The Eurocopter EC 135 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 and went into series production in 1996 at Donauwörth. After
German certification was granted on 14 June 1996, the first customer delivery was on 31 July that year. Over
600 have been delivered since the helicopter entered service in 1996 with the German rescue company DRF - Deutsche
Rettungsflugwacht e.V.
RTH (Rettungstransporthubschrauber) EC135P2 D-HLDM "Christoph" was photographed during the training for
the 75th Dutch TT at the helipad of the "Circuit van Drenthe" near Assen in the Netherlands. Before the helicopter was registered
D-HLDM with the ADAC Luftrettung GmbH in April 2005, Eurocopter Germany used test-registration D-HECL for the 2005-built Eurocopter EC135 T2+ c/n 0392.
The D-HLDM was operated as HEMS-helicopter during the Dutch TT from June 23-25, 2005. The D-HLDM "Christoph"
was in service with the ADAC just 3 weeks before it was photographed as HEMS-helicopter in Assen. 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.
