The Federal Aviation Administration (FAA) makes it apparent that only airworthy aircraft should be operated. Airworthiness is the measure of an aircraft’s suitability for safe flight. The airworthiness certificate issued by the FAA, certifies that the aircraft is airworthy.
The FAA puts out what are called Special Airworthiness Information Bulletins, or SAIBs, to alert, educate, or make recommendations to the aviation community.
For more information please review this Special Airworthiness Information Bulletin.
