Airworthiness
Section 02: Regulatory Vocabulary
Definition
The condition of an aircraft, engine, propeller, or part whereby it conforms to its approved type design and is in a condition for safe operation. Airworthiness is a composite concept that encompasses both initial airworthiness (the design meets the applicable airworthiness standards at the time of certification) and continuing airworthiness (the aircraft remains in conformity with the approved design and in a safe operating condition throughout its service life). An aircraft is legally 'airworthy' only when both conditions are met.
Where This Shows Up
Airworthiness approvals address the design and physical condition of the product itself. They are distinct from operational approvals, which address the qualifications, procedures, and capabilities of the operator. An airworthy aircraft operated by a non-qualified operator may still be unsafe.
