The Airbus Helicopters EC135 is a lightweight five/seven seat
twin-turbine-engine multi-role helicopter with a radius of 720 km. The
EC135 is offered with either Turbomeca Arrius 2B2 or Pratt and Whitney
Canada PW206B2 engines. A militarized version called the EC 635 has been
developed from the EC 135. 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 and went into series production in 1996 at
Donauwörth. After German certification was granted on 14 June 1996, was
the first customer delivery on 31 July that year. Next to the EC135 a
special military version was developed designated the Eurocopter EC635.
Over 1300 EC135 airframes have been delivered since the helicopter
entered service in 1996. The ICAO Aircraft Type Designator for the EC135 helicopters is
EC35. In March 2015, Airbus Helicopters renamed its entire product line
to better reflect its closer allignment with ist parent company and
simplify the naming convention for the portfolio. Therefore, the EC135
T3/P3 has been renamed as “H135” as stated in revison No.EASA.R.009 Issue: 07
of the Type Certificate Data Sheet for EC135 dated 18 March 2015.
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 2 September 2016, Eurocopter EC135 P2 D-HHTS was seeen in service as RTH (Rettungstransporthubschrauber) "Christoph Europe 2" at the helipad
of ADAC-Luftrettungszentrum Rheine, Germany. This helipad is situated at the roof of a parking garage near railway station Rheine West. On 14 January 1982,
operations of a RTH (Rescue helicopter) in Rheine began as "SAR76". Until 30 January 1998, the service was flown as "SAR 76" by the
Luftwaffe with a Bell UH-1D. On 31 January 1998, the Luftwaffe was replaced by ADAC Luftrettung and the RTH service in Rheine was renamed "Christoph
Europe 2". Callsign "Christoph" is used for the German lifeliner helicopters since 1970 and is derived of Saint Christophorus, the Patron
Saint for all travellers. ADAC Luftrettung started its RTH operations in Rheine with an EC135 P1 helicopter, that was replaced by an EC135 P2 in 2005.
The current facilities of the ADAC-Luftrettungszentrum Rheine were opened in June 2003. The ADAC helicopter was based before near the "Mathias-Hospital"
in Rheine, Germany. The 2005-built Eurocopter EC-135 P2 D-HHTS was registered in Germany on 26 January 2005 and handed over to ADAC Luftrettung GmbH on
28 January 2005. EC135P2 D-HHTS is used to operate as "Christoph Europe 2". On 26 December 2009, EC135 P2 D-HHTS "Christoph Europe 2" was
damaged in a hard landing at the helideck of Universitätsklinikum Münster. The helicopter had to be transported by road to Bonn-Hangelar for repairs by ALT.
Since 2012, the D-HHTS is equipped with the new Inlet Barrier Filter (IBF).
