The Beagle B.206 is a 1960s British seven-seat twin-engined liaison and communication aircraft built by Beagle Aircraft Limited at Shoreham Airport and Rearsby Aerodrome.

Design and development

The design of a twin-engined light transport began in 1960 and the prototype registered G-ARRM (designated the B.206X) first flew from Shoreham Airport, West Sussex on 15 August 1961.[1] The prototype aircraft was a five-seat all metal low-wing monoplane powered by two Continental flat-six engines. Owned since 1990 by Brooklands Museum then loaned to the Bristol Aero Collection before eventually being restored by a team of volunteers at Shoreham Airport, it was loaned to the Farnborough Air Sciences Trust Museum at Farnborough, Hampshire from 2011 until 2017. With the expiry of the loan agreement, it was dismantled and transported from FAST to Brooklands by road on 3 August 2017.

The second prototype (registered G-ARXM and designated B.206Y) was slightly larger with a larger-span wing and seating for seven. Two aircraft (designated B.206Z) were built for evaluation by the Ministry of Aviation at Boscombe Down and an order for twenty aircraft (designated B.206R) for the Royal Air Force followed.[1][2] The RAF aircraft were designated Basset CC.1 and were built at Rearsby Aerodrome, Leicestershire.

Initial production was the Series 1 aircraft which were powered by 310 hp Rolls-Royce Continental GIO-470A engines, and the first aircraft (G-ASMK) first flew on 17 July 1964. This aircraft was then converted as the first Series 2 aircraft with 340 hp Continental GTSIO-520C turbocharged engines and first flew as such on 23 June 1965.[1] The production Series 2 (initially known as the B.206S) was also fitted with a large freight door. The aircraft was soon in demand with air taxi companies and as a light transport for companies. Three aircraft were delivered to the Royal Flying Doctor Service in Australia.[3]

A Series 3 was developed with a raised rear fuselage to carry 10-passengers but only two were flown as such, one modified from a Series 2 airframe (G-35-28 c/n B.074) was used as the "Aerodynamic Test Vehicle" and later re-converted back to a Series 2 as G-AXPV[4] and the second (G-AWLN, c/n B.080) which was converted on the production line and ultimately sold in Brazil;[5] a third airframe (B.037, which had been damaged in production) was converted as a mock-up only and never flown.[6] When the company needed the room at Rearsby to build the Beagle Pup, production of the B.206 ended with the 79th aircraft, (c/n B.080). Four further fuselages and a number of fuselage sections had also been constructed but were never completed.[7]

Operational history

Ex RAF Basset CC.1 at Asuncion Paraguay in 1975

A competition was held at RAF Northolt in March 1963 between the B.206 and the de Havilland Devon for an aircraft to replace the Avro Anson, resulting in 20 Bassets being ordered for the RAF. The first delivery to RAF communications squadrons was made in May 1965. It was powered by two Rolls-Royce/Continental GIO-470 six cylinder horizontally-opposed engines giving it a maximum speed of 220 mph and a range of 1,645 miles. Up to eight persons could be carried.

The Northolt aircraft were originally based at RAF Bovingdon near Watford, Hertfordshire with the Southern Communications Squadron until the 'SCS' moved to Northolt and became 207 Squadron on 4 February 1969. Another squadron, the Northern Communications Squadron, operated Bassets from RAF Topcliffe near Thirsk in North Yorkshire, later becoming 26 Squadron at RAF Wyton. Most aircraft were removed from RAF service on 2 May 1974 and sold for civil use.

Beagle B.206 Series 2 operated by Air Kilroe on charter flights from Manchester Airport during the late 1970s.

The first civil-ordered aircraft (a Series 1 registered G-ASWJ) was delivered in May 1965 to Rolls-Royce Limited at Hucknall. In 1975, Rolls-Royce retired this aircraft and donated it to RAF Halton for use by apprentices as 8449M; it is now with the Midland Air Museum at Coventry[8]

An unusual use was for one of the first aircraft registered G-ATHO which was bought by Maidenhead Organ Studios Limited for transporting electronic organs.[3] Other examples were operated by UK-based air charter firms including Air Kilroe.

The type was sold to and operated by civilian firms and individuals in several countries including Australia, Brazil and the United States. Bassets were sold after RAF service to the United States and Paraguay.
