The Auster J/1 Autocrat was a 1940s British single-engined three-seat high-wing touring monoplane built by Auster Aircraft Limited at Rearsby, Leicestershire.

History[edit]

As the end of the Second World War approached the designers at Taylorcraft decided to develop a tourer version of the robust and reliable Taylorcraft Auster Model J AOP.V observation aircraft series. An Auster 5, registered G-AGOH, was modified to take a 100 hp (75 kW) Blackburn Cirrus II engine for trials. At the same time a prototype aircraft was built designated the Taylorcraft Auster V Series J/1 Autocrat. The long name was not used as the company changed name to Auster Aircraft Limited and the aircraft became known as the Auster J/1 Autocrat.[1]

The designation J/1 derived from the progenitor Model J, which was the Auster AOP.V.[2][3]

Production and operation[edit]

The first production aircraft, registered G-AGTO, was delivered in December 1945. One of the more spectacular feats of the type was the first visit of a civilian aircraft to an aircraft carrier, HMS Illustrious in the English Channel in October 1946.[citation needed] The last Rearsby built J/1s were delivered in 1952.

The Autocrat became one of the most successful post-war British light aircraft with more than 400 built. A small number of variants were built and the aircraft became the basis for a family of light aircraft. The Autocrat was used by individual pilots, aero clubs and by small charter firms for passenger flights, banner towing and photography.

Many J/1s were converted to J/1N Alpha standard with a higher fin and fitted with a 130 h.p. Gipsy Major engine, as used in the J/1B Aiglet. 45 new build J/1N Alphas were completed in 1956/57, mainly for export to Australia.

A single Autocrat G-AGVI was converted by V.H.Bellamy in 1965 to be powered by a Rover TP gas turbine engine. It reverted to normal power in 1968.

Starting in 1946, newly built examples of the Autocrat and Alpha were exported direct from the production line at Rearsby to many countries worldwide including Argentina, Australia, Belgium, Brazil, Ceylon, Denmark, Egypt, France, Iraq, Jordan, Netherlands, New Zealand, Norway, Pakistan, South Africa, Southern Rhodesia, Sweden, Switzerland, Trinidad and Tobago, Uganda and Uruguay.[1] Other UK-registered aircraft were later sold overseas on the secondhand market.

Numbers of Autocrats and Alphas continue to fly (2014) with private owners in the United Kingdom, Australia, New Zealand and elsewhere.
