British Aerospace 125

File:De Havilland DH125 62.jpg

In 1961, de Havilland began work upon a small business jet, then known as the DH.125 Jet Dragon, which was intended to replace the piston engined de Havilland Dove, a successful business aircraft and light transport. Prior to the start of the project, de Havilland had determined that a successful business jet would require several variables to be met, including a range of at least {{convert|1,000|mi|km}}, the speed and cost factors of a suitable jet engine to outperform turboprop-propelled competitors, and an engineering philosophy that favoured reliability and conventionality. The design team settled on a twin-engine aircraft with the engines mounted on the rear fuselage. The Bristol Siddeley Viper turbojet powerplant was selected to power the type.Flight 1962, p. 896.

On 13 August 1962, the first of two prototypes conducted its first flight, a second aircraft followed it on 12 December that year.Jackson 1987, pp. 506–507. The second prototype was more aerodynamically representative of a production aircraft, and was fitted out with more equipment than the first prototype; the subsequent production-standard aircraft incorporated several changes and improvements from the prototypes, such as a longer fuselage and a greater wingspan.Flight 1962, p. 899. The first production-standard aircraft performed its first flight on 12 February 1963. The first delivery to a customer took place on 10 September 1964.Jackson 1973, p. 277.Taylor 1965, pp. 148–149.

The aircraft went through many designation changes during its service life. Hawker Siddeley had bought de Havilland the year before the project had started, but the legacy brand and "DH" designation was used throughout development. After the jet achieved full production, the name was changed to "HS.125" except for American exports which retained the DH.125 until it was replaced by BH.125 for Beechcraft-Hawker. When Hawker Siddeley Aircraft merged with the British Aircraft Corporation to form British Aerospace in 1977, the name changed to BAe 125. When British Aerospace sold its Business Jets Division to Raytheon in 1993, the then-main variant of the jet became widely referred to as the Hawker 1000.George, Fred. [http://d16bsf97ryvc45.cloudfront.net/Media/2013/01/hawker_1000.pdf "Update: The Improved Hawker 1000."] Pilot Report, March 1995. 3300. pp. 1–7.

While the two prototypes were assembled at de Havilland's Hatfield site, final assembly of all production aircraft would take place at the Broughton factory near Chester until the 1990s.Flight 1962, p. 902. By the 2000s, the fuselage, wings and tailfin of the aircraft were still being assembled and partially equipped in the Broughton site, now being owned and managed by Airbus UK; various sub-assemblies were also produced in Airbus UK's Buckley facility. From 1996 onwards, the assembled sections and components were shipped to Wichita, Kansas in the United States, to undergo final assembly. Writing in 1993, Flying Magazine said of the type "In numerical terms, the 125 series is the most successful British commercial aircraft ever built, and the world's longest in-production business jet".

Production of the aircraft came to an abrupt halt in 2013 due to the bankruptcy of owner Hawker Beechcraft, who has suffered during the Great Recession of the late 2000s in which demand for business jets had slumped for a number of years. The type had been in production for more than 50 years when manufacturing stopped, during which time over 1,600 aircraft had been produced. In April 2013, the type certificate and support responsibility for all 125s built was transferred to the reformed Beechcraft Corporation.Federal Aviation Authority Type Certificate Data Sheet A3EU. As of October 2012, Beechcraft does not intend to restart production of its business jet lines; instead the company intends to alternatively sell or dismantle the production facilities for the 125 family.Warwick, Graham.

The BAe 125 is a low-winged monoplane, powered by two engines mounted on the rear fuselage. It features a slightly swept wing, which is based on the larger de Havilland Comet wing planform, and uses large slotted flaps and airbrakes for operating from small airfields; the aircraft can be flown from hardened grass airstrips. The aircraft has a cylindrical fuselage with a one-piece wing mounted on the underside of the fuselage; most of the manufacturing and assembly work on the wing and fuselage is able to be done with them as separate items with the two being joined late in the production process.Flight 1962, pp. 897, 902. The wing has integral fuel tanks which contain most of the fuel.Flight 1962, p. 898.

Early models of the aircraft were powered by several versions of the Bristol Siddeley Viper turbojet engine, while later aircraft have adopted more recent turbofan powerplants such as the Garrett TFE731 and Pratt & Whitney Canada PW300.Goold, Ian. [http://www.flightglobal.com/pdfarchive/view/1991/1991%20-%201380.html "Corporate Aircraft Usage Survey."] Flight International, 4 June 1991. p. 52.Winn 1989, p. 33. Both engines drive an electrical generator and hydraulic pump which supply power to the aircraft systems so in the event of a single engine failure, all aircraft systems continue to operate normally.

All control surfaces of the aircraft are aerodynamically balanced using set-back hinges and geared tabs. The flaps and airbrakes are operated hydraulically, while the ailerons, elevators, and rudder are manually operated. The design of the control circuits allows for a Collins-built A.P.103 autopilot to be incorporated. The aircraft is equipped with a de-icing system, which uses a mixture of bleed air from the engines, TKS fluid for general airframe, and AC electric windshield heating to prevent ice formation. Weather radar was incorporated into the aircraft's avionics. The Royal Air Force equipped some of their aircraft with equipment to defend against attack by infra-red missiles.

