What does 'current certification status' refer to in airworthiness?

• A. Pilot's medical certificate.
• B. Operator's business license.
• C. Current certification status refers to the current validity of the aircraft's airworthiness certificate and compliance with applicable ADs.
• D. Air traffic controller's credentials.

Answer: (C)

Current certification status in airworthiness means the aircraft is legally permitted to fly because its airworthiness certificate is valid and the aircraft is in compliance with all applicable ADs (airworthiness directives) and required maintenance. The airworthiness certificate confirms the aircraft conforms to its approved design and is in a condition for safe operation. If the certificate is up to date and all ADs are complied with, the aircraft is considered airworthy; if an AD requires action that hasn’t been completed or the certificate has expired, the status is not current.

Other options relate to people or organizations (such as a pilot’s medical certificate, an operator’s business license, or air traffic control credentials) and do not determine the aircraft’s airworthiness.
