EXPLANATION OF CROSS-REFERENCE INDEXES WORK PACKAGES FORMAT AND COLUMNS
1.
National Stock Number (NSN) Index Work Package. NSNs 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. This column 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. This 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
UOC. The UOC appears in the lower left corner of the Description Column heading. Usable on codes are shown
as "UOC:" in the Description Column (justified left) on the first line under the applicable item/nomenclature.
Uncoded items are applicable to all models. (Note: UOCs are not used in this RPSTL.)
HOW TO LOCATE REPAIR PARTS
When NSNs or Part Numbers Are Not Known.
1.
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 sub functional 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 for which
you are looking.
3.
When Part Number Is Known.
First. If you have the part number and not the NSN, look in the PART NUMBER column of the
part number index work package. Identify the Figure and item number.
Second. Look up the item on the Figure in the applicable repair parts list work package.
