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
