The Avro 627 Mailplane was a British single-engine biplane that Avro developed in 1931 from the Avro Antelope light bomber for carrying mail in Canada. Roy Chadwick redesigned the incomplete prototype of a proposed fighter, which had become the Avro 622, after Canadian Airways showed interest in a mail plane. It had a single bay of wings, a 525 hp Armstrong Siddeley Panther engine and could be fitted for wheels or floats. The sole prototype, G-ABJM, was certificated on 2 August 1931 and shipped to Canada for trials, but the Canadian government cut its civil aviation subsidy and the aircraft returned to England. It recorded the fastest speed in the 1932 King's Cup Race, was converted in 1933 into the Avro 654 test bed for the Armstrong Siddeley Tiger engine, and was dismantled at Woodford in 1934.
