5. How to Locate Repair Parts
a. When NSN or reference number is unknown:
(1) First. Using the table of contents, determine the assembly (functional group) within
which the repair part belongs.
5
(2) Second. Using the repair parts listing, find the functional group to which the repair part
belongs and locate the item by description.
b. When NSN or reference is known:
(1) First. Using the index of NSN's and reference numbers, find the pertinent NSN or
reference number. This index is in ascending NSN cross-referenced to the illustration figure number and item
number.
