The Boeing 717 is a twin-engine, single-aisle jet airliner, developed for the 100-seat market. The airliner was designed and marketed by McDonnell Douglas as the MD-95, a third-generation derivative of the DC-9. Capable of seating of up to 117 passengers, the 717 has design range of 2,060 nautical miles (3,820 km). The aircraft is powered by two Rolls-Royce BR715 turbofan engines.

The first order was placed in October 1995; McDonnell Douglas and Boeing merged in 1997 prior to production, and the first planes entered service in 1999 as the Boeing 717. Production ceased in May 2006 after 156 were produced.

Douglas Aircraft developed the DC-9 to be a short-range companion to their larger four engined DC-8 in the early 1960s. The DC-9 was an all-new design, using two rear fuselage-mounted Pratt & Whitney JT8D turbofan engines, a small, highly efficient wing, and a T-tail. The DC-9 first flew in 1965 and entered airline service later that year. When production ended in 1982 a total of 976 DC-9s had been produced.

The McDonnell Douglas MD-80 series was introduced into airline service in 1980. The design was the second generation of the DC-9. It was a lengthened DC-9-50 with a higher maximum take-off weight (MTOW) and higher fuel capacity, as well as next-generation Pratt and Whitney JT8D-200 series engines. Nearly 1,200 MD-80s were delivered from 1980 to 1999.

The MD-90 was developed from the MD-80 series. It was launched in 1989 and first flew in 1993. The MD-90 was longer, and featured a glass cockpit (electronic instrumentation) and more powerful, quieter, fuel efficient IAE V2525-D5 engines, with the option of upgrading that to an IAE V2528 engine. Only 117 MD-90 airliners were built.


The MD-95 traces its history back to 1983 when McDonnell Douglas outlined a study named the DC-9-90. During the early 1980s, as production of the DC-9 family moved away from the smaller Series 30 towards the larger Super 80 (later redesignated MD-80) variants, Douglas proposed a smaller version of the DC-9 to fill the gap left by the DC-9-30. Dubbed the DC-9-90, the aircraft was revealed in February 1983 and was to be some 25 ft 4 in (7.72 m) shorter than what was then the DC-9-81 giving it an overall length of 122 ft 6 in (37.34 m) The aircraft was proposed with a 17,000 lbf (76 kN) thrust version of the JT8D-200 series engine, although the CFM56-3 was also being considered. Sized to seat up to 117 passengers, the DC-9-90 was to be equipped with the DC-9's wing with 2 ft (0.61 m) tip extensions, rather than the more heavily modified increased area of the MD-80. The aircraft had a design range of around 1,500 nmi (2,800 km), with an option to increase to 2,000 nmi (3,700 km), and a gross weight of 112,000 lb (51,000 kg). The DC-9-90 was designed to meet the needs of the newly deregulated air transport industry in the United States, however, the development of the short fuselage MD-80 was postponed as a result of the downturn in business in the recession of the early 1980s. When McDonnell Douglas did develop a smaller version of the MD-80, it simply shrunk the aircraft to create the MD-87, rather than offer a lower thrust lighter aircraft that was more comparable to the DC-9-30. With its relatively high MTOW and powerful engines, the MD-87 essentially became a special mission aircraft and could not compete with the all new 100-seaters that were being developed. Although an excellent aircraft for specialized roles, the MD-87 has not really sold on its own, and tends to rely heavily on its commonality factor which has generally limited sales to existing MD-80 operators.

During early 1991, McDonnell Douglas revealed that it was again considering the development of a specialized 100-seat version of the MD-80 family, which was initially dubbed the MD-87-105 (105 seats). The new lighter aircraft was to be some 8 ft (2.4 m) shorter than the MD-87, and would be powered by engines in the 16,000–17,000 lbf (71–76 kN) thrust class.

McDonnell Douglas, Pratt & Whitney, and the China National Aero-Technology Import Export Agency signed a memorandum of understanding to develop a 105-seat version of the MD-80. Then at the 1991 Paris Airshow, McDonnell Douglas announced the development of the new 105-seat version, now designated MD-95. The "MD-95" name was selected to reflect the anticipated year deliveries would begin. McDonnell Douglas first offered the airliner for sale in 1994. With an overall length of 122 ft 5 in (37.31 m), and a maximum takeoff weight (MTOW) of 118,400 lb (53,700 kg), what McDonnell Douglas was proposing at that stage was very similar to the DC-9-90 design of 1983.

