The Eurocopter AS.355 is a twin-engined light utility helicopter that can accommodate up to 7 passengers.
Development of the Ecureuil started in the early 70s under the Aérospatiale banner with the
single-engined AS 350. The first flight of an Aerospatiale AS-350 took place on 27 June 1994. A
twin-engine version of the AS 350, the AS-355 Ecureuil 2 flew first on 28 September 1979.
The Eucureuil 2 entered production as the AS-355E. The AS-355F with a higher max takeoff weight replaced
the AS-355E early 1982 in production. The AS-355F was followed by the AS-355F-1 in January 1984 and
AS-355F-2 in December 1985. The AS-355 Ecureuil 2 is marketed in North America as the "TwinStar".
The helicopter divisions of MBB from Germany and Aerospatiale from France merged in January 1992 to form the
Eurocopter Group.
