        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 Until production ended in 2001, as the BO105 was superseded by 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. The ICAO Aircraft Type Designator for the MBB BO.105CBS-5 is B105  |

         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.  |

        The 1991-built Bölkow designed BO-105CBS-5 s/n S-871 (ex. D-HFNC; D-HMBL; N4346G) was registered D-HUPE 
        with the ADAC Luftrettung GmbH in November 1996. 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 GmbH through its subsidiary Air Lloyd Luftfahrt Technik 
        GmbH in Bonn-Hangelar offered the Bo105 CBS-5 D-HUPE for sale in 2006. 
        In March 2007, the D-HUPE was sold together with the BO105 CBS-4 
        D-HELM & D-HGAB and the BO105 CBS-5 D-HUHN for EMS work in Malaysia. 
        The registration D-HUPE was cancelled on 21 May 2007. Though operated in Malaysia, 
        the four ex-ADAC Luftrettungs helicopters were registered with Heli Trans Helicopters (Pty) Ltd. 
        in South Africa on 11 June 2007. The D-HUPE was registered as ZS-PWE. 
        In 2010, the helicopter was re-registered in Malaysia as 9M-LLG. On 23 June 2006, ADAC Luftrettung' Bo.105 CBS-5 D-HUPE "Christoph" was 
        seen at the helipad of the 'Circuit van Drenthe' near Assen, the Netherlands. The 
        D-HUPE was operated as EMS-helicopter during the 76th Dutch TT.  |
