or  ordering  repair  parts.  The  appropriate  shop supervisor is responsible for ensuring that they are prepared  according  to  COMCBPAC/COMCB- LANTINST  4400.3  series. Repair Parts Available from Stock After the shop supervisor or higher authority authenticates the request, the cost control clerk submits  the  form  to  the  repair  parts  storeroom with the ERO, After receiving the required part, the  receiver  signs  NAVSUP  Form  1250-1  (fig. 2-1 5) in data block 31. The repair parts person then  enters  the  NSN  quantity  and  price  on  the ERO   worksheet   and   verifies   the   issue   by initials. Repair Parts Not in Stock (NIS), Not Carried (NC), or Procured from Salvage or Local Manufacture If the repair part requested is NIS or NC, the storeroom  storekeeper  marks  an  “X”  in  the appropriate  box  in  data  block  12  and  verifies  data entries. The  request  for  an  NIS/NC  repair  part  will be attached to the ERO and returned to the cost control   office   for   review   by   the   maintenance supervisor  and  assignment  of  the  urgency-of-need designator.   The   ERO,   with   NAVSUP   Form 1250-1 or 1250-2 attached, is then passed to the cost  control  clerk,  who  records  the  information in  the  DTO  log  and  DTO  Summary  Sheet.  The cost  control  clerk  pulls  the  yellow  copy  of  the ERO  and  files  it  with  the  DTO  Parts  Summary Sheet.   Nonoperational   ready   supply   (NORS)/ anticipated   nonoperational   ready   supply (ANORS)  entries  in  the  DTO  log  are  annotated in red ink. Requests for repair parts with an urgency-of- need designator “B” in data block 3 require the approval  signature  of  the  ALFA  FOUR  or designated assistant in data block 30. All urgency- of-need   designator   “A”   requests   require   the approval  signature  of  the  ALFA  SIX. The  supply  department  orders  the  NIS/NC repair  part  and  returns  the  yellow  copy  of NAVSUP  Form  1250-1  or  1250-2  (fig.  2-16) within 72 hours after assigning the Julian date and serial  number  in  data  block  B  (fig.  2-15).  The Julian date and serial number, referred to as the requisition number, are entered in the DTO log and will always be used for reference whenever a request is made for the requisition status of an outstanding  order. When any NIS/NC repair part is received, the item  is  given  to  the  DTO  clerk.  The  DTO  clerk notates the part received on the DTO log and the appropriate  DTO  Summary  Sheet.  The  yellow copy of the NAVSUP 1250-1 or 1250-2 (figs. 2-15 and 2-16) is taken from the file and attached to the  part,  which  is  then  stored  in  the  DTO  bin according to the PM group of the equipment for which it was ordered. Any DTO part received for a  deadline  piece  of  equipment  must  be  brought to  the  attention  of  the  maintenance  supervisor  for disposition. Repair  parts  from  salvage  or  local  manu- facture  (fabrication  within  the  unit)  may  not involve procurement or issue action through the repair parts storeroom but must be documented for  purposes  of  cost  control  and  historical demand. NON-NSN   Requisition,   NAVSUP   Form 1250-2 (fig. 2-16), is processed in the same manner as  NAVSUP  Form  1250-1  (fig.  2-15). Job Control Number (JCN) The  job  control  number  consists  of  fourteen alphanumeric characters. The first six characters are the service designator (R, V, or N) and unit identification   code   (UIC).   The   next   four characters  are  the  work  center  (WC)  code  (for example,  “AAOO”)  as  defined  in  COMCBPAC/ COMCBLANTINST 4400.3 series. The last four- character group is a locally assigned job sequence number  (JSN). WRONG  PARTS! Each  year  millions  of  dollars  are  wasted  by ordering  wrong  parts.  As  a  maintenance supervisor, you are responsible for ensuring that the  Construction  Mechanics  assigned  to  the technical  library  are  researching  and  ordering repair  parts  accurately.  Strict  adherence  to  proper supply  procedures  and  a  strong  working relationship with your supply department will help prevent waste, save the government thousands of dollars, and curb unnecessary CESE downtime. REPAIR  PARTS  TURN-IN In the event, for one reason or another, that “the  wrong  parts”  arrive  at  your  site,  do  NOT ignore  the  problem.  Such  actions  as  hiding  or burying  them,  giving  them  away,  or  destroying them  are  all  illegal,  and  severe  disciplinary  action can be taken against you.
