How to Locate Repair Parts.
a.
When National Stock Number or Part Number is Not Known.
(1) First.
Using the table of contents, determine the assembly
group 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.
(2) Second.
Find the figure covering the assembly group or sub-
assembly group to which the item belongs.
(3) T h i r d.
Identify the item on the figure and note the item
number.
(4) Fourth.
Refer to the Repair Parts List for the figure to find
the part number for the item number noted on the figure.
(5) Fifth.
Refer to the Part Number Index to find the NSN, if
assigned.
b.
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 National Item Identification
Number (NIIN) sequence (see 4. 1(1)). The part numbers in
the Part Number index are listed in ascending alphanumeric
sequence (see 4. b).
Both indexes cross-reference you to the
illustration figure and item number of the item you are looking
for.
(2) Second.
After finding the figure and item number, verify that
the item is the one you’re looking for, then locate the item
number in the repair parts list for the figure.
