1. National Stock Number (NSN) Index Work Package.
STOCK NUMBER Column. This column lists the NSN in National item identification number (NIIN)
sequence. The NIIN consists of the last nine digits of the NSN.
When using this column to locate an
item, ignore the first four digits of the
NSN. However the complete NSN
should be used when ordering items by stock number.
FIG. Column. This column lists the number of the figure where the item is identified/located. The figures
are in numerical order in the repair parts list and special tools list work packages.
ITEM Column. The item number identifies the item associated with the figure listed in the adjacent FIG.
column. This item is also identified by the NSN listed on the same line.
2. Part Number (P/N) Index Work Package. P/Ns in this index are listed in ascending alphanumeric
sequence (vertical arrangement of letter and number combinations which places the first letter or digit
of each group in order A through Z, followed by the numbers 0 through 9 and each following letter or
digit in like order).
PART NUMBER Column. Indicates the P/N assigned to the item.
FIG. Column. This column lists the number of the figure where the item is identified/located in the repair

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 instructions
for items source coded to be manufactured or fabricated are found in Appendix (x) of this manual.
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 NSN / P/N index work
packages and the bulk material list in the repair parts list work package.
