McDonnell Douglas MD-82 (DC-9-82)
 

The McDonnell Douglas MD-80 series are twin-engine, medium-range, single-aisle commercial jet airliners. The MD-80 aircraft were lengthened and updated from the DC-9. The MD-80 series can seat from 130 up to 172 passengers depending on variant and seating arrangement.

The MD-80 series was introduced into commercial service on October 10, 1980 by Swissair. The MD-80 series was followed into service in modified form by the MD-90 in 1995 and the MD-95/Boeing 717 in 1999.

Design and development

Background
Douglas Aircraft developed the DC-9 in the 1960s as a short-range companion to their larger DC-8. The DC-9 was an all-new design, using two rear fuselage-mounted turbofan engines, and a T-tail. The DC-9 has a narrow-body fuselage design with 5-abreast seating, and holds 80 to 135 passengers depending on seating arrangement and aircraft version.

The MD-80 series was the second generation of the DC-9. It was originally called the DC-9-80 series and the DC-9 Super 80 and entered service in 1980. The MD-80 series was then developed into the MD-90 entering service in 1995. The last variant of the family was the MD-95, which was renamed theBoeing 717-200 after McDonnell Douglas's merger with Boeing in 1997.

The DC-9 family is one of the most successful jet airliners with a total of over 2,400 units produced; it ranks third behind the second place Airbus A320 family with over 4,000 produced, and the first place Boeing 737 with over 6,000 produced.

MD-80 series
The MD-80 series is a mid-size, medium-range airliner that was introduced in 1980. The design was the second generation of the DC-9 with two rear fuselage-mounted turbofan engines, small, highly efficient wings, and a T-tail. The aircraft has distinctive 5-abreast seating in coach class. It was a lengthened DC-9-50 with a higher maximum take-off weight (MTOW) and a higher fuel capacity. The aircraft series was designed for frequent, short-haul flights for 130 to 172 passengers depending on plane version and seating arrangement.

The development of MD-80 series began in the 1970s as a growth version of the DC-9 Series 50. Availability of new Pratt & Whitney JT8D higher bypass engines drove early studies including designs known as Series 55, Series 50 (Re-fanned Super Stretch), and Series 60. The design effort focused on the Series 55 in August 1977. With the projected entry into service in 1980, the design was marketed as the "DC-9 Series 80". Swissair launched the Series 80 in October 1977 with an order for 15 plus an option for five.

The Series 80 featured a fuselage 14 feet 3 in (4.34 m) longer than the DC-9-50. The DC-9 wings were redesigned by adding sections at the wing root and tip for a 28% larger wing. The initial Series 80 first flew October 19, 1979.

It entered service in 1980. Originally it was certified as a version of the DC-9, but was changed to MD-80 in July 1983, as a marketing move. New versions of the series were initially the MD-81/82/83 and the shortened MD-87, even though their formal certification was DC-9-81/82 etc. Only the MD-88 was given an "MD" certification, as was the later MD-90.

The MD-80 versions have cockpit, avionics and aerodynamic upgrades along with the more powerful, more efficient and quieter JT8D-200 series engines, which are a significant upgrade over the smaller JT8D-15, -17, -11, and -9 series. The MD-80 series aircraft also have longer fuselages than their earlier DC-9 counterparts, as well as longer range. The MD-80's production ended in 1999. Some customers, such as American Airlines, still refer to the planes in fleet documentation as "Super 80". This model is still flown extensively by American Airlines and Delta Air Lines. Comparable airliners to the MD-80 series include the Boeing 737 and Airbus A320.

Flight testing and certification
The first MD-80, DC-9 line number 909, made its first flight on October 19, 1979. Test flying, despite two aircraft being substantially damaged in accidents, was completed on August 25, 1980, when the first variant of MD-80, the JT8D-209-powered MD-81 (or DC-9-81), was certificated under an amendment to the FAA Type Certificate for the DC-9. The flight testing leading up to certification had involved three aircraft accumulating a total of 1085 flying hours on 795 flights. The first delivery, to launch customer Swissair took place on September 13, 1980.

