The devlopment of MBB BO 105

Ludwig and Emil Bölkow Weiland had since 1955 in the company Bölkow Entwicklungen KG designed helicopters. When considering the lay-out for a new project, they found that the market needed a light helicopter, designed for security (and more generally by two redundant design of all major systems, as well as a high-lying rotor) maintenance-friendly, easy to fly, particularly suited for rescue missions and economical to maintain. The government of the BRD found this concept good and granted the company economic support.

The Bo 105A made its maiden flight in February 1967. The German Civil Aviation Authority certified the helicopter in October 1970 and production for German civil and law enforcement organizations began shortly afterwards. Further safety certification by the FAA was granted in April 1972 and was followed with orders to the United States.

The Bo 105C was developed in 1972 and the German Ministry of Defence selected this model as light observation helicopter, purchasing 100 helicopters in 1977. A specialist anti-tank version armed with Euromissile HOT missiles and designated as the Bo 105PAH-1 was procured by the German Army around the same time, with a total of 212 eventually being delivered.

In 1976, the Bo 105CB was developed with more powerful Allison 250-C20B engines. This was further developed as the Bo 105CBS with the enlargement of the fuselage by 10 inches to meet American market demands for emergency medical service operations. This version was known as the Bo 105 Twin Jet in the United States.

In 1984, the Bo 105LS was developed with the enlarged fuselage of the Bo 105CBS combined with more powerful Allison 250-C28C engines to increase the maximum take-off weight.

Production ended in 2001, due to the Bo 105 being superseded by the more modern Eurocopter EC 135, after 1 406 machines had been built.

Being the first light twin-engine helicopter in commercial service, it gained widespread use over rural areas (police and EMS / Mede vac) as well as offshore.

The helicopter has been sold to an impressing lot of countries. These have purchased military variants:

Albania, Bahrain, Bophuthatswana, Brunei, Canada, Chile, Colombia, Germany, Indonesia, Iraq, Jordan, Kenya, Lesotho, Mexico, Netherlands, Niger, Nigeria, Papua New Guinea, Peru, Philippines, Sierra Leone, South Korea, Spain, Sudan, Sweden, Trinidad and Tobago, United Arab Emirates and Uruguay.
Civilian versions of the helicopter have been sold to these countries:
Argentina, Austria, Canada, Chile, Czech Republic, Germany, Greece, Indonesia, Israel, Iran, Jordan, Netherlands, Peru, Philippines, Russia, Spain, Turkey, South Africa, United Kingdom and United States.
