Section 3: Parts Lists
Parts information
This section contains reference designation lists that provide descriptive and provisioning
information for all electrical and mechanical parts that have an assigned reference designation and
form a part of the subject equipment.
Family tree
Figure 3.1 depicts the family tree for the subject equipment. It is based on the descending order of
the reference designation hierarchy and identifies all assemblies that have an assigned Nautel
configuration control number.
How to locate information about a specific part
To locate the information for a specific part, the assigned reference designation for the part must be
known. In addition, the Nautel nomenclature (e.g., NAA56/01D) assigned to the assembly
containing the part or the full reference designation, including the reference designation of all higher
assemblies, must be known.
When the nautel nomenclature is known:
• Refer to the family tree (Figure 3.1) and identify the block(s) associated with the Nautel
nomenclature. At the bottom of the main family tree block, a reference is made to “See Part
Number Index Tables”. Locate the part's reference designation in the identified reference
designation list in this section, noting they are sorted alphanumerically.
When the reference designation is known:
• Refer to the family tree depicted in Figure 3.1 with the full reference designation.
• Follow the family tree branches to the block that represents the lowest level assembly
assigned a Nautel configuration control number. Then locate the part number index table for
that Nautel configuration control number.
• Locate the part's reference designation in the specified table.
