beyond the repair capability of the organizational (O-level) or intermediate (I-level) maintenance levels. The DLRs in Not Ready For Issue (NRFI) condition must be shipped to the dept level maintenance activity for repair or disposition. The DLRs are identified by MCCs E, G, H, Q, or X (with the exception of cognizance 6RX). Advanced technology has made the weapons systems more sophisticated. The equipment, components, and related parts necessary to sustain the weapons systems also have become more complex and specialized. The weapons replaceable assembly (WRA) is the generic term that includes all replaceable packages of an avionic equipment or system as installed in the aircraft weapons system. The WRA does not include cable assemblies, mounts, fuse boxes, or circuit breakers. The WRA is composed entirely of shop replaceable assemblies (SRAs). The shop replaceable assembly (SRA) is a generic term that includes all the packages in the WRA. The SRAs include the chassis and wiring as a unit. NOTE: An SRA may be made of other SRAs. Several shop replaceable assemblies (SRAs) make up a weapons replaceable assembly (WRA). When a component fails and it is diagnosed that the cause is in an SRA, the entire SRA module containing the defective part is removed and replaced. Repairable items are expensive and normally require a long lead time in procurement. However, if the defective SRA components are repaired and returned to the supply system, the fleet can maintain its readiness. Stock records at all supply levels must reflect total quantities of all available repairable components. These quantities are reported to the NAVICPs. The report will enable the NAVICPs to have an accurate count of assets to budget for procurement and distribution. The NAVICPs also use the report to determine proper repair workload scheduling to maintain ready for issue (RR) stock levels, The item manager must keep track of both RFI and not ready for issue (NRFI) material to maintain the required quantity. The NAVICP uses this information to decide whether to buy additional quantities or repair NRFI assets to fill the requirements. Categories of Repairable Initially, an item is designated as repairable or consumable during the development of the maintenance plan by the Hardware Systems Command and implemented into the coding process during the provisioning process. This plan includes information necessary to establish the source maintenance and recoverability (SM&R) code. The maintenance plan also designates the lowest maintenance level that is authorized to perform a specific task on an item. The different maintenance levels are the organizational, intermediate, and depot level. The SM&R code reveals the maintenance level authorized to perform the following work: l l l Remove and replace the item Repair the item Condemn the item if it cannot be repaired After the repair level for an item has been designated, the item is assigned a material control code (MCC) by the item manager. The MCC is a single-letter code used for identification of repairable items, to segregate items into more manageable groups, or to relate to field activities special reporting and/or control requirements. Ownership Aviation Held Level Repairable (AVFLRs) may be carried in purpose codes W or L as authorized stock under an activity’s fixed allowance. The AVFLRs that are excess to the authorized stock levels maybe carried under purpose code A.    Afloat, AVFLRs are carried under stores account 51000 pending issue to customers. In the DLR program, ownership relates to the account under which the repairable material inventories are held. These accounts include the Defense Business Operations Fund (DBOF), Appropriation Purchase Account (APA), contractor supported, and end-use ashore/afloat. The DBOF (formerly Navy Stock Fund [NSF]) is a revolving fund with two major assets, cash and material. The DBOF cycles cash into material inventory by having the components repaired at depots, or by buying from vendors or other stores accounts. When material is received, it is placed on the shelf where it is held in Navy stock account 51000 pending requisitioning by a customer. When the material is issued to the customer, the DBOF is reimbursed by the customer’s operating funds. The DBOF recycles the cash into inventory through repair or purchases and the cycle is then repeated. The Appropriation Purchase Account (APA) material is held in Stores Amount 52000. The APA 4-2
