What is Certification



Certification Body (Air Forces, FAA, TC, EASA
and etc)
Purpose – not only in airplane but also out of
airplane (example, 9.11 USA, RC Airplane hurt
a lady in Han river, RC in Jail when president
visit(?))
Aircraft manufacturer should provide
airworthiness proof by tests, simulation and
others. – Type Certification will be issued after
completion of certification (ex, Landing Gear)
