D-HGSB MBB Bo.105 CBS-5 c/n S-13 - Luftrettung / BMI "Christoph 34" - air rescue station Güstrow in Germany - 29 June 2007 lifeliner helicopters

The MBB Bo.105 is a five-seat lightweight, general-purpose helicopter. Development of the Bo.105 started back in 1959 when Bölkow designed the Bo.103 helicopter. The Bo.103 single-seat flew first on 14 September 1961. The two-seat Bo.104 followed this study-project. Due to marketing reasons this project was stopped in favour of the five-seat Bo.105. Design work for the Bo.105 began in July 1962. Construction of the first of three prototypes began in 1964. The first Bo.105 prototype D-HAKO s/n V-1 was destroyed in ground tests and written off in October 1966. The second machine, D-HECA s/n V-2, was powered by two 317shp Allison 250C18 turboshafts and on 16 February 1967, the BO105 took off for its maiden flight in Ottobrunn (near Munich), Germany. On 14 May 1969, Messerschmitt-Bölkow-Blohm GmbH (MBB) was formed and development of the Bo.105 continued with the first production BO-105A, D-HABV s/n S-1, flying on 11 April 1970. The breakthrough came in 1974 when the German Army ordered the BO 105 as a connection and observation helicopter. In January 1992, the MBB Bo 105 became part of the large helicopters types row of Eurocopter when the helicopter divisions of MBB from Germany and Aerospatiale from France merged to form the Eurocopter Group. In 1993, the BO 105 CBS with a 25cm fuselage stretch and extra window was certificated. Over the years, license agreements for the BO105 CB/CBS versions with the Philippines, Indonesia and Spain were concluded, and for the BO105 LS, a cooperation agreement with Canada. Until production ended in 2001, as the BO105 was superseded by Eurocopter’s EC135, a total of 1,406 BO105s had been delivered to 55 customer nations.

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.

RTH (Rettungstransporthubschrauber) MBB BO.105CBS-5 D-HGSB "Christoph 34" of the Bundesminsterium des Innern / Katastrophenschutz was photographed at the helipad of Luftrettungszentrum Güstrow in Mecklenburg-Vorpommern, Germany. This Air Rescue Station is situated close to the Güstrow hospital. The Bundespolizeifliegerstaffel Nord flies the helicopters of “Christoph 34”. Operations of "Cristoph 34" in the Güstrow area started on 16 November 1992. The 1971-built MBB Bo.105CBS-5 s/n S-13 D-HGSB was registered first as a BO.105A with the BMI - Bundesministerium des Inneren, o/b BGS - Bundesgrenzschutz in December 1971. Since the airframe was upgraded in August 1973 to a BO.105C and later to a BO.105CBS-5 model. Call sign "Christoph" is used for the German lifeliner helicopters since 1970 and is derived of Saint Christophorus, the Patron Saint for all travellers. On 1 July 2005, the Bundesgrenzschutz Fliegerstaffel Nord was renamed Bundespolizeifliegerstaffel Nord. On 15 November 2007, the MBB BO.105CBS-5 in service as "Christoph 34" was replaced by Eurocopter EC135 T2+ D-HZSJ. After being withdrawn from service with the Bundesminsterium des Innern/Katastrophenschutz, the MBB BO.105CBS-5 D-HGSB was sold via VEBEG. In November 2008, the D-HGSB was registered with Darda Systems, Donaueschingen. On 30 June 2009, registration D-HGSB was cancelled as exported to Switzerland. On 3 July 2009, the helicopter was registered HB-ZJF in Switzerland as a MBB BO.105S with Skymedia AG, Zürich.
