airworthy

Airworthy is a status applied to an aircraft indicating that it conforms to its approved design and is in a condition for safe operation in the air. It is determined by compliance with applicable airworthiness requirements, including the type design, maintenance, and documented conformity. Airworthiness is not a guarantee of safety, but a condition that the aircraft is fit for flight under its intended use.

Regulatory framework and certification: Airworthiness standards are set by international bodies such as ICAO and implemented by national authorities (for example, the FAA in the United States and EASA in the European Union). An aircraft becomes airworthy only after a formal determination by the authority or its delegated inspector that it conforms to its type design and is in a condition for safe operation. In many jurisdictions, this is evidenced by an airworthiness certificate, which may come in standard forms for regular operations or special forms for experimental, light-sport, restricted, or other categories.

Continuing airworthiness and records: After initial certification, ongoing compliance is required to maintain airworthiness. This includes scheduled inspections, routine maintenance, and adherence to airworthiness directives and service bulletins issued by the manufacturer or authorities. Operators maintain records that document conformity, inspections, repairs, and any modifications. If damage, wear, or a modification affects conformity, the airworthiness status can be suspended or withdrawn until compliance is restored.

Scope and limitations: Airworthiness applies to the aircraft and its equipment as designed and maintained, not to the pilot or the operating environment. It is one essential component of safe flight, complemented by proper pilot qualifications, weather assessment, and adherence to approved procedures.
