Lla Cloche 206 est une famille d’hélicoptères bipales, monomoteurs et bimoteurs, fabriqués par Bell Helicopter à son usine de Mirabel, au Québec. Développé à l’origine sous le nom de Bell YOH-4 pour l’armée des États-Unis’s Light Observation Helicopter program, it was not selected by the Army. Bell redesigned the airframe and successfully marketed the aircraft commercially as the five-place Bell 206A JetRanger. The new design was eventually selected by the Army as the OH-58 Kiowa. Bell also developed a seven-place LongRanger, which was later offered with a twin-engined option as the TwinRanger, while Tridair Helicopters offers a similar conversion of the LongRanger called the Gemini ST. The ICAO-assigned model designation « B06 » est utilisé sur les plans de vol du JetRanger et du LongRanger, et la désignation « B06T » est utilisé pour les TwinRangers bimoteurs.
