Airspeed Envoy

From PlaneSpottingWorld, for aviation fans everywhere

Airspeed AS.6 Envoy was a British light, twin-engined transport aircraft designed and built by Airspeed Ltd. at Portsmouth Aerodrome, Hampshire.

Development

The Envoy was designed by N.S. Norway and A. H. Tiltman as a twin-engined development of the Courier. Co-designer Norway also wrote novels under the pen name Nevil Shute. It used the same wooden construction, outer wing panels and aft-retracting main undercarriage legs. The prototype G-ACMT first flew on June 26, 1934 and in July 1934, the aircraft was presented to the public for the first time at an exhibition by the Society of British Aircraft Constructors (SBAC) at Hendon.

Operational use

The first production Envoy I G-ACVH was used as a demonstrator, the second was delivered to Lord Nuffield. Lord Nuffield's aircraft was due to fly in the MacRobertson Air Race from England to Australia in 1934, but the aircraft was damaged and withdrawn from the race. Another aircraft, a specially modified version with long-range tanks (the AS 8 Viceroy) got as far as Athens before leaving the race due to damage.[1]

Orders soon came from the whole Commonwealth. Two aircraft went to the Ansett Airlines in Australia. North Eastern Airways also used the AS.6. In Czechoslovakia, the CSA ordered four AS.6 Envoy JC in 1937.

The Airspeed AS.6 Envoy also entered the Air Forces of different countries. The British Royal Air Force used a few AS.6 in a military configuration. The aircraft was used in the Air Forces of Spain, Japan, South Africa, Finland and China and some others. Seven machines were ordered for joint use by the South African Air Force and South African Airways, with three being delivered in military form and four delivered to South African Airways, where they were used on the air route between Johannesburg - Bloemfontein - Port Elizabeth on 12 October 1936.[2] Each of these seven aircraft could be transformed by a work crew of four within four hours from the transportation version into a light bomber or reconnaissance aircraft. In this configuration the crew consisted of four; pilot, navigator, radio operator and gunner.

In October 1936, the British Air Ministry ordered 136 Envoys for the role of crew-training. These further developed aircraft were given a new designation; Airspeed AS 10 Oxford.

Japan

Six Envoy-Is were delivered to Japan in 1935 for services linking Japan with Manchukuo. These were followed by 10 aircraft license built by Mitsubishi at Nagoya. The aircraft were named Hina-Zura (en: Flying Crane). The aircraft were used by the Japan Air Transport and Manchukuo National Airways; it is believed the rest were operated by the Imperial Japanese Navy under the designation LXM.

Wartime

During the Spanish Civil War, ten AS.6 Envoys were obtained by the Spanish Republicans, with the Nationalist side using two, including one that defected from the Republicans, [3] as transport, reconnaissance aircraft or light bombers.[4]

In May 1937, the British King George VI traded his de Havilland Dragon Rapide for an Airspeed AS.6J Envoy III. The AS.6's good stability and flaps, as well as its low landing speed (less than 100 km/h) was decisive. The aircraft received the registration G-AEXX and was painted in distinctive red and blue colours .[5]

During the Second World War, the German Luftwaffe captured some machines and used them as trainer aircraft. The Luftwaffe gave one aircraft to Finland on 22 January 1942, as reparation for the accidental shooting down of a Finnish de Havilland Dragon Rapide. This aircraft was used between 1942 and 1943. Likewise, one aircraft was used between 1941 to 1943 by the Slovaks.[citation needed]

Postwar

One of the RAF Envoy IIIs survived the war and operated as G-AHAC for civil charter operators until it was scrapped at Tollerton airport, Nottingham in 1950.
