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 Until production ended in 2001, as the BO105 was superseded by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-HGSB 'Christoph 34' of the Bundesminsterium des
Innern / Katastrophenschutz was seen 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'.
On 16 November 1992, operations of 'Cristoph 34' in the Güstrow area started with the MBB BO.105CBS-5.
On 15 November 2007, the MBB BO.105CBS-5 in service as 'Christoph 34' was replaced by
Eurocopter EC135 T2+ D-HZSJ.
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 1971-built MBB Bo.105CBS-5 s/n S-13 D-HGSB was registered as
a BO.105A with the BMI - Bundesministerium des Inneren, o/b BGS - Bundesgrenzschutz in December 1971.
In August 1973, the airframe was upgraded to a MBB BO.105C. In 1980, the D-HGSB was painted in the orange
'Katastrophenschutz' colors. In 1993, the airframe was modified to a BO.105CBS-5 model and painted in the
orange BMI colors with Luftrettung titles. In 1994, the helicopter was seen first active as 'Christoph' in
service with Bundesgrenzschutz Fliegerstaffel Nord. On 1 July 2005, the Bundesgrenzschutz Fliegerstaffel
Nord was renamed Bundespolizeifliegerstaffel Nord. In 2008, after being withdrawn from service with the
Bundesminsterium des Innern/Katastrophenschutz, the MBB BO.105CBS-5 D-HGSB was sold via VEBEG. On 23 October
2008, the D-HGSB was registered with Darda Systems, Donaueschingen. The airframe was overhauld by Eurocopter
Deutschland. 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, Zürich. On 26 November
2015, registration HB-ZJF was cancelled as exported to South Korea. On 4 December 2015, the helicopter was
registered HL9618 with Sejin Aviation Co.
