[edit] Development
The Avro 636 was designed in November 1934 by Roy Chadwick, Avro's chief designer as a one or two seat fighter trainer, and was planned to reproduce the flying characteristics of single-seat fighters. It had a similar structure to the Avro Tutor, with a welded steel tube fuselage[1].
The aircraft was designed to be operated as a single or two seater, with the provision for fitting two forward firing Vickers machine guns.
[edit] Operational history
Four Avro 636s were ordered by the Irish Air Corps in December 1934. These aircraft were powered by old Armstrong Siddeley Jaguar IVC engines, which had originally been purchased by the Irish in 1930 for use in Vickers Vespa army co-operation aircraft. Although the Jaguar IVC powered aircraft was planned to be designated as the Avro 667, they were always referred to as Avro 636s [1].
The four aircraft were delivered in August 1935, and remained in service for several years.
