How long does the Airworthiness Certificate of an aircraft remain valid?

• A. As long as the aircraft is maintained and operated as required by Federal Aviation Regulations
• B. For 12 months
• C. For the life of the aircraft
• D. While the owner holds it

Answer: (A)

Airworthiness is about ongoing compliance with the regulations, not a fixed expiration date. The Airworthiness Certificate remains valid as long as the aircraft continues to meet the required airworthiness standards and is maintained and operated per the Federal Aviation Regulations. It isn’t tied to a calendar year or to the current owner; the certificate can stay in effect through ownership changes as long as maintenance, inspections, and ADs are kept up and the aircraft remains airworthy.
