The Eurocopter AS350 Ecureuil ("Squirrel") and AS355 Ecureuil 2 are a family of light helicopters originally manufactured by Aérospatiale (now part of Eurocopter Group). The AS350 (marketed as the AStar in North America) is the single-engined version, while the AS355 (TwinStar) uses two engines. The EC130B is a recent adaptation of the AS350 airframe.
