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

NSN. However, the complete NSN
should be used when ordering items
by stock number.

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.
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).
