The Airbus Helicopters SA.365 C3 Dauphin II is a twin-engined medium-weight transport helicopter for up to 2 crew and 13
passengers powered by two Turbomeca Arriel 1C2 Turbine engines. The twin-engine SA.365 was developed in 1973 by SNIAS
(Société Nationale Industrielle Aerospatiale) out of the single-engine SA.360 Dauphin. The SA.365 prototype F-WVKE, a
SA.360 fitted with 2 Turbomeca Arriel 1A Turboshafts, flew first on 24 January 1975. In 1977 production commenced with
the SA.365-C, with deliveries starting in 1978. An improved version of the SA 365C Dauphin II, the SA.365N flew
first on 31 March 1979. The SA 365N differs from the SA365C in having Arriel 1C turbine engines, a
re-profiled fuselage, fully retractable undercarriage and increased fuel capacity in new under-floor tankage.
Deliveries of the production model began in 1982. Deliveries of the AS.365 N2, equipped with two Turboméca
Arriel 1C2 turboshafts, started in 1990. From 1984, SNIAS operated under the name of Aérospatiale.
The helicopter divisions of MBB from Germany and Aerospatiale from France merged in January 1992 to form the Eurocopter
Group. A new Eurocopter designation was added: EC155 B1, originally known as the AS 365 N4. The Dauphin II is in use
in several military and civilian roles. The AS 565 Panther is the military version of the Dauphin. The AS 366 G1,
powered by two Textron-Lycoming LTS.101-750B-2 turboshafts, is used by the United States Coast Guard under the
designation HH-65A Dolphin. The Dauphin II is manufactured under licence in China as the Harbin Z-9 Haitung and in
Brasil as the Helibras MH-1. Already over 1100 AS 365/366/565 and EC155 versions have been manufactured.
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.
On 28 April 2006, the ITH "Christoph Reichelsheim" was
renamed "Christoph Hessen". The call sign "Christoph" is used for the
German lifeliner helicopters since 1970 and is derived of Saint
Christophorus, the Patron Saint for all travellers. The 1978-built
SA.365 C3 D-HAAK is operated by Heli-Flight since February 1995. It was
originally delivered as a SA.365C-1 and registered as YR-DFD in Romania. In
November 1988, the aircraft was registered D-HAAK in Germany as a SA.365C-3 Dauphin II by Arcus-Air
Logistic GmbH, Köln/Bonn. In March 2007, the D-HAAK was replaced in service as "Christoph Hessen" by the AS.365N
D-HFHE. In May 2007, Airbus Helicopters SA365 C3 D-HAAK received new colours and is
operated as before by Heli-Flight out of Reichelsheim.
