Which records shall the owner or operator keep to show compliance with an applicable Airworthiness Directive?

• A. Aircraft maintenance records
• B. Flight logs
• C. Registration
• D. Insurance policy

Answer: (A)

Demonstrating compliance with an Airworthiness Directive relies on the records that prove the required actions were actually performed. The aircraft maintenance records are the official record of any AD actions—showing the specific directive number, the exact maintenance or inspection done, the date, the aircraft identification, and the technician or authority who completed it. These records provide auditable proof that the directive was complied with, which is the core purpose of AD records. Flight logs track flight activity, not compliance with mandated actions. Registration simply shows identity and legal ownership, not whether AD actions have been completed. Insurance policy relates to coverage and risk, not airworthiness findings. Keep the maintenance records current and accessible so authorities can verify AD compliance whenever needed.