The pressurised fuselage was designed to accommodate two pilots and six passengers. Various interiors were offered, with a high degree of passenger comfort. In an executive configuration, the flight deck is separated from the main passenger cabin; the single entrance of the aircraft, located directly behind the cockpit and forward of the passenger cabin, forms a vestibule area in which luggage can be stored and meals prepared during flight. An unobstructed cabin floor with {{convert|5|ft|9|in|m}} of headroom and a {{convert|3|ft}} wide cabin door also allowed the loading of bulky equipment, which was seen as particularly attractive to military operators. However, the internal "up and over" door was replaced on the Series 400 and thereafter by a more usual outward opening door with built-in steps. An emergency overwing exit hatch is located in the passenger cabin midsection over the starboard wing (although some versions have both port and starboard exits). The rear of the fuselage has a large equipment bay and, on some aircraft, one or two additional fuel tanks for extended operations.

Having entered service as one of the first-generation executive jets, the British Aerospace 125 has been operated by a wide variety of customers, ranging from government and military operators to private customers and businesses, it has also seen use by several airlines. Many of the aircraft's customers have been located in North America; in 1990, out of the 650 aircraft then being operated, more than 400 were being flown in the United States. Reportedly, one aircraft was being sold every seven working days for a substantial period of the type's production life.Winn 1989, p. 32. Successively larger versions were introduced to extend the type's appeal and to better compete against larger jets being used for business travel, such as the Gulfstream IV and Falcon 900.

The Royal Air Force was a significant early operator of the type, receiving 20 aircraft equipped as a navigation trainer and designated Hawker Siddeley Dominie T.1. The type entered service in 1965, with the surviving aircraft upgraded in 1996 to be more suitable for training crews for modern aircraft, with a new radar fitted.Winchester Air International October 2008, pp. 55–56. The Dominie served in excess of 45 years before being retired in 2011 due to diminishing requirements.Norton, Phillip. [https://www.bbc.co.uk/news/uk-england-lincolnshire-12237425 "Farewell flypast for RAF's Hawker Siddeley."] BBC News, 20 January 2011. Additional 125s were acquired and operated by No. 32 Squadron RAF as communications and light transport aircraft; these were also occasionally operated to transport Queen Elizabeth II and other members of the British Royal Family.[http://www.raf.mod.uk/equipment/bae125.cfm "BAe 125."] {{Webarchive|url=https://web.archive.org/web/20090430160433/http://www.raf.mod.uk/equipment/bae125.cfm |date=30 April 2009 }} Royal Air Force, Retrieved: 14 June 2014. In the later stages of the War in Afghanistan, various 125s were used to transport military officers and other key personnel in and out of the country. The type was scheduled to be withdrawn from RAF service by 2022, but was withdrawn in 2015.Hoyle, Craig. [http://www.flightglobal.com/news/articles/raf-faces-tough-choices-over-future-air-transport-fleet-346672 "RAF faces tough choices over future air transport fleet"] Flight International, 31 August 2010.

By the early 1990s, British Aerospace, the manufacturer of the type at this point, had two main variants of the aircraft in production; the smaller 125-800 and larger 125–1000. The 125–1000, which conducted its first flight on 16 June 1990, had several changes to give the type a reported intercontinental range, including the adoption of the newly developed Pratt & Whitney Canada PW300 engine and new digital avionics, such as FADEC.[https://books.google.com/books?id=OaWFVVcBXaEC&pg=PA30 "BAE 1000 Makes First Hop"] Flying Magazine, September 1990. 117, (9). p. 28.[http://jetav.com/hawker-beechcraft-1000-specs-and-description/ "Hawker Beechcraft 1000 Specs and Description."] Premier Jet Aviation, Retrieved: 22 June 2014. Following Raytheon's purchase of British Aerospace's Business Jet Division during the 1990s, the two in-production variants were re-designated as the Hawker 800 and Hawker 1000 respectively.

The 125 is the only business jet to have been hijacked: in 1967, a chartered 125 carrying the former Congolese Prime Minister Moise Tshombe was diverted to Algeria by armed persons on board. The 125 is also likely to be the only business aircraft to survive being hit by an air-to-air missile: in August 1988, a British Aerospace 125-800 transporting Botswana President Quett Masire was struck by a missile launched by a nearby Angolan Mig-23, apparently inadvertently.{{Cite web|url=https://aviation-safety.net/database/record.php?id=19880807-0|title=ASN Aircraft accident British Aerospace BAe-125-800A OK-1 Cutio Bie|first=Harro|last=Ranter|website=aviation-safety.net}}{{Cite web|url=https://apnews.com/article/b20ba6a8d1d775d8bfa185df16e22c7d|title=Botswana Says Angolan Jet Shot Down President's Plane|website=AP NEWS}} While badly damaged by the direct hit (which resulted in the loss of an engine, decompression of the cabin, and rupture of its fuel tanks) the aircraft was successfully landed by BAe demonstrator pilot Arthur Ricketts. It was later rebuilt.

In 2013, the FAA modified its rules to prohibit the operation of jets weighing {{convert|75000|lb}} or less that are not stage 3 noise compliant, specifically mentioning the 125 series of aircraft. This required any aircraft of the type either to have compliant engines installed, or to be fitted with a hush kit, to fly over most of the United States after 31 December 2015.[http://www.gpo.gov/fdsys/granule/FR-2013-07-02/2013-15843/content-detail.html "78 FR 39576 – Adoption of Statutory Prohibition on the Operation of Jets Weighing 75,000 Pounds or Less That Are Not Stage 3 Noise Compliant."] Federal Register, 78(127), 2 July 2013.
