C-5.  Special  Information. a. USABLE ON CODE. The usable on code ap- pears  in  the  lower  left  corner  of  the  Description  col- umn heading. Usable on codes are shown as “UOC . . . . . . . ”  in  the  Description  Column  (Justified  left)  on the  first  line  applicable  item  description/nomenclature. Uncoded  items  are  applicable  to  all  models.  Identifica- tion of the usable on codes used in the RPSTL are: Code Used On Not  Applicable b.  FABRICATION  INSTRUCTIONS.  Bulk  materi- als required to manufacture items are listed in the Bulk Material Functional Group of this RPSTL. Part numbers  for  bulk  materials  are  also  referenced  in  the description  column  of  the  line  item  entry  for  the  item to be manufactured/fabricated. Detailed fabrication in- structions  for  items  source  coded  to  be  manufactured or fabricated are found in the maintenance portion of this  manual. c.  ASSEMBLY  INSTRUCTION.  Detailed  assem- bly instructions for items source coded to be assem- bled  from  component  spare/repair  parts  are  found  in the maintenance portion of this manual. Items that make  up  the  assembly  are  listed  immediately  follow- ing the assembly item entry or reference is made to an applicable figure. e. INDEX NUMBERS.  Items which have the word BULK in the figure column will have an index number shown in the item number column. This index number is  a  cross-reference  between  the  National  Stock  Num- ber/Part  Number  Index  and  the  bulk  material  list  in Section II. C-6. How to Locate Repair Parts. a. When  National  Stock  Number  or  Part  Number  is Not  Known. (1) First. Using the table of contents, determine the assembly group or subassembly group to which the item belongs. This is necessary since figures are prepared  for  assembly  groups  and  subassembly groups, and listings are divided into the same groups. (2) Second. Find the figure covering the assem- bly group or subassembly group to which the item be- longs. (3) Third. Identify the item on the figure and use the Figure and Item Number Index to find the NSN. b. When  National  Stock  Number  or  Part  Number  is Known. (1) First. Using the National Stock Number or Part Number Index, find the pertinent National Stock Number or Part Number. The NSN index is in Na- tional Item ldentification Number (NIIN) sequence (see  4.a(1)).  The  part  numbers  in  the  Part  Number  in- dex are listed in ascending alphanumeric sequence (see 4.b). Both indexes cross-reference you to the il- lustration  figure  and  item  number  of  the  item  you  are looking  for. (2) Second. Turn to the figure and item number, verify that the item is the one you’re looking for, then locate the item number in the repair parts list for the figure. C-7.   Abbreviations.