In early 1994, the MD-95 re-emerged as quite similar to the DC-9-30. Indeed the aircraft's specification in terms of weight, dimensions, and fuel capacity are almost identical. The major changes included a fuselage "shrink" back to 119 ft 4 in (36.37 m) length (same as the DC-9-30), and the reversion to the original DC-9 wing of 93 ft 5 in (28.47 m) span. At the time of the redefinition, McDonnell Douglas said that it expected the MD-95 to grow into a family of aircraft with the capability of increased range and seating capacity.

The MD-95 was developed to satisfy the market need to replace early DC-9 models, then approaching 30 years old. The MD-95 project was a complete overhaul of the system, going back to the original DC-9-30 design and reinventing it for modern transport with new engines, cockpit and other more modern systems. Historically, aircraft shrinks have sold poorly; examples of such aircraft in addition to the MD-87 include the Boeing 747SP, Boeing 737-600, Airbus A318, and Airbus A340-200.

Longtime McDonnell Douglas customer Scandinavian Airlines System (SAS) chose the Boeing 737-600 for its 100-seater over the MD-95 in March 1995. Then in October 1995, United States discount carrier ValuJet signed an order for 50 MD-95s, plus 50 options. McDonnell Douglas president Harry Stonecipher felt that launching MD-95 production on the basis of this small order was only a small risk, explaining that further orders would "take a while longer". The ValuJet order was the only order received for some two years.


As first proposed, the MD-95 was to be powered by a 16,500 lbf (73,000 N) thrust derivative of the JT8D-200 series, and the Rolls-Royce Tay 670 was also considered as an alternative. This was confirmed in January 1992, when Rolls-Royce and McDonnell Douglas signed a memorandum of understanding concerning the Tay-powered MD-95. McDonnell Douglas said that the MD-95 project would cost only a minimal amount to develop, as it was a direct offshoot of the IAE-powered MD-90.

During 1993 McDonnell Douglas seemed to be favoring a life extension program of the DC-9-30, under the program name DC-9X, to continue its presence in the 100-120 seat market, rather than concentrating on the new build MD-95. During its evaluation of the various engines available for the proposed re-engining component of DC-9X, McDonnell Douglas found the BMW Rolls-Royce BR700 engine an ideal candidate and the BMW Rolls-Royce BR700 engine was selected to power the aircraft on February 23, 1994.


McDonnell Douglas was planning for all MD-95 assembly to be undertaken in China, as an offshoot of the Trunkliner program, for which McDonnell Douglas had been negotiating to have up to 150 MD-90s built in China. The MD-90 Trunkliner deal was finalized in June 1992, but the contract was for a total of 40 aircraft, including 20 MD-80Ts and 20 -90Ts. The MD-80 has been license built in Shanghai since the 1980s. However in early 1993, MDC said that it was considering sites outside China, and was later seeking alternative locations for the assembly line. In 1994, McDonnell Douglas sought global partners to share development costs. It also began a search for a low-cost final assembly site. Halla Group in South Korea was selected to make the wings; Alenia of Italy the entire fuselage; Aerospace Industrial Development Corp. of Taiwan, the tail; ShinMaywa of Japan, the horizontal stabilizer; and a manufacturing division of Korea Air Lines, the nose and cockpit.

In an unprecedented move, McDonnell Douglas announced on November 8, 1994 that final assembly would be taken away from the longtime Douglas plant in Long Beach, California. Instead, it tapped a modifications and maintenance operation, Dalfort Aviation in Dallas, Texas, to assemble the MD-95. In early 1995, management and unions in Long Beach reached an agreement to hold down wage costs for the life of the MD-95 program and McDonnell Douglas canceled the preliminary agreement with Dalfort.

After McDonnell Douglas merged with Boeing in August 1997, most industry observers expected that Boeing would cancel development of the MD-95. However, Boeing decided to go forward with the design under a new name, Boeing 717. Some believed Boeing had skipped the 717 model designation when the 720, and then the 727 followed the 707. The 717 name had actually been used within the company to refer to the KC-135 Stratotanker. 717 had also been used to promote an early design of the 720 to airlines before it was modified to meet market demands. A Boeing historian notes that the Air Force plane had the designation "717-100" and the commercial airliner had the designation "717-200". The lack of a widespread use of the 717 name left it available to rebrand the MD-95.

