The Joint Aviation Authorities (JAA) was an associated body of the ECAC 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. Using only the above description and what you know about the world, "The Joint Aviation Authorities is the most important associated body responsible for developing and implementing common safety regulations across European States." is definitely correct, incorrect, or inconclusive?
