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
