Which document is commonly used to indicate compliance with service bulletins or ADs?

• A. Pilot logbook
• B. Aircraft maintenance records
• C. Airworthiness certificate
• D. Registration

Answer: (B)

Recording compliance with service bulletins and airworthiness directives is done in aircraft maintenance records. These records document every maintenance action, including when a SB or AD is addressed, what work was performed, parts used, dates, hours, and the technician’s signature. They serve as the official history showing that required actions have been completed and are up to date, which is essential for ongoing airworthiness and for inspections or resale. The other documents—the airworthiness certificate, registration, and pilot logbook—do not indicate ongoing compliance with SBs or ADs: the airworthiness certificate shows eligibility at a point in time, registration identifies ownership, and the pilot logbook tracks flight time, not maintenance compliance.
