Airbus Helicopters (formerly Eurocopter Group) is the helicopter manufacturing division of Airbus Group. It is the largest in the industry in terms of revenues and turbine helicopter deliveries. Its head office is located at Marseille Provence Airport in Marignane, France, near Marseille. The main facilities of Airbus Helicopters are at its headquarters in Marignane, France and in Donauwörth, Germany, with additional production plants in Brazil (Itajubá,MG), Australia, Spain and the United States. The company was renamed Airbus Helicopters on 2 January 2014. Airbus Helicopters was formed in 1992 as Eurocopter Group, through the merger of the helicopter divisions of Aérospatiale and DASA. The companys heritage traces back to Blériot and Lioré et Olivier in France and to Messerschmitt and Focke-Wulf in Germany. Airbus Helicopters and its predecessor companies have established a wide range of helicopter firsts, including the first production turboshaft-powered helicopter (the Aérospatiale Alouette II of 1955); the introduction of the Fenestron shrouded tail rotor (on the Gazelle of 1968); the first helicopter certified for full flight in icing conditions (the AS332 Super Puma, in 1984); the first production helicopter with a Fly-by-wire control system (the NHIndustries NH90, first flown in full FBW mode in 2003); the first helicopter to use a Fly-by-light primary control system (an EC135 testbed, first flown in 2003); and the first ever landing of a helicopter on Mt. Everest (achieved by an AS350 B3 in 2005).
