Which statement is true regarding Airworthiness Directives (AD's)?

The statement that noncompliance with Airworthiness Directives (ADs) renders an aircraft unairworthy is accurate because ADs are legally enforceable regulations issued by aviation authorities to address safety issues regarding specific aircraft or components. When an AD is published, it typically outlines a safety concern and specifies necessary actions to rectify the issue, which could involve inspections, modifications, or repairs. Failure to comply means that the aircraft may no longer meet the safety standards required for operation, thereby making it unairworthy.

This is critical for ensuring the safety of flight operations, as ADs are based on findings from ongoing safety assessments and incidents that could compromise an aircraft’s performance. Therefore, adherence to AD specifications is essential to maintain flight safety and airworthiness.