Model designation
As the MD-80 was not in effect a new aircraft, it continues to be operated under an amendment to the original DC-9 FAA aircraft Type Certificate (a similar case to the later MD-90 and Boeing 717 aircraft). The Type Certificate issued to the aircraft manufacturer carries the aircraft model designations exactly as it appears on the manufacturer's application, including use of hyphens or decimal points, and should match what is stamped on the aircraft's data or nameplate. What the manufacturer chooses to call an aircraft for marketing or promotional purposes is irrelevant to the airworthiness authorities. The first amendment to the DC-9 type certificate for the new MD-80 aircraft was applied as DC-9-81 which approved on August 26, 1980. All MD-80 models have since been approved under additional amendments to the DC-9 Type Certificate. In 1983, McDonnell Douglas decided that the DC-9-80 (Super 80) would be designated the MD-80. However, instead of merely using the MD- prefix as a marketing symbol, an application was made to again amend the Type Certificate to include the MD-81, MD-82, and MD-83. This change was dated March 10, 1986, and the Type Certificate declared that although the MD designator could be used in parentheses, it must be accompanied by the official designation, for example: DC-9-81 (MD-81). All Long Beach aircraft in the MD-80 series thereafter had MD-81, MD-82, or MD-83 stamped on the aircraft nameplate. Although not certified until October 21, 1987, McDonnell Douglas had already applied for models DC-9-87 and DC-9-87F on February 14, 1985. Third derivative was similarly officially designated DC-9-87 (MD-87), although no nameplates were stamped DC-9-87. For the MD-88, an application for a Type Certificate model amendment was made after the earlier changes, so there never was a DC-9-88, only the MD-88, which was certificated on December 8, 1987.

MD-80 production
The MD-80 was produced on a common line with the DC-9 with which it shares its line number sequence. However after the delivery of 976 DC-9s and 108 MD-80s, McDonnell Douglas stopped DC-9 production. Hence, commencing with the 1,085th DC-9/MD-80 delivery, an MD-82 for VIASA in December 1982, all DC-9s produced have been Series 80s/MD-80s.

As well as the Long Beach line, a second assembly line was set up at Shanghai, where aircraft were to be built under license.

During 1991, MD-80 production had reached a peak of 12 per month, having been running at approximately 10 per month since 1987 and was expected to continue at this rate in the near term (140 MD-80s were delivered in 1991). As a result of the decline in the air traffic and a slow market response to the MD-90, MD-80 production has been reduced, and 84 aircraft were handed over in 1992. A further production rate cut saw 42 MD-80s delivered during 1993 (3.5 per month) and 22 aircraft were handed over.

Derivative designs
The MD-90 was developed from the MD-80 series and is a 5-foot-longer (1.5 m), updated version of the MD-88 with a similar electronic flight instrument system (EFIS) (glass cockpit), and improved, and quieter IAE V2500 turbofan engines. The MD-90 program was begun in 1989, first flown in 1993, and entered commercial service in 1995.

A number of other variants were proposed that never entered production. One proposal was the MD-94X which was fitted with unducted fan turbofan engines. Previously, an MD-81 was used as a testbed for unducted fan engines, such as the General Electric GE36 and the Pratt & Whitney/Allison 578-DX.

The MD-95 was developed to replace early DC-9 models, then approaching 30 years old. The project completely overhauled the original DC-9 into a modern airliner. It is slightly longer than the DC-9-30 and is powered by new Rolls-Royce BR715 engines. The MD-95 was renamed Boeing 717 after the McDonnell Douglas—Boeing merger in 1997.

Operational history

The MD-80 series has been used by airlines around the world. Major customers have included Aeroméxico, Alaska Airlines, Alitalia, Allegiant Air, American Airlines, Austral Líneas Aéreas, Austrian Airlines, Avianca, China Eastern Airlines, China Northern Airlines, Delta Air Lines, Finnair, Iberia, Japan Air System (JAS), Korean Air, Lion Air, Reno Air, Scandinavian Airlines System (SAS), Spanair, Insel Air, and Swissair.

Due to the usage of the aging JT8D engine, the MD-80 is not fuel efficient compared to the A320 or newer 737 models; it burns 1,050 gallons of jet fuel per hour on a typical flight, while the larger Boeing 737-800 burns only 850 gallons per hour (19% reduction). Many airlines have started to retire the type in the 2000s. Alaska Airlines' tipping point in using the 737-800 was the $4 per gallon price of jet fuel the airline was paying by the summer of 2008; the airline stated that a typical Los Angeles-Seattle flight would cost $2,000 less, using a Boeing 737-800, than the same flight using an MD-80. American Airlines has announced plans to retire at least 20 MD-80s, and has accelerated delivery of new 737-800s, while Midwest Airlines announced on July 14, 2008, that it would retire all 12 of its MD-80s (used primarily on routes to the west coast) by the fall. The JT8D's comparatively lower maintenance costs due to simpler design help narrow the fuel cost gap.

