Which of the following does NOT fall under Maintenance Instruction Manuals?

Maintenance Instruction Manuals (MIMs) are essential resources that provide guidelines and procedures for maintaining various components and systems within aviation operations. These manuals typically cover a wide range of equipment, ensuring that all aspects of maintenance are documented for reference and adherence to safety and operational standards.

Aircraft, weapons systems, and support equipment all involve specific maintenance procedures and requirements that are critical to ensuring proper functionality and safety. Maintenance manuals for these components outline operational capabilities, maintenance checks, and troubleshooting processes, as they are integral to the overall effectiveness and reliability of military and civilian aviation systems.

However, engine performance metrics are generally not included in Maintenance Instruction Manuals. While MIMs might reference general maintenance requirements for engines, performance metrics are typically found in separate documentation focused on engine specifications and performance parameters. This data is important for operational assessments and performance checks but does not directly relate to maintenance procedures as outlined in MIMs. Thus, engine performance metrics do not fall under the umbrella of what Maintenance Instruction Manuals are designed to cover.
