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 Until production ended in 2001, as the BO105 was superseded by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.
RTH (Rettungstransporthubschrauber) MBB BO.105CBS-5 D-HGSQ of the Bundesminsterium des Innern / Katastrophenschutz was
seen at the helipad of Luftrettungszentrum Bielefeld in Germany in service as 'Christoph 13'. Air Rescue Station
Bielefeld is situated close to the Bielefeld-Rosenhöhe hospital. The Bundesgrenzschutz Fliegerstaffel Nord flies the
helicopters of 'Christoph 13'. Operations of 'Cristoph 13' in the Bielefeld area started on 3 July 1976. The MBB BO.105CBS-5
in service as 'Christoph 13' at Air Rescue Station Bielefeld was replaced by an
Eurocopter EC135 T2+ on 20 August 2007. Call sign 'Christoph' is used for the German lifeliner
helicopters since 1970 and is derived of Saint Christophorus, the Patron Saint for all travellers. The 1997-built MBB BO.105CBS-5 s/n 924
was leased for a ten-years period by the BMI from Dayhaka General, and returned after the lease period to Eurocopter Deutschland. In February 1997,
the MBB Bo.105CBS-5 was registered D-HGSQ with BMI - Bundesministerium des Inneren, o/b BGS - Bundesgrenzschutz, Hannover. On 1 July 2005,
the Bundesgrenzschutz Fliegerstaffel Nord was renamed Bundespolizeifliegerstaffel Nord. In 2008, the helicopter was overhauled by Eurocopter
Germany, Donauwörth, and in 2009 offered for sale by AVINCO.On 21 September 2010, registration D-HGSQ was cancelled
as exported. On 12 October 2010, the MBB BO.105CBS-5 was restored to the German register with
a permit to fly as D-HSCH prior the export to Democratic Republic of Congo.
