The Bristol Taxiplane and Bristol Primary Trainer were light, single-engine biplanes manufactured by the Bristol Aeroplane Company in the early 1920s. A total of 28 units were produced, primarily serving as training aircraft.

Design and development

In 1922, the Bristol Aeroplane Company introduced two closely related light aircraft models powered by the three-cylinder Bristol Lucifer radial engine: the Type 73 Taxiplane—a three-seat utility and touring aircraft—and the Type 83 Primary Trainer, designed as a two-seat trainer for initial pilot instruction at Reserve Flying Schools.

The Taxiplane featured a wooden frame covered with fabric and was equipped with single-bay biplane wings. It accommodated two passengers sitting side-by-side in a cockpit located behind the pilot. The first Taxiplane, registered as G-EBEW, completed its maiden flight on 13 February 1923; however, it was only certified to carry two occupants due to being overweight when fully loaded with a pilot and two passengers. Production was limited to just three units.

The Primary Trainer, also referred to as the Bristol Lucifer, shared the same wing structure, tail assembly, and landing gear as the Taxiplane but incorporated a newly designed narrower fuselage featuring two cockpits arranged in tandem. Thanks to its reduced fuselage width and lighter weight, the Primary Trainer demonstrated improved performance and achieved greater success with 24 aircraft built.

Additionally, a variant known as the Bristol Type 83E was constructed to serve as a test platform for the five-cylinder Bristol Titan radial engine.

Operational history

The initial six Primary Trainers were delivered to the Reserve Flying School at Filton in July 1923 and remained operational there until December 1931, when they were superseded by de Havilland Moth aircraft. One surviving example was converted into a three-seater for sightseeing purposes before being dismantled in December 1933.

The remaining Type 83 aircraft were produced for export markets: twelve units were sold to Chile, five to Hungary, and one to Bulgaria, all transactions occurring in 1926.

Variants
