Avro Anson

The Avro Anson is a British twin-engine, multi-role aircraft that served with the Royal Air Force, Fleet Air Arm and numerous other air forces prior to, during, and after the Second World War. Named after British Admiral George Anson, it was originally designed for maritime reconnaissance, but was soon rendered obsolete in that role. However, it was rescued from obscurity by its suitability as a multi-engine air crew trainer, becoming the mainstay of the British Commonwealth Air Training Plan. By the end of production in 1952, the Anson spanned nine variants and a total of 8,138 were built in Britain by Avro. From 1941, a further 2,882 were built by Canadian Federal Aircraft Ltd.

Design and development

The Anson was derived from the commercial six-seat 652 and the militarised version, which first flew on 24 March 1935, was built to Air Ministry Specification 18/35. It was the first RAF monoplane with a retractable undercarriage. Avro allotted the type number 652A to the Anson. The first production run resulted in 174 Anson Mk I aircraft for service with Coastal Command. No. 48 Squadron RAF was the first to be equipped in March 1936.

A distinctive feature of the Anson I was its landing gear retraction mechanism which required no less than 140 turns of the hand crank by the pilot. To forgo this laborious process, early model Ansons often made short flights with the landing gear extended at the expense of 30 mph (50 km/h) of cruise speed.[1]

A total of 11,020 Ansons were built by the end of production in 1952, making it the second-most-numerous (after the Vickers Wellington) British multi-engine aircraft of the war.[1]

Operational history

At the start of the Second World War, there were 26 RAF squadrons operating the Anson I: 10 with Coastal Command and 16 with Bomber Command. However, by this time, the Anson was obsolete in the roles of bombing and coastal patrol and was being superseded by the Armstrong Whitworth Whitley and Lockheed Hudson.

Limited numbers of Ansons continued to serve in operational roles such as coastal patrols and air/sea rescue. Early in the war, an Anson scored a probable hit on a German U-boat. In June 1940, a flight of three Ansons was attacked by nine Luftwaffe Messerschmitt Bf 109s. Remarkably, the Ansons downed two German aircraft 'and damaging a third before the 'dogfight' ended',[2] without losing any of their own.[1] The aircraft's true role, however, was to train pilots for flying multi-engine bombers such as the Avro Lancaster. The Anson was also used to train the other members of a bomber's air crew, such as navigators, wireless operators, bomb aimers and air gunners. Postwar, the Anson continued in the training role and light transport roles. The last Ansons were withdrawn from RAF service with communications units on 28 June 1968.

The Royal Australian Air Force operated 1,028 Ansons, mainly Mk Is, until 1955. The Royal Canadian Air Force and Royal Canadian Navy operated Ansons until 1952. The USAAF employed 50 Canadian-built Ansons, designated as the AT-20. The Royal New Zealand Air Force operated 23 Ansons as navigation trainers in the Second World War, (alongside the more numerous Airspeed Oxford), and acquired more Ansons as communication aircraft immediately after the war. A preserved navigation trainer is in the Royal New Zealand Air Force Museum at Wigram.

The Egyptian Air Force operated Ansons in communications and VIP duties. A specially outfitted Anson was gifted to the then King by the Royal Air Force. The Royal Afghan Air Force obtained 13 Anson 18 aircraft for various duties from 1948. These aircraft survived through 1972.

Postwar civil use

After the war, Ansons continued in production by Avro at Woodford for civilian use as light transports by small charter airlines and as executive aircraft for industrial and other companies. Countries which saw civilian operations with Ansons included Great Britain, Canada, Australia and Denmark.

Railway Air Services operated Ansons on scheduled services from London's Croydon Airport via Manchester to Belfast (Nutts Corner) during 1946-1947. Sivewright Airways operated three Avro XIX aircraft from their Manchester Airport base on charter flights as far as Johannesburg and on scheduled flights to Ronaldsway Airport in the Isle of Man until 1951. Finglands Airways operated an ex-RAF Anson I on inclusive tour flights and on scheduled flights from Manchester Airport to Newquay Airport between 1949 and 1952.

India ordered twelve new Anson 18Cs in 1948 for use by the Directorate of Civil Aviation as trainers and communications aircraft, and these were delivered from Woodford in spring 1949.

Ansons continued to be built by Avro at Woodford for the RAF until March 1952 and were used as trainers and served in the role of Station communications aircraft until 1968.

Accidents and incidents

On 29 September 1940, Avro Ansons L9162 and N4876 of No. 2 Service Flying Training School RAAF collided in mid-air and became locked together in flight. A successful emergency landing was made at Brocklesby, New South Wales. L9162 became a ground instructional airframe, whilst N4876 was repaired and returned to service.

On 19 December 1945, a Companhia Meridional de Transportes Avro Anson Mk. II registration PP-MTA crashed in the neighborhood of Itaipu, Niterói, Brazil killing all passengers and crew, including the pilot and owner of the airline, Álvaro Araújo.[3]

On 11 June 1948, Avro XIX G-AGNI of Lancashire Aircraft Corporation ditched off Bradda Head, Isle of Man due to fuel exhaustion. The aircraft was operating a scheduled passenger flight from Squires Gate Airport, Blackpool to Ronaldsway Airport, Isle of Man via RAF Walney Island, Lancashire. All nine people on board were rescued by a trawler from Port Erin and the MV Silkthorn.[4]

A memorial at the church in Windrush village, Gloucestershire, describes Sgt Pilot Bruce Hancock RAFVR who died on 18 August 1940 when downing a German Heinkel bomber by ramming it with his unarmed training Avro Anson aircraft flying from RAF Windrush.

Variants

The main Anson variant was the Mk I, of which 6,704 were built in Britain. The other variants were mainly distinguished by their powerplant with Canadian-built Ansons using local engines. To overcome steel shortages, the 1,051 Canadian-built Mk V Ansons featured a plywood fuselage.
