Which document certifies the airworthiness of an aircraft and its continued operation?

• A. FAA Form 337
• B. Airworthiness Certificate
• C. Supplemental Type Certificate
• D. Type Certificate Data Sheet

Answer: (B)

Airworthiness certification means the aircraft has been shown to meet its approved type design and is in a condition for safe operation. The official Airworthiness Certificate, issued by the aviation authority and displayed in the aircraft, confirms this status for ongoing operation. It stays valid as long as the aircraft remains in compliance with its design and continues to be maintained in airworthy condition, including complying with inspections and any applicable airworthiness directives. Other documents serve different purposes. FAA Form 337 records major alterations or repairs but does not by itself certify ongoing airworthiness. A Supplemental Type Certificate documents approval for a significant modification to the certified design, not the continuing airworthiness of the aircraft. A Type Certificate Data Sheet describes the approved design of a aircraft type, which is design approval information rather than a status of current operational airworthiness.
