functional group to which the repair part belongs.
(3) Third. Identify the repair part on the
illustration and note the illustration figure and item
number of the repair part.

the figure and item number noted on the illustration.
b. When National Stock Number or Part Number is

Numbers and Part Numbers, find the pertinent National
stock number or part number. This index is in ascending
NIIN sequence followed by a list of part numbers in
