Twin-engined light transport aircraft with accommodation for five to eight persons. The first prototype flew on 15 August 1961, powered by a Continental 194kW IO-470-A engine, and was smaller than subsequent B.206. The second prototype had increased dimensions and a 231kW Rolls-Royce/Continental GIO-470-A engine. The initial commercial version was the B.206 Series I or B.206C. The B.206R was the military production version, ordered for communications and ferrying duties with the RAF under the name Basset CC.l. The B.206-S was a development of the Series I with supercharged engines and other refinements. Deliveries included two ambulance models for the Royal Flying Doctor Service of New South Wales, Australia. By the close of 1969 40 B.206 Series I and II aircraft, 20 Bassets and two B.206Z pre-production types for the Ministry of Technology had been delivered.
