Avro 626

The Avro 626 was a single-engined British biplane trainer produced by Avro between the wars, developed from the Model 621 Tutor for export to smaller air forces as one aircraft able to carry out general aircrew training and other roles. It had an additional cockpit behind the rear seat of the Tutor, fitted with a Scarff ring for a machine gun and carrying navigation, wireless and gunnery equipment. Most had a 240 hp Armstrong Siddeley Lynx IVC, though many for Egypt and Brazil used a 260 hp Cheetah V. The prototype first flew in 1930, and 198 Avro 626s and Prefects were produced, with the RAF and RNZAF calling the type the Prefect. The Avro 637 was an armed patrol version.
