7-17 Priority Designator The priority designator (PD) is a two-digit number (01,  the  highest,  to  15,  the  lowest).  The  PD  is determined by using the table of priority designators (fig. 7-14). The table is easy to use. For example, if your activity is assigned an F/AD of II and your requirement is of a routine nature, the priority to be assigned would be 12. In addition to providing standardized criteria for assigning  priorities,  UMMIPS  provides  acceptable maximum processing times for use by supply activities in furnishing material. NAVSUP P-485 contains the processing time standards and additional codes used in MILSTRIP and UMMIPS. CASUALTY REPORTING (CASREP) The  casualty  report  (CASREP)  is  designed  to support the Chief of Naval Operations (CNO) and fleet commanders in the management of assigned forces. The effective use and support of Navy forces requires an up- to-date, accurate operational status for each unit. An important   part   of   operational   status   is   casualty information. The CASREP system contains four types of reports: initial, update, correct, and cancel. These reports are described in general in the following paragraphs. CASREPs are not a substitute for, but are in addition to and   complement,   3-M   data.   For   more   complete information  on  the  preparation  and  submission  of CASREPs, see Operational Reports, NWP 10-1-10. Initial Casualty Report (INITIAL) An INITIAL CASREP identifies the status of the casualty and any parts or assistance needed. Operational and staff authorities use this information to set priorities for the use of resources. Update Casualty Report (UPDATE) A  unit  uses  an  UPDATE  CASREP  to  submit changes to previously submitted information. Correction Casualty Report (CORRECT) A  unit  submits  a  CORRECT  CASREP  when equipment that has been the subject of casualty reporting is repaired and is back in operational condition. Cancellation Casualty Report (CANCEL) A   unit   submits   a   CANCEL   CASREP   when equipment that has been the subject of casualty reporting is scheduled to be repaired during an overhaul or some other scheduled availability. Outstanding casualties that will not be repaired during such availability will not be canceled  and  will  be  subject  to  normal  follow-up casualty reporting procedures as specified. MANDATORY TURN-IN REPAIRABLES (MTR) You will, no doubt, encounter the terms mandatory turn-ins and repairables in the process of obtaining replacement parts from supply. Therefore, you need to understand your responsibilities in regard to mandatory turn-in repairable items (MTR). When any of your equipment fails, your primary concern is to locate the trouble, correct it, and get the equipment back on the line. In most instances you first trace the trouble to a defective part and then prepare a NAVSUP   1250-1   (or   DD   1348)   to   obtain   the replacement part from the supply storeroom. Next you install the replacement part and throw away the defective part. However, when the defective part is expensive and repairable, it becomes a part of the repairables program. A  large  number  of  parts  can  be  economically repaired when they fail. This results in savings of dollars and time. Repairing an item is quicker and cheaper than contracting for and buying a new one—provided the old item is promptly returned in repairable condition. For the program to work as intended, you and others have certain responsibilities. At the time you submit your request for a mandatory turn-in item, supply will tell    you    to    return    the    defective    item.    Your responsibilities begin at this point. You must remove the defective part and give it adequate protection to prevent further damage before turning it in to supply. The most effective way to protect the defective part is to place it in the   same   container   in   which   you   received   the replacement part. The defective part or equipment must be accompanied with a copy of the OPNAV 4790/2K, Work Request form describing the failure of the part or equipment. Your protection of the part will help the designated overhaul point (DOP) diagnose and repair the defective component and return the part to service more quickly. Do not cannibalize components you might use sometime in the future.
