SECTION I TB 9-2510-251-13 C-7. How to Locate Illustrated Parts. a. When National Stock Number or Part Number is not known. (1) First. Using the table of contents, determine the assembly 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 subassembly group to which the item belongs. (3) Third. Identify the item on the figure and use the part number or NSN shown. b. When National Stock Number or Part Number is known. (1) First. Using the National Stock Number or Part Number, find the pertinent NSN or PN. The NSN index is in National Item Identification Number (NIIN) sequence (see 4b(1)). The part numbers in the PN index are listed in ascending alphanumeric sequence (see 4a). Both indexes cross-reference to the illustration/figure and item number of the item. (2) Second. Turn to the figure and item number, verify the item is the one you’re looking for, then locate the item number in the Repair Parts List for the figure. C-8/(C-9 Blank)