At first Boeing had no more success selling the 717 than McDonnell Douglas. Even the original order for 50 was no certainty in the chaotic post-deregulation United States airline market. Assembly started on the first 717 in May 1997. The aircraft had its roll out ceremony on June 10, 1998. The 717's first flight took place on September 2, 1998. Following flight testing, the airliner was awarded a type certification on September 1, 1999. Its first delivery was to AirTran Airways in September 1999 and entered commercial service the following month.

Boeing's decision to go ahead with the 717 slowly began to pay off. Early 717 operators were delighted with the reliability and passenger appeal of the type and ordered more. The small Australian regional airline Impulse took a long-term lease on five 717s in early 2000 to begin an expansion into mainline routes. The ambitious move could not be sustained in competition with the majors, and Impulse sold out to Qantas in May 2001. This left Qantas with a more-or-less unwanted handful of 717s to spoil the efficiency of its fleet of large Boeing and small BAe 146 jets.

Within a few months, however, the abilities of the 717 became clear. It is roomier and faster than the BAe 146, cheaper to operate, and achieved a higher dispatch reliability, over 99%, than competing aircraft. Maintenance costs are very low: a C check inspection, for example, takes three days and is required once in 6,000 flying hours. (For comparison, its predecessor, the DC-9 needed 21 days for a C check.) The new Rolls-Royce BR715 engine design is highly modular: none of the line-replaceable units takes more than an hour to exchange.[citation needed] Many 717 operators, even accidental ones like Qantas, become converts to the plane. Qantas bought more 717s, and other significant orders came from Hawaiian Airlines and Midwest Airlines.

Boeing actively marketed the 717 to a number of large airlines, including Lufthansa and Northwest (who already operated a large fleet of DC-9 aircraft). Boeing also studied a stretched, higher-capacity version of the 717, to have been called 717-300, but decided against proceeding with the new model, fearing that it would encroach on the company's 737-700 model. Production of the original 717 continued. Boeing continued to believe that the 100-passenger market would be lucrative enough to support both the 717 and the 737-600, the smallest of the Next-Generation 737 series. While the aircraft were similar in overall size, the 737-600 was better suited to long-distance routes, while the lighter 717 was more efficient on shorter, regional routes.

The 100-seat market was overcrowded until 2001, but several potential competitors disappeared. BAe canceled its Avro RJX (an updated BAe 146 with modern engines); Fairchild Dornier closed its doors, taking the 728/928 project with it; and Bombardier canceled its new BRJ in favor of a less ambitious stretched 90-seat CRJ900. The remaining players are Boeing, Airbus with the A318, and Embraer with the E-195. The worldwide fleet was then largely made up of aging twinjets with relatively high operating costs, notably the DC-9, early model 737s, and the Fokker 100, plus the newer four-engined BAe 146, which is a prime prospect for refurbishment.

In 2001, Boeing began implementing a moving assembly line for production of the 717 and 737. The moving line greatly reduced production time, which led to lower production costs.

Following the slump in airline traffic caused by reaction to the September 11, 2001 attacks in the United States, Boeing announced a review of the type's future. After much deliberation, it was decided to continue with production. Despite the lack of orders, Boeing had confidence in the 717's fundamental suitability to the 100-seat market, and in the long-term size of that market. After 19 worldwide 717 sales in 2000, and just 6 in 2001, Boeing took 32 orders for the 717 in 2002, despite the severe industry downturn. Additionally, the former Douglas facility at Long Beach was producing only 717s and C-17s at this time.

End of production

Increased competition from regional jets manufactured by Bombardier and Embraer took a heavy toll on sales during the airline slump after 2001. The beginning of the end came in December 2003 when Boeing lost a US$2.7 billion contract from Air Canada, who chose the Embraer E-Jets and Bombardier CRJ over the 717. In January 2005, citing slow sales, Boeing announced that it planned to end production of the 717 after it had met all of its outstanding orders.

