HOW TO LOCATE REPAIR PARTS
1. When NSNs or Part Numbers Are Not Known.
First. Using the Table of Contents, determine the assembly group to which the Item belongs. This is necessary
since igures are prepared for assembly groups and subassembly groups, and lists are divided into the same
groups.
Second. Find the igure covering the functional group or the subfunctional group to which the Item belongs.
Third. Identify the Item on the igure and note the number(s).
Fourth. Look in the repair parts list work packages for the igure and Item numbers. The NSNs and part
numbers are on the same line as the associated Item numbers.
2. When NSN is Known.
First. If you have the NSN, look in the STOCK NUMBER column of the NSN Index work package. The NSN is
arranged in NIIN sequence. Note the igure and Item number next to the NSN.
Second. Turn to the igure and locate the Item number. Verify that the Item is the one for which you are
looking for.
3. When Part Number is Known.
First. If you have the part number and not the NSN, look in the PART NUMBER column of the part number
index work package. Identify the igure and Item number.
Second. Look up the Item on the igure in the applicable repair parts list work package.
