Development

The Avro 539 (later 539A) was a single-seat floatplane first flown on 29 August 1919. It was single bay, unstaggered biplane with a nose-mounted 240hp (179kW) Siddeley Puma piston engine and twin wooden floats. It had a single open cockpit for the pilot aft of the wings. Registered "G-EALG" it was modified before the race with a balanced rudder and elongated fin. The Schneider Trophy was held on the 10 September 1919 but the 539 was eliminated. It was later modified as a landplane with a smaller fin and flown at an Aerial Derby at Hendon Aerodrome in July 1920. The aircraft forced landed but was re-built as the Avro 539B for the 1921 Aerial Derby with a 450hp (336kW) Napier Lion and a revised landing gear and registered "G-EAXM". It was destroyed in a landing accident at Hamble on 15 July 1921 on the eve of the race.
