EXPLANATION OF COLUMNS IN THE REPAIR PARTS LIST AND SPECIAL TOOLS LIST WORK PACKAGES
PART NUMBER (Column (5)). Indicates the primary number used by the manufacturer (individual, company, firm,
corporation, or Government activity), which controls the design and characteristics of the item by means of its engineer-
ing drawings, specifications, standards, and inspection requirements to identify an item or range of items.
When you use an NSN to requisition an item, the item you receive may have a different P/N from
the number listed.
DESCRIPTION AND USABLE ON CODE (UOC) (Column (6)).
This column includes the following information:
The federal item name, and when required, a minimum description to identify the item.
P/Ns of bulk materials are referenced in this column in the line entry to be manufactured or fabricated.
Hardness Critical Item (HCI). A support item that provides the equipment with special protection from electro-
magnetic pulse (EMP) damage during a nuclear attack.
The statement END OF FIGURE appears just below the last item description in column (6) for a given figure
in both the repair parts list and special tools list work packages.
QUANTITY (QTY) (Column (7)). The QTY (quantity per figure) column indicates the quantity of the item used in the
breakout shown on the illustration/figure, which is prepared for a functional group, subfunctional group, or an assem-
bly. A "V" appearing in this column instead of a quantity indicates that the quantity is variable and quantity may change
from application to application.
EXPLANATION OF CROSS-REFERENCE INDEXES WORK PACKAGES FORMAT AND COLUMNS
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 (e.g., 5385-01-574-1476) item, ignore
the first four digits of NIIN 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 nu-
merical 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 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 reference in the adja-
cent figure number column.
HOW TO LOCATE REPAIR PARTS
When NSNs or P/Ns 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.
Find the figure covering the functional group or the subfunctional group to which the item belongs.
