The Auster J/5 Autocar is a late 1940s British single-engined four-seat high-wing touring monoplane built by Auster Aircraft Limited at Rearsby, Leicestershire.

Design and production

The company recognised a need for a four-seat touring aircraft to complement the three-seat Auster J/1 Autocrat. The J/5 Autocar looked similar to the Autocrat, but was a new model featuring wing-root fuel tanks and an enlarged cabin.

The designation of J/5 for the Autocar followed on from its progenitor, the wartime Model J, which was designated the Auster AOP.V by the Royal Air Force. Postwar models derived from the Model J commenced with the J/1 Autocrat - note the use of J/1, not J-1. The prototype Autocar G-AJYK, a model J/5B, first flew in August 1949 and was exhibited at the Farnborough Air Show in September. A demand for a more powerful version for the tropics produced in 1950 the J/5E powered by a 155hp (116kW) Blackburn Cirrus Major engine. This was further developed as the J/5G which was first flown in 1951 and is also referred to as the Cirrus Autocar. The later J/5P reverted to a more powerful de Havilland Gipsy Major engine. Other variants were built as one-off development aircraft, and some were converted in Australia with more modern engines.

Operations

Saunders-Roe of Cowes, Isle of Wight, acquired a J/5G Autocar and fitted it with an experimental hydro-ski undercarriage and emergency under-wing floats. With this equipment, the aircraft could remain almost stationary on the water.

The majority of the production Autocars were exported to sixteen countries and later resold in five further territories. The Autocar has been primarily operated by private pilot owners and by aero clubs but some were used by small charter firms in the UK and elsewhere as taxi and photographic aircraft. Pest Control Ltd took delivery of five J/5G Autocars in 1952 for crop spraying operations in Sudan.
