Design and development

The Avro 558 was designed for the 1923 "Daily Mail"-sponsored light-aeroplane trials for single-seaters at Lympne Aerodrome. Two Avro 558 biplanes were built, they were biplanes powered by motorcycle engines (one with a B&H twin-cylinder air-cooled engine, the second with a 500cc Douglas engine). The first aircraft was modified with a 698cc Blackburne Tomtit and both had modifications to the landing gear.
