HOW TO LOCATE REPAIR PARTS
When National Stock Number or Part Number is Not Known.
1. First. Using the table of contents, determine the functional group or sub-functional group to which the
item belongs. This is necessary since the figures are prepared for functional groups and sub-
functional groups, and listings are divided into the same groups.
2. Second. Find the item on the figure covering the functional group or sub-functional group to which the
item belongs.
3. Third. Identify the item on the figure and note the item number of the item.
4. Fourth. Refer to the Repair Parts List for the figure to find the line item entry for the item number
noted on the figure.
When National Stock Number or Part Number is Known.
1. First. Using the Index of National Stock Numbers and Part Numbers, find the pertinent National Stock
Number or part number. The NSN index is in the National Item Identification Number (NIIN)
*sequence. The part numbers in the Part Number index are listed in ascending alphanumeric
sequence. Both indexes cross-reference you to the illustration figure and item number of the item you
are looking for.
*The NIIN consists of the last 9 digits of the NSN, as shown above.
