To be airworthy an aircraft needs to meet all requirements in the Civil Aviation Rules related to design, manufacture, maintenance, modification, repair and safety. This covers the aircraft, components, fuel, and other materials essential to the operation of the aircraft.
Part 21 prescribes what is needed for an aircraft, product, or part to be certificated as safe to fly, including the approval of design changes such as repairs or modifications.
Rule 91.101 prescribes the need for aircraft to have a certificate of airworthiness which attests to their conformity to a design (the Type Certificate in the case of standard or restricted category aircraft), condition for flight, and compliance with CAA rules such as Part 26, 91 etc. Microlight aircraft require a flight permit. Hang gliders and paragliders do not require an airworthiness certificate.
