In 1922, the
Bristol Aeroplane Company developed a pair of related light aircraft designs, powered by theBristol Lucifer three-cylinderradial engine , the Type 73 Taxiplane, a three-seat light utility aircraft and tourer, and the Type 83 Primary Trainer, a two-seat trainer intended for use for primary training at Reserve Flying Schools Cite book |author=Barnes, C.H.|title=Bristol Aircraft Since 1910 |Edition =First Edition |publisher=Putnam |location= London|year=1964 .The Taxiplane was of wooden construction with fabric covering, and was fitted with single bay
biplane wings. It carried two passengers side-by-side in acockpit behind the pilot. The first Taxiplane, registered "G-EBEW", flew on13 February 1923 , but could only be certificated as a two-seater, being overweight with two passengers and a pilot. Only two more Taxiplanes were built cite book |last= Jackson|first= A.J.|authorlink= |coauthors= |title= British Civil Aircraft since 1919 Volume 1|year= 1974|publisher= Putnam|location= London|isbn=0 370 10006 9 ] . The Primary Trainer, also known as the Bristol Lucifer used the same wings, tail andundercarriage as the Taxiplane, but with a new narrowerfuselage containing two tandem cockpits. The Primary Trainer showed better performance owing to its slimmer fuselage and lower weight, and was more successful, 24 being built.A further aircraft, the Bristol Type 83E, was built as a testbed for development of the five-cylinder
Bristol Titan radial engine.Operational history
The first six Primary Trainers entered service with the Reserve Flying School at Filton in July 1923, continuing in service until December 1931, when they were replaced by
de Havilland Moth s. One of the surviving aircraft was modified as a three-seater and was used for sightseeing. It was scrapped in December 1933.The remainder of the Type 83s were produced for export, with twelve being sold to
Chile , five toHungary and one toBulgaria , all in 1926.Variants
