The Airbus Helicopters H125 (previously the Eurocopter AS350) Écureuil, or Squirrel, is a single-engine light utility helicopter designed and originally manufactured by the French corporation Aérospatiale, later by Eurocopter, which became Airbus Helicopters. In North America, the H125 is marketed as the AStar. The AS355 Ecureuil 2 is a twin-engine variant, marketed in North America as the TwinStar.
The Eurocopter EC130 is a derivative of the AS350 airframe and is considered by the manufacturer to be part of the Écureuil single-engine family.
