It was developed shortly after the Second World War and sold in large numbers during the immediate post-war years, being typically employed as a replacement for the de Havilland Tiger Moth biplane. The Chipmunk was the first postwar aviation project conducted by de Havilland Canada. It performed its maiden flight on 22 May 1946 and was introduced to operational service that same year. During the late 1940s and 1950s, the Chipmunk was procured in large numbers by military air services such as the Royal Canadian Air Force (RCAF), Royal Air Force (RAF), and several other nations' air forces, where it was often utilised as their standard primary trainer aircraft. The type produced under licence by de Havilland in the United Kingdom, who would produce the vast majority of Chipmunks, as well as by OGMA (Oficinas Gerais de Material Aeronáutico) in Portugal. The type was slowly phased out of service beginning in the late 1950s, although in the ab initio elementary training role, this did not happen in the Royal Air Force until 1996, when it was replaced by the Scottish Aviation Bulldog. Many Chipmunks that had been in military use were sold to civilians, either to private owners or to companies, where they were typically used for a variety of purposes, often involving the type's excellent flying characteristics and its capability for aerobatic manoeuvres. More than 70 years after the type having first entered service, hundreds of Chipmunks remain airworthy and are in operation around the world. The Portuguese Air Force still operates six Chipmunks, which serve with Esquadra 802, as of 2018. The de Havilland Canada DHC-1 Chipmunk is a two-seat, single-engine aircraft that has been heavily used as a primary trainer aircraft. The basic configuration of the aircraft included a low-mounted wing and a two-place tandem cockpit, which was fitted with a clear perspex canopy covers the pilot/student (front) and instructor/passenger (rear) positions and provided all-round visibility. The Chipmunk uses a conventional tailwheel landing gear arrangement and is fitted with fabric-covered flight control surfaces; the wing is also fabric-covered aft of the spar. In terms of handling, the Chipmunk exhibited a gentle and responsive flight attitude. Early production aircraft were only semi-aerobatic, while later production models were almost all fully aerobatic. For more information, click here.
