materials are financed by procurement appropriations. These  are  the  Aircraft  Procurement  Navy  (APN), Weapons  Procurement  Navy  (WPN),  or  Other Procurement  Navy  (OPN)  appropriations.  Some examples of items carried in APA are aircraft engines, radar systems, computers, and soon. The contractor supported items are identified by a 0_ Cog. The contractor provides the support during the interim pied as agreed upon by the vendor and the Hardware Systems Command (HSC). The contractor support terminates at the Material Support Date (MSD). An MSD is the agreed upon date when the ICP will accept  the  responsibility  for  the  support  of  the  items. Upon  acceptance  of  responsibility,  the  items  are assigned with the appropriate cognizance symbol for the ICP. Refer to Appendix 17, Part C of NAVSUP P-437  for  a  list  of  cognizance  symbols  and  their cognizant ICPs. The  End-Use  DLRs  are  held  in  Stores  Account 55000 for shorn activities. This also applies to afloat units using the Shipboard Uniform Automated Data Processing   System-Real   lime   (SUADPS-RT)   with Uniform System Identification (USID) codes C or M. The USID code C applies to ships with designations of CV, CVN, LHA, LPD, and LHD. The USID code M applies   to   Marine   Aviation   Logistics   Squadrons (MALS). Under this concept, the supporting activity (not   the   customer)   is   responsible   for   the   issue, replenishment, and financial accounting of end-use inventories. Ashore, end-use DLRs are carried in the W or L purpose. Afloat, a majority of these items are carried  under  allowance-type  (AT)  code  2.  ‘he  aviation activities  buy  end-use  DLRs  with  Operations  and Maintenance  funds  apportioned  to  them  by  their respective type commanders. The supply officer also uses  the  Operations  and  Maintenance  fund  to  maintain the inventory of end-use DLRs. Condition Codes To manage repairable components properly, you should distinguish the condition of items in stock. The manager must know if an item is in RFI condition, requiring   repair,   or   being   repaired.   The   supply condition  code  is  assigned  to  classify  the  materials  in terms of their readiness for issue and use. As material moves  through  the  repair  cycle,  its  condition  code changes. The most current condition code is used to record the status of the material. A complete listing of supply  condition  codes  is  listed  in  appendix  A2  of MILSTRIP/MILSTRAP,  NAVSUP  P-437,  and appendix 9 of Afloat  Supply  Procedures,  NAVSUP P-485. Local Repair Cycle Asset (LRCA) The  LRCA  storage  unit  is  under  the  Aviation Support Division/Supply Support Center (ASD/SSC) of a supply department. This unit is responsible for receiving,  storing,  issuing,  and  accounting  of  repairable assets controlled by ASD/SSC. The LRCA is part of the activity’s fixed allowance and stored close to the intermediate  maintenance  activity  (IMA).  To  prevent submitting a requisition to the supply system every time a  replacement  serviceable  unit  is  needed,  NAVICP-Phil provides  a  fixed  allowance  to  the  supporting  activity. When an NRFI unit is removed from an aircraft or equipment,  an  RFI  replacement  is  issued  from  the LRCA storage unit. The NRFI unit is inducted into the IMA for repair. When the item is repaired locally, it is returned to the stock storage as an RFI asset. When the item cannot be repaired locally, or when the item is an AVDLR,  it  is  then  forwarded  to  the  designated  repair point/designated support point (DRP/DSP) for repair and an RFI replacement unit is requisitioned from the supply system. A fixed allowance is established based upon an estimate  of  the  activity’s  usage  considering  such  factors as failure rates, operating hours, and the I-level repair turn-around  time  (TAT). The important factor in determining the allowance quantity of a repairable item is the TAT. The TAT is the length of time from the removal of the NRFI component to its restoration to serviceable condition and returned to the shelf. The objective of the maintenance activity is to keep this TAT as short as possible. The total repair process can be thought of as a circular  system  wherein  the  unserviceable  unit  enters the repair program in F condition and is repaired and returned  to  stock  in  A  condition.  This  process  is referred to as depot repair cycle. Master Repairable Item List (MRIL) The  MRIL  is  the  official  designated  source  for determining  the  proper  disposition  of  NRFI  repairable. The MRIL is available in Compact Disk Read-Only Memory  (CD-ROM)  and  in  mechanized  format. The MRIL in CD-ROM is the primary source of information  for  nonmechanized  activities.  This  format is updated in its entirety, published, and distributed monthly. The CD-ROM format is in two parts. 4-3
