• Indexes: Comprehensive sections allowing users to look up parts by either their part number or description, referencing the relevant figure and item numbers.
• ECO/Revision History: A table tracking the revision levels and printing dates of various assemblies.

Users are instructed to locate a part in an illustration, find its numeric callout, and then refer to the associated parts list for its detailed information.