A major difficulty with the 717 model was its lack of commonality with other Boeing aircraft. The 717 had no commonality with other aircraft, even prior MD-80 and DC-9 aircraft upon which it was based. The trend with aircraft manufacturers, particularly Airbus, was to make a "family" of aircraft with similar cockpits and systems, which would require only one "type-rating" for a crew. That way, whatever size of aircraft that was required on a particular route—even changing down to the day if necessary—could be used with any of the crew type-rated for the family. Although the 717 had operating costs 10% lower than the A318, airlines considering the 717 could not take advantage of the cost savings gained through commonality. Airbus used a commonality approach starting with their A320 narrow-body family (including A318, A319, and A321), and Boeing embraced this concept with their Next-Generation 737-600, -700, -800, and -900 models. Embraer, in their new E-Jet family, also took this approach, offering four regional aircraft in a common family, the largest of which had operational capabilities very close to the 717.

The 156th and final 717 rolled off the assembly line in April 2006 for AirTran Airways, which was the 717's launch customer as well as its final customer. The final two Boeing 717s were delivered to customers AirTran and Midwest Airlines on May 23, 2006. The 717 was the last commercial airplane produced at Boeing's Long Beach facility in Southern California.

The 717 features a two-crew cockpit that incorporates six interchangeable liquid-crystal-display units and advanced Honeywell VIA 2000 computers. The cockpit design is called Advanced Common Flightdeck (ACF) and is shared with the MD-11. Flight deck features include an Electronic Instrument System, a dual Flight Management System, a Central Fault Display System, and Global Positioning System. Category IIIb automatic landing capability for bad-weather operations and Future Air Navigation Systems are available. The 717 shares the same type rating as the DC-9 such that FAA approved transition courses for DC-9 and analog MD-80 pilots can be completed in 11 days.

In conjunction with Parker Hannifin, MPC Products of Skokie, Illinois designed a fly-by-wire technology mechanical control suite for the 717 flight deck. The modules replaced much cumbersome rigging that had occurred in previous DC-9/MD-80 aircraft. The Rolls-Royce BR715 engines are completely controlled by an electronic engine system (FADEC — Full Authority Digital Engine Control) developed by BAE Systems, offering improved controllability and optimization over its predecessors.

Like its DC-9/MD-80/MD-90 predecessors, the 717 has a 2+3 seating arrangement in coach, providing only one middle seat per row, whereas other single-aisle twin jets often have 3+3 arrangement with two middle seats per row. Unlike its predecessors, McDonnell Douglas decided not to offer the 717 with the boarding flexibility of aft airstairs, with the goal of maximizing fuel efficiency through the reduction and simplification of as much auxiliary equipment as possible.


Three initial variants were proposed by McDonnell Douglas in 1993:

  • MD-95-30: Baseline aircraft with 100 seats.
  • MD-95-30ER: extended range (with additional fuel), and
  • MD-95-50: a slightly larger with standard capacity for 122 passengers.

Boeing 717 Business Express

Boeing 717 Business Express was a proposed corporate version of 717-200, unveiled at EBACE Convention in Geneva, Switzerland in May 2003. Configurable for 40 to 80 passengers in first and/or business class interior (typically, 60 passengers with seat pitch of 52 in, 132 cm). Maximum range in HGW configuration with auxiliary fuel and 60 passengers was 3,140 nmi (5,815 km; 3,613 mi). The version complements BBJ family.

Undeveloped variants

Boeing 717-100 (-100X): Proposed 86-seat version, formerly MD-95-20; four frames (6 ft 3 in, 1.9 m) shorter. Renamed -100X; wind tunnel tests began in early 2000; revised mid-2000 to eight-frame (12 ft 8 in, 3.86 m) shrink. Launch decision was deferred in December 2000 and again thereafter to an undisclosed date. Shelved by mid-2003.

Boeing 717-100X Lite: Proposed 75-seat version, powered by Rolls-Royce Deutschland BR 710 turbofans; later abandoned.

Boeing 717-300X: Proposed stretched version, formerly MD-95-50; studies suggest typical two-class seating for 130 passengers, with overall length increased to 138 ft 4 in (42.16 m) by addition of nine frames (five forward and four aft of wing); higher MTOW and space-limited payloads weights; additional service door aft of wing; and 21,000 lb (93.4 kN) BR 715C1-30 engines. AirTran expressed interest in converting some -200 options to this model. Was under consideration late 2003 by Star Alliance Group (Air Canada, Austrian Airlines, Lufthansa and SAS); interest was reported from Delta, Iberia and Northwest Airlines.
