The Beagle A.113 Husky (originally, the Auster D.5) was a three-seat British light aircraft built in the 1960s, a development of the Auster Alpha. It first flew as an Auster design in January 1960, but that company was taken over by Beagle Aircraft in September. It was initially available with a 160 hp Lycoming O-320 engine and 133 examples (Auster D.5/160) were built by the Oficinas Gerais de Material Aeronáutico in Portugal from 1961 onwards; and the Portuguese Air Museum preserves two of these; one in flying condition. Subsequently, Beagle developed the D5/160 as the "Beagle D5/180 Husky" with a 180 hp Lycoming O-360 engine, the first being G-ASBV first flown in 1962. A small number were sold until production was discontinued in 1967.
The designation "A.113" was only a design number and was not used in promotional material or in aircraft registrations with the Civil Aviation Authority where the term 'D5/180' was preferred. Additionally, the name Husky was only given to this version and not to the D5/160.
