TheAvro Avianis a series ofBritishlight aircraft designed and built byAvroin the 1920s and 1930s. While the various versions of the Avian were sound aircraft, they were comprehensively outsold by thede Havilland Mothand its descendants.
Design and development
[edit]The Avro 581 Avian prototype was designed and built to compete in theLympne light aircraft trialsatLympne Aerodromein September 1926. Its wooden fuselage was based on that of the Avro 576autogyro,but it was fitted with conventional biplane wings and powered by a 70 hp (50 kW)Armstrong Siddeley Genetengine.[1]It performed well at the trials, but was eliminated due to engine failure.

In early 1927 it was re-engined with an 85 hp (63 kW)ADC Cirrusengine as the Type 581A and sold toBert Hinkler.
Production aircraft were designated Type 594 and were built in a number of versions, mainly powered by Cirrus engines.[2]A version with a welded steel tube fuselage was produced in 1929 as the Avro 616 Avian IVM to meet overseas requirements for an easier-to-repair structure.[3]This version was built in the largest numbers, with approximately 190 built.[4]
The Avian was also produced under licence in Canada, byOttawa Car Manufacturing CompanyinOttawa,Ontario.[5]
Operational history
[edit]While outsold by thede Havilland Mothand its derivatives—which first flew more than a year earlier than the Avian—the Avian was used extensively as a civil tourer or trainer, with many being sold overseas. Avians were assembled by the Whittesley Manufacturing Co.,Bridgeport, Connecticut,USA, and the Ottawa Car Manufacturing Company, Canada,[6]as well as by Avro itself.[7]
After further modifications to wings and undercarriage as the Avro 581E, Hinkler used this aircraft for a series of long-distance flights, culminating in a 15½-day solo flight fromCroydon,UKtoDarwin,Australia.[8]In 1998 Lang Kidby recreated this flight in a 1927 Type 594 Avian VH-UFZ (ex G-AUFZ)
Avro Avian 594 Avian III (SN R3/AV/101) was owned by Lady Mary Heath andAmelia Earhart.Earhart's Avian had an 84 hp (63 kW) Cirrus Mk II engine. It was originally registered to Lady Heath on 29 October 1927 and given the UK aircraft markingG-EBUG.When Earhart brought it to the United States it was assigned "unlicensed aircraft identification mark"7083;aircraft not officially certificated in the United States were allowed to be flown as unlicensed but identified aircraft. Avian7083was used on Earhart's first long solo flight, which occurred just as Amelia was coming into the national spotlight. By making the trip in August 1928, she became the first woman to fly solo across the North American continent and back. In 2001 Carlene Mendita recreated this flight in Greg Herrick's Type 594 Avian which he had purchased from Lang Kidby. At the time Herrick purchased the Avian from Kidby, two years prior, it was the oldest flying aircraft in Australia. It is now based in Minneapolis, Minnesota.
Wilfrid R. "Wop" Mayused a 594 to make his January 1929 mercy flight withdiphtheriaantitoxin fromEdmontontoFort Vermilion,Alberta.[9]

An Avian (Red Rose) was used byBill Lancasteron a successful long distance flight to Australia, and another (Southern Cross Minor) on his final record attempt to South Africa in 1933.
In July 1930,Winifred Brownwon theKing's Cup Raceflying Cirrus III Avian.[10]One Avian, piloted by Sydney Thorn, took part in theChallenge International de Tourisme 1930with moderate success (16th place).
On 7 January 1931,Guy Menziesflew an Avian, theSouthern Cross Junior,fromAustraliatoNew Zealand.He was the first person to fly solo across theTasman Sea.
A single Genet-powered Avian II was bought by theRoyal Air Force,while Avians were also bought by theSouth African Air Force,theChinese Naval Air Service,theEstonian Air Forceand theRoyal Canadian Air Force.
AviatorBeryl Markhamused an Avian extensively in East Africa in the 1930s.[11]
