Embraer plans to begin assembling its new midsize Legacy 450 and 500 business jets at its Melbourne, Fla., campus by 2016. The company will break ground soon on a major new plant expansion at its Melbourne facility and expects to add 600 more jobs when it is fully up and running. Embraer already assembles Phenom 100s and 300s at the Florida facility. Meanwhile, Embraer Executive Jets senior vice president Jose Eduardo Costas added that certification of the fly-by-wire Legacy 500 is “imminent.”
