History Hawker Siddeley Aircraft
Hawker Siddeley HS 748 (formerly Avro HS 748)
Manufactured 1961–1988, First flight 24 June 1960
The HS 748 was developed during the late 1950s as a move to re-orient the company towards the civil and export markets. Powered by the popular Rolls-Royce Dart turboprop engine, it was specifically designed as a modern feederliner to act as a replacement for the aging Douglas DC-3s then in widespread service. Originally intended to seat a smaller number of passengers, market research indicated that a seating capacity of around 40 passengers would be optimal for the type. As a means to differentiate the new airliner from competitors, it was designed to possess a high level of performance, including its short takeoff and landing (STOL) capabilities and overall ruggedness. First flying on 24 June 1960, the series 1 HS 748 entered revenue service in 1961.
Into flight
On 24 June 1960, the first Avro 748 made its maiden flight from the company's Woodford, Cheshire, aircraft factory.[3] Flight testing of the two prototypes quickly validated the type's short-field performance. Eighteen Avro 748 Series 1 aircraft were produced; during April 1962, the first production aircraft were delivered to launch customer Skyways Coach-Air Limited. However, the majority of the series 1 were export sales to operator Aerolíneas Argentinas.[citation needed] During the early 1960s, Avro's individual identity within the Hawker Siddeley Group was expunged, after which the airliner was marketed by the parent company as the HS 748.
After the initial batch of series 1 aircraft was completed, production transitioned to the improved series 2. The series 2 was largely similar to its predecessor, principally benefiting from the adoption of more powerful Dart RDa 7 Mk 531 engines and an increased gross weight. According to aviation periodical Flight International, during 1960, the basic price for a new Avro 748 Series 1 was £176,000, while that of the corresponding Avro 748 Series 2 was reportedly £196,000
Variants
- 748 Series 1 – The original Avro 748 twin-engined short / medium-range airliner, powered by two Rolls-Royce Dart RDa 7 Mk 514 turboprop engines. 24 built.[3]
- 748 Series 2 – The Series 2 entered production in 1961 with a higher take-off weight and Mk 531 engines. 111 built.
- 748 Series 2A – Introduced in 1967, with a further increase in take-off weight and Mk 532 or 534 engines. 157 built, making the 748 one of the more successful British airliners and the 2A the most popular variant.
- 748 Series 2B – The main production model after Hawker-Siddeley was absorbed by British Aerospace, the 2B featured a 4-foot increase in wingspan, increased gross weight, Mk 536 engines, a modernized cabin, and systems improvements. 28 built.

The Hawker Siddeley HS 748 (formerly Avro HS 748) is a medium-sized turboprop airliner originally designed and initially produced by the British aircraft manufacturer Avro. It was the last aircraft to be developed by Avro prior to its absorption into Hawker Siddeley.

Another supportive feature of the 748 was a design decision to adopt straightforward systems and use proven components where realistically possible.

During 1976, Eric Johnson, sales engineering manager of Hawker Siddeley Manchester, stated that the company was studying options for equipping a model of the HS 748 with turbofan engines.
