EXPLANATION OF CROSS-REFERENCE INDEXES WORK PACKAGES FORMAT AND COLUMNS
1. National Stock Number (NSN) Index Work Package. NSN's in this index are listed in National Item Identification
Number (NIIN) sequence.
STOCK NUMBER Column. This column lists the NSN in 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.
For example, if the NSN is 5385-01-574-1476, the NIIN is 01-574-1476.
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. Part numbers 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 part number assigned to the item.
FIG. Column. This column lists the number of the figure where the item is identified/located in the repair parts list
and special tools list work packages.
ITEM Column. The item number is the number assigned to the item as it appears in the figure referenced in the
adjacent figure number column.
SPECIAL INFORMATION
Fabrication Instructions. Bulk materials required to manufacture items are listed in the bulk material functional
group of this RPSTL. Part numbers for bulk material 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 Illustrated List of Manufactured Items.
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/Part Number (P/N) Index work packages
and the bulk material list in the repair parts list work package.
HOW TO LOCATE REPAIR PARTS
1. When NSNs or Part Numbers Are Not Known.
First. Using the table of contents, determine the assembly group to which the item belongs. This is necessary since
figures are prepared for assembly groups and subassembly groups, and lists are divided into the same groups.
Second. Find the figure covering the functional group or the subfunctional group to which the item belongs.
Third. Identify the item on the figure and note the number(s).
Fourth. Look in the repair parts list work packages for the figure and item numbers. The NSNs and part numbers
are on the same line as the associated item numbers.
2. When NSN Is Known.
First. If you have the NSN, look in the STOCK NUMBER column of the NSN index work package. The NSN is
arranged in NIIN sequence. Note the figure and item number next to the NSN.
Second. Turn to the figure and locate the item number. Verify that the item is the one you are looking for.
