Where is Airworthiness Directives compliance typically recorded?

The compliance with Airworthiness Directives (ADs) is typically recorded in aircraft maintenance records. This is because ADs are legally enforceable regulations issued by the Federal Aviation Administration (FAA) that specify actions that must be taken to ensure ongoing airworthiness of an aircraft. The maintenance records serve as an official log that documents all maintenance actions performed, including compliance with any relevant ADs, which ensures that the aircraft remains safe for operation and meets regulatory requirements. Keeping accurate maintenance records is crucial for tracking the aircraft's compliance history and is also important for future inspections, resale, and overall safety management.
