British Aerospace ATP
|West Air Sweden ATP|
|First flight||6 August 1986|
|Developed from||Hawker Siddeley HS 748|
The British Aerospace ATP was an airliner produced by British Aerospace, designed as an evolution of the Hawker Siddeley HS 748. The fuel crisis and increasing worries about aircraft noise led business planners at British Aerospace to believe that there was a market for a short-range, low-noise, fuel-efficient turboprop aircraft. By the time it entered the market, the segment was already well represented by designs such as the de Havilland Canada Dash 8 and ATR 42, and production was ended after only 64 examples.
Design and development 
The airframe of the HS 748 was redesigned with a lengthened 26.01 m body and a 30.62 m wing span. Minor modifications were made to the nose and tail shapes, as well as smaller windows on a shorter pitch. The twin Rolls-Royce Dart engines were replaced with Pratt & Whitney Canada PW126 fuel efficient engines. A custom-designed, slow-turning, six-blade propeller was developed by Hamilton Standard.
The aircraft first flew in August 1986 and entered service with British Midland in 1988. The type has an advanced EFIS Flight Deck, and has a good short-field performance. In addition to these virtues, it is also very quiet upon take off.
In total 64 aircraft were assembled at BAe's Woodford and Prestwick facilities with the manufacture of the airframe and wings undertaken at Chadderton. Production ended at Prestwick in 1996. The plane can accommodate between 64 and 72 passengers depending on the seat configuration. The biggest operators of the aircraft are British Airways CitiExpress and West Air Sweden.
In 2001 the ATP Freighter project allowed six ATPs to be converted into cargo aircraft for West Air Sweden. Using a modification of the HS 748 freight door, the ATPF can carry 30% more cargo than its predecessor with a 10% increase in running costs. The ATPF made its first flight from West Air Sweden's facility in Lidköping on 10 July 2002.
As of November 2011 a total of 40 ATP aircraft remain in airline service with West Air Sweden (12), Atlantic Airlines (12), NextJet Sweden (4), Deraya (2) and Air Go Airlines (1). The only airline operating passenger flights in the ATP is NextJet Sweden.
Several ATP variants were proposed and produced for civil and military use:
- Jetstream 61
The British Aerospace Jetstream 61 was an improved derivative of the ATP. It featured an interior based on the Jetstream 41 with innovative cabin wall armrests and an increase in capacity from 64-70 seats. In addition the airframe incorporated more powerful PW127 engines and increased weights and range.
The first flight was completed by the original prototype ATP (serial number 2001) reregistered G-PLXI (LXI being the Roman numeral for 61) on 10 May 1994. Four airframes were subsequently produced as Jetstream 61’s (2064–2067) before British Aerospace’s regional operations were merged with ATR on 26 January 1995. With the already highly successful ATR72 now part of the same product range the Jetstream 61 was immediately cancelled with all four airframes being scrapped at Woodford.
The original ATP and Jetstream 61 prototype is currently in storage at Woodford awaiting for a final move to the Jetstream Club at Liverpool.
- Maritime ATP
This was a variant for use in military naval operations, with a surveillance radar under the forward fuselage, nose-mounted FLIR and internal sonar buoys. A suite of special crew stations also featured, as did a choice of up to six weapon pylons under the wings and fuselage. The Maritime ATP was later known as the BAe P.132. None were built.
The AEW was a 1986 proposal for an Airborne Early Warning aircraft for Australia, with two EMI Skymaster radars in nose and tail radomes, similar in appearance to the Nimrod AEW.3. None were built.

Notable accidents and incidents involving BAe ATP aircraft 
- On 19 April 1997 Merpati Nusantara Airlines Flight 106 lost control at 2000 feet on approach to Tanjung Pandan-Bulutumbang Airport in Indonesia. 15 people died and 43 survived the crash of Flight 106 the second worst air accident involving British Aerospace ATP aircraft.
- On 11 December 1999 SATA Air Açores Flight 530M crashed into mountain on the Sao Jorge Island, Açores, Portugal on a short haul flight. All 35 passengers and crew on board died in the crash. The accident was the worst air accident involving British Aerospace ATP.
