Messerschmitt Bölkow-Blohm BO 105 CBS
Messerschmitt-Bölkow-Blohm Bo 105 was the first light twin-engine helicopter in the world and the first to be able to execute aerobatic manoeuvres, such as inverted loops.
The helicopter broke new ground technically and it quickly became popular as an air ambulance in many countries, including Norway. It was extremely manoeuvrable and the rotor system meant that the flight controls were very sensitive. It had a revolutionary hingeless rotor system, which at that time was a pioneering innovation.Bo 105 was the first helicopter of its size to have two engines, which was also a requirement for taking off and landing in urban areas. This obviously meant that it was safer, compared with single-engine helicopters, and this factor also meant that it was much used in environments such as Antarctica.
The Messerschmitt-Bölkow-Blohm Bo 105 first flew in 1967. It was introduced to the market in 1970. The helicopter was produced under licence in several countries, but most of the production took place in Germany and Canada. MBB became part of Eurocopter in 1991 and production of the BO 105 continued until 2001. The MBB BO 105 was built in both civil and military versions.
The museums helicopter
When the helicopter was with the Norwegian Air Ambulance Service it had the registration letters LN-OSZ and was operational from 1984 to 2005. The MBB BO 105 CBS is specially built for rescue and ambulance service and the cabin is therefore lengthened by approximately 25 cm compared with other models. The helicopter is painted in the colour scheme of the Norwegian Air Ambulance Service. LN-OSZ had no fixed base, but was rotated around to cover the planned maintenance schedules for the other helicopters.
On Monday 1 June 2015 LN-OSZ was hoisted down from its pedestal outside the entrance to the Norwegian Air Ambulance Foundation in Drøbak in order to be transported to the Norwegian Aviation Museum in Bodø. The ambulance helicopter is on display in the civil aircraft section and in due course it will be joined by the Sea King rescue helicopter.
The Air Ambulance's first helicopter could loop the loop and fly at more than 400 kph.
For 25 years this helicopter was the very symbol of a medical emergency helicopter in Norway
