Which of the following would NOT be included in the compliance section of an AD?

The compliance section of an Airworthiness Directive (AD) typically outlines the actions required to address safety concerns regarding aircraft components or systems. These actions often include required inspections, part replacements, and specifics on operating procedures that must be followed to ensure compliance with the directive.

Maintenance training updates would generally be considered supplementary information rather than a direct requirement for compliance. While training may be important to ensure that maintenance personnel are capable of performing required inspections and replacements effectively, it does not constitute a necessary action that affects the airworthiness of the aircraft in the context of the AD. Therefore, it is excluded from the compliance section, which focuses on the specific actions needed to be taken to maintain the aircraft's safety and regulatory standards.
