The Airbus Helicopters EC135 is a lightweight five/seven seat
twin-turbine-engine multi-role helicopter with a radius of 720 km. The
EC 135 is offered with either Turbomeca Arrius 2B2 or Pratt and Whitney
Canada PW206B2 engines. Development of the Eurocopter EC135 started in
the 80s as the MBB Bo.108 Advanced Technology Helicopter. The prototype
BO108 with conventional tail rotor flew first on 15 October 1988. When
the helicopter divisions of MBB from Germany and Aerospatiale from
France merged in January 1992 to form the Eurocopter Group, the Bo108
program was transferred as well. An advanced low noise ducted 10-blade
Fenestron tail rotor was, next to other modifications, incorporated into
the design and the name of the helicopter was changed into Eurocopter
EC135. The prototype of the EC135 (D-HBOX s/n S-01) flew first on 15
February 1994. In 1996, the EC135 went into series production by
Eurocopter Deutschland in Donauwörth, Germany. After German
certification was granted on 14 June 1996, the first customer delivery
was on 31 July 1996. Next to the EC135 a special military version was
developed designated the Eurocopter EC635. Over 1200 EC135 airframes
have been delivered since the helicopter entered service in 1996. The
ICAO Aircraft Type Designator with Wake Category used to classify
aircraft types for the EC135 helicopters is EC35.
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.
NAH (Notarzthubschrauber) EC135 T1 OE-XEA "Christophorus 1" of the ÖAMTC Christophorus Flugrettungsverein
was photographed at the helipad of the Heliair location at Innsbruck Airport in Austria that was
opened on 22 May 2005. The "Christophorus 1" is based at Innsbruck Airport Kranebitten since 1 July 1983.
The callsign "Christophorus" is used for the Austrian lifeliner helicopters since 1983 and is derived
of Saint Christophorus, the Patron Saint for all travellers. This in 1997 built EC-135T1 was registered first D-HECK
with Eurocopter Germany for test flying. On 26 August 1997, the D-HECK was delivered to Helicopter Air Transport
GesmbH (heliair) and re-registered OE-XEA in August 1997. The OE-XEA was the first EC135 for Christophorus
Flugrettungsverein and entered service at Innsbruck as "Christophorus 1" on 5 September 1997.
The OE-XEA was registered with the Christophorus Flugrettungsverein in October 1997. After the EC135 was
re-registered D-HECN in late 1997 it was registered OE-XEA again with the Christophorus Flugrettungsverein, Wien, in January 1998.
In October 2007, the OE-XEA was registered with Helkopter Air Transport, Innsbruck.
In January 2011, the OE-XEA was registered with Helkopter Air Transport Gesellschaft, Wien.
