Which regulation governs the issuance of an Airworthiness Certificate?

The issuance of an Airworthiness Certificate is governed by 14 CFR Part 21. This regulation outlines the requirements for the issuance of certificates and the overall airworthiness standards that must be fulfilled for an aircraft to be deemed safe for operation. Part 21 specifically addresses the procedures related to the certification of aircraft and aircraft components, including the necessary inspections and documentation needed to obtain an Airworthiness Certificate.

Understanding Part 21 is critical for aircraft operators and manufacturers, as it encompasses various aspects of the certification process, including transition from the production of the aircraft to the need for ongoing compliance with airworthiness standards. This regulation ensures that all aircraft meet essential safety and operational criteria before they are allowed to fly, thereby safeguarding public safety in aviation.

The other parts mentioned, while related to different aspects of aviation regulation, do not specifically govern the issuance of Airworthiness Certificates. Consequently, familiarity with Part 21 is essential for anyone involved in the maintenance, repair, or certification of aircraft.
