Joint Aviation Authorities

The Joint Aviation Authorities (JAA) was an associated body of the European Civil Aviation Conference representing the civil aviation regulatory authorities of a number of European States who had agreed to co-operate in developing and implementing common safety regulatory standards and procedures. It was not a regulatory body, regulation being achieved through the member authorities. It was in existence from 1970 until disbanded in 2009. Its headquarters were located in Hoofddorp near Schiphol airport in Netherlands.

JAA issued the Joint Aviation Requirements (JAR), intended to establish minimum requirements for air safety.

In implementing the so-called FUJA Report, JAA entered into a new phase as of 1 January 2007. In this new phase the former "JAA" became "JAA T" (Transition). JAA T consisted of a Liaison Office (JAA LO) and a Training Office (JAA TO). The offices of JAA LO were located in the premises of the European Union Aviation Safety Agency (EASA) in Cologne, Germany.
