Civil aviation aircraft have the property of ensuring the safety of navigation and crew within the prescribed scope of use. The airworthiness of an aircraft is measured by its compliance with the corresponding airworthiness standards. The safety of an aircraft is not only determined by the body of the aircraft, but also by the engines and equipment installed on it.
Therefore, the airworthiness of an aircraft includes the airworthiness of the aircraft’s fuselage, engine, and airborne equipment. The airworthiness mark of an aircraft is the obtaining of the corresponding certificate of airworthiness. The Certificate of Airworthiness is a certification file issued by the airworthiness management agency after reviewing the aircraft to confirm that it meets airworthiness standards.
Obtaining an airworthiness certificate for an aircraft only shows that it is safe to use, but whether it can be used safely depends on other factors after use. The airworthiness of an aircraft after it has been put into use is generally referred to as “continuing airworthiness”, which includes airworthiness review and monitoring of use and maintenance to ensure flight safety.
The certification standard deals with the airworthiness of use and maintenance. When an aircraft exhibits general safety-related flaws during use, the airworthiness management agency can issue corresponding documents, often called “airworthiness notices”, to notify the relevant units for inspection and removal.
If the situation is serious, the “Adequate Aeronautical Notification” means that the flight of this type of aircraft must be interrupted, not being able to resume the flight until the unsafe factors are eliminated.
