely IMA repair and return to the shelf in RFI condition. The rotatable pool portion of LRCAs is located in an area that promotes efficient supply support of aircraft maintenance; that is, rapid issue to an organizational maintenance activity/ intermediate maintenance activity (OMA/IMA), rather than storage or recordkeeping convenience. Co-location of the rotatable pool with either IMA production control or the IMA is the most desirable arrangement. The supply department prepares a list of repairable items carried in the LRCA storage loca- tions, with specific identification of rotatable pool items. The list is then distributed to all aircraft maintenance activities requiring supply support. The list format includes the NSN, manufacturer’s part number, CAGE code, WUC, family group code, description, and LRCA item number in various sequences adapted to the needs of the maintenance activities. Supply Screening Unit The SSU is responsible for processing all items returned from the IMA. The SSU prepares the retrograde material for shipment to the DOP or the designated support point (DSP) via the advanced traceability and control (ATAC) pro- gram within 2 workdays. When processing field level repairable, refer to OPNAVINST 4790.2, chapter 14. Rapid movement of beyond capability of maintenance (BCM) depot level repairable (DLRs) into the DOP pipeline is required before requisitioning replacements for stock or end use. Where practical, items designated movement priority designator 03 in the Master Repairable Item List (MRIL) are retained awaiting shipment no longer than one-half of a workday. Under fixed allowance procedures, DLRs must be certified BCM and prepared for shipment to a DOP before a replacement can be requisi- tioned for stock or end use (excluding CRIPL items and ZA9 project code). Every section or unit concerned with repairable must make sure BCM DLRs are handled quickly. Unserviceable DLRs retrograded to a HUB, DSP, or DOP are assigned document numbers as follows: . NRFI returns as a result of an issue from wholesale stock or Navy Stock Fund stores account. The retrograde uses the document number that appears in the exchange issue requisi- tion; for example, the customer’s document number. l NRFI returns as a result of an issue from end use. The retrograde is returned citing the 5-11
