5. How to Locate Repair Parts.
a. When National Stock Number or Part
Number is Unknown:
(1) First. Using the table of contents, deter-
mine the functional group within which the repair
part belongs. This is necessary since illustrations
are prepared for functional groups, and listings are
divided into the same groups.
(2) Second. Find the illustration covering the
functional group to which the repair part belongs.
(3) Third. Identify the repair part on the il-
lustration and note the illustration figure number
and item number of the repair part.
(4) Fourth. Using the Repair Parts Listing,
find the figure and item number noted on the il-
lustration.
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 Na-
tional stock number or part number. This index is
in NIIN sequence followed by a list of part
numbers in
alphanumeric
sequence,
cross-
referenced to the illustration figure number and
item number.
(2) Second. After finding the figure and item
number, locate the figure and item number in the
repair parts list.
