The Agusta-Bell AB.206B JetRanger II is a 5-seat light utility helicopter powered by a single Rolls Royce Allison 250-C20 turbine engine. In 1961, Bell developed Model 206 as the OH-4A to meet the U.S.Army requirements. The OH-4A flew first on 8 December 1962. However the Bell OH-4A didn't win the competition, the helicopter was a success as the Bell 206 Jet Ranger. The prototype of this five-seat commercial model, the Bell 206A JetRanger N8590F, flew on 10 January 1966. Bell received FAA certification for the helicopter on 20 October 1966, and deliveries of the Model 206A powered by a 317 shp Allison C18A engine, started in January 1967. In the early 1970s production switched to the Model 206B JetRanger II with a 400 shp 250-C20 turboshaft. The Model 206 was built under license by Agusta in Italy as the AB.206 Jet Ranger. More than 4800 206Bs and 1700 206Ls have been produced since the introduction of the 206A JetRanger on 13 January 1967, when the first two production aircraft were delivered to customers. Since then, Bell has delivered five different generations of the commercial 206 with its 206A/B JetRangers and 206L/L1/L3/L4 LongRangers. Bell 206 aircraft are currently produced at Bell Helicopter's facility in Mirabel, Canada. Early 2008, Bell Helicopter, a Textron Inc. company, announced that it is terminating production of its 206B3 helicopter model. All current customer commitments for the production of its 206B3 helicopter models will be met through 2010.
