Avro 552

The Avro 552 was a British light aircraft produced in the early 1920s. It was another attempt by Avro to sell a derivative of the wartime Avro 504 into the civil market.

In this case, the company took advantage of the large number of war-surplus Wolseley Viper engines left over from Royal Aircraft Factory S.E.5a production. In 1921, one of these was married to a standard 504K airframe for evaluation under the designation Avro 551. Trials proved encouraging, but an extra fuel tank was installed in the upper wing as a result of the higher rate of fuel consumption from the Viper engine, and changes were made to the aileron design as well. 

This configuration went into production as the 552, with the Argentine Navy purchasing 13 examples of a float-equipped version, the 552A, which served as trainers until 1927. Two similar machines were purchased by Bulgaria. 

In 1924, the Royal Canadian Air Force arranged for Canadian Vickers to purchase a licence to produce five landplane and nine seaplane examples for use in forestry patrol. These differed from British-built aircraft by the use of U.S. Naval Aircraft Factory floats, and increased fuel tankage for extended range.
