Quote from the EASA website from 2006
Switzerland will tomorrow officially become a member of the European Aviation Safety Agency. It is the fourth non-EU country to adopt European Union aviation safety legislation after Norway, Iceland and Liechtenstein. Patrick Goudou, Executive Director of the Agency, said: “I welcome Switzerland’s membership. It is animportant step towards a more integrated safety system in Europe and underlines the key role of the Agency in this system”.
The four non-EU countries are represented in the Agency’s Management Board and nationals of these countries are eligible to work for the Agency.
