The Avro 558 was a British single-engined ultralight biplane built by Avro at Hamble Aerodrome.


Design and development

The Avro 558 was designed for the 1923 light aircraft 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 500 cc Douglas engine). The first aircraft was modified with a 698 cc (42.6 in³) Blackburne Tomtit and both had modifications to the landing gear.

Operational history

The aircraft did not win the competition, but the second aircraft went on to establish a world record for its class of aircraft of 13,850 ft (4,220 m) over Lympne on 13 October 1923 [1]. It is not known what happened to the two aircraft, they have not been reported since 1923.
