The Airbus Helicopters AS350 B3 is a single-engined utility helicopter that can
accommodate up to 7 passengers. Development of the AS 350 Ecureuil
started in the early 70s under the Aérospatiale banner. The first flight
of an AvcoLycoming LTS101-powered machine took place on 27 June 1994.
The second prototype was fitted with an Arriel 1A and took to the air on
14 February 1975. Certification (with a Turboméca Arriel 1B turboshaft
powerplant) was achieved on 27 October 1977. The single-engined AS 350B2,
powered with a Turbomeca Arriel 1D1 engine was certified in April 1989.
The helicopter divisions of MBB from Germany and Aerospatiale from
France merged in January 1992 to form the Eurocopter Group. The
Eurocopter AS350 B3 is a high-performance version of the AS350 series, powered by a Arriel
2B engine equipped with a single channel (DECU) Digital Engine Control
Unit with a mechanical backup system. The AS350 B3, made its first

As a result of the merger between the Eurocopter parents Aérospatiale-Matra; DaimlerChrysler Aerospace (DASA)
and Construcciones Aeronàuticas Sociedad Anonima (CASA) in July 2000, the Eurocopter group became a division of the new formed
EADS (European Aeronautic Defence and Space company). Taking off into 2014, EADS was rebranded as "Airbus Group". Uniting
all its activities under a single brand, its helicopter division Eurocopter was rebranded as Airbus Helicopters on 8 January 2014.
