Aircraft safely is of interest to everyone around the world. To address aircraft safety there are certification processes in place where two organizations with the greatest involvement are the FAA (Federal Aviation Agency) in the US, and the EASA (European Union Aviation Safety Agency) in Europe.
Certification is how the FAA manages risk through safety assurance. It provides the FAA confidence that a proposed product or operation will meet FAA safety expectations to protect the public. Certification affirms that FAA requirements have been met.
