The Avro 652 was a British light civil airliner of the 1930s built by A.V. Roe and Company Limited. It was a twin-engine, low-wing monoplane with a retractable undercarriage, and a tailwheel. Although only two were produced, it formed the basis for the successful Avro Anson.

[edit] Development
Imperial Airways issued a specification to Avro in 1933 for a light airliner to transport four passengers for up to 420 miles at a cruising speed of 130 mph. By August, Roy Chadwick's team had produced a design study. This had to be revised when Imperial changed the specification to enable the machine to fly the Karachi-Bombay-Colombo night mail service but the amended design was accepted and an order for two aircraft was issued in April 1934. The first aircraft flew on 7 January 1935 and the type was certificated in March of that year. [1]
[edit] Operational history
The aircraft were delivered to Imperial Airways at Croydon on 11 March. They served with Imperial until 1938, when they were sold to Air Service Training Ltd.
After the outbreak of war, both 652s were impressed by the Air Ministry for service with the RAF but both were transferred directly to the Fleet Air Arm in 1941 and served with 811 Squadron until struck off in March 1942.[2]
