What documents validate an airworthiness certificate?

• A. Registration certificate.
• B. Airworthiness certificate.
• C. Registration, airworthiness certificate, and required markings.
• D. Pilot license.

Answer: (C)

For an aircraft to be considered airworthy, three items must be present and current: the airworthiness certificate itself, the registration certificate, and the required markings on the aircraft. The airworthiness certificate shows the aircraft meets safety standards; the registration certificate records who owns and is responsible for the aircraft; and the required markings (such as the visible registration number on the fuselage and tail) verify the aircraft’s identity and eligibility to operate. Having all three ensures the airworthiness status is properly validated. A pilot license does not affect the aircraft’s airworthiness.
