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/P/N index

work packages and the bulk material list in the repair parts list work package.

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.

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.

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.

When P/N Is Known.

First. If you have the P/N and not the NSN, look in the PART NUMBER column of the P/N 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.
