Hawker Siddeley HS748

The Hawker Siddeley HS748 is a medium-sized turboprop airliner originally designed by the British firm Avro in the late 1950s as a replacement for the aging DC-3s then in widespread service as feederliners. Avro concentrated on performance, notably for STOL operations, and found a dedicated market. 380 aircraft were built by Hawker Siddeley. A larger, stretched development of the HS748, the BAe ATP, attempted to compete with the de Havilland Canada Dash-8 but saw a limited production run.
