E-6. HOW TO LOCATE REPAIR PARTS.
When National Stock Number or Part is known:
Using the Index of National Stock Numbers and Parts Numbers, find the pertinent National Stock Number
or Part Number. The NSN index is in the National Item Identification Number (NIIN) sequence,
paragraph E-4. The part numbers in the Part Number index are listed in ascending alphanumeric sequence,
paragraph E-4. Both indexes cross-reference you to the illustration figure and item number of the item you
are looking for.
After finding the figure and item number, verify that the item is the one you are looking for, locate the item
number in the repair parts list for the figure.
When National Stock Number or Part Number is NOT known:
Using the table of contents, determine the assembly or subassembly group to which the item belongs. This
is necessary since figures are prepared for assembly groups and subassembly groups, and listings are
divided into the same groups.
Find the figure covering the assembly or subassembly group to which the item belongs.
Identify the item on the figure and note the item number.
Refer to the Repair Parts List for the figure to find the part number for the item number noted on the figure.
Refer to the Part Number Index to find the NSN, if assigned.