Variants

➽ McDonnell Douglas MD-81 (DC-9-81)

The MD-81 (or as it was originally known the DC-9 Super 81) was the first production model of the MD-80, and apart from the MD-87, the differences between the various long body MD-80 variants is relatively minor. The four long body models (MD-81, MD-82, MD-83, and MD-88) only differ from each other in having different engine variants, fuel capacities, and weights. The MD-88 and later build versions of the other models have more up-to-date flight decks featuring for example EFIS.

Dimensions: The basic "long body" MD-80 versions (MD-81, MD-82, MD-83, and MD-88) have an overall length of 147 feet 10 inches (45.06 m), and a fuselage length of 136 feet 5 inches (41.58 m) that is 4.62 m longer than the DC-9-50 and 13.51 m longer than the initial DC-9, the Series 10. Wingspan was also increased by 4.4 m in comparison with earlier DC-9s at 107 feet 10.2 inches (32.873 m). The aircraft's passenger cabin, from cockpit door to aft bulkhead, is 101 feet 0 inches (30.78 m) long and, as with all versions of the DC-9, has a maximum cabin width (trim-to-trim) of 123.7 inches (3.14 m).

Powerplant: The initial production version of the MD-80 was the Pratt and Whitney JT8D-209 18,500 lbf (82 kN) thrust powered MD-81. Later build MD-81s have been delivered with more powerful JT8D-217 and -219 engines.

APU: All versions of the MD-80 are equipped with an AlliedSignal (Garrett) GTCP85-98D APU as standard which is located in the aft fuselage.

Performance: Standard MTOW on the MD-81 is 140,000 lb with the option to increase to 142,000 lb. Fuel capacity is 5,840 US gallons (22,100 L), and typical range, with 155 passengers, is 1,565 nmi.

Flight Deck: The MD-80 is equipped with a two crew flightdeck similar to that on the DC-9 from which it evolved. Later models could be equipped to a higher specification with EFIS displays in place of the traditional analogue instruments, TCAS, windshear detection, etc. An EFIS retrofit to non-EFIS equipped aircraft is possible.

Cabin: Typical passenger cabin seating arrangements include:

  • A mixed class, with aft full service galley, configuration for a total of 135 passengers with 12 first class, four-abreast 36 in seat pitch.
  • 123 economy class passengers, five-abreast, 32 in pitch.
  • All economy layout for 155 passengers, five-abreast, 32 in and 33 in pitch.
  • A typical high density layout is for 167 one class (ie Airtours).

Undercarriage: All versions of the MD-80 are equipped with a tricycle undercarriage, featuring a twin nose unit with spray deflector and twin main units with rock deflectors. The MD-80T, developed for the Chinese, differs in that the main units are each fitted with a four wheel double main bogey undercarriage to reduce pavement loading.

Aerodynamic Improvements: From mid-1987 new MD-87-style low drag "beaver" tail cones were introduced on all Series of MD-80s reducing drag and hence improving fuel burn. However it would seem that some operators have been modifying the old DC-9-style cones on earlier build MD-80s to the new low drag style. SAS is one airline that has done this, citing both the improved economics as well as cosmetic improvement for the modification.

➽ McDonnell Douglas MD-82 (DC-9-82)

Announced on April 16, 1979, the MD-82 was a new MD-80 variant dimensionally similar to the MD-81 but equipped with more powerful engines. The MD-82 was intended for operation from 'hot and high' airports but also offered greater payload/range when in use at 'standard' airfields. American Airlines is the worlds largest operator of the MD-82, with at one point over 300 MD-82s in the fleet, but the number now stands around 200.

Powerplant: Originally certificated with 20,000 lbf (89 kN) thrust JT8D-217s, a -217A powered MD-82 was certificated in mid-1982 and became available in Autumn 1982. The new version featured a higher MTOW (149,500 lb), while the JT8D-217As had a guaranteed take-off thrust at temperature of up to 29 degrees C or 5,000 ft altitude. The JT8D-217C engines were also offered on the MD-82 giving improved sfc. Several operators have taken delivery of the -219-powered MD-82s, while Balair ordered its MD-82s powered by the lower thrust -209 engine.

Performance: The MD-82 features an increased standard MTOW initially to 147,000 lb, and this was later increased to 149,500 lb. Standard fuel capacity is the same as the MD-81, 5,840 US gal, and typical range with 155 passengers is 2,050 nautical miles (3,800 km).

MD-82 timeline

  • Announced/go-ahead: April 16, 1979.
  • First flight: January 8, 1981.
  • FAA certification: July 29, 1981.
  • First delivery: August 5, 1981 to Republic Airlines.
  • Entry into service: August, 1981 with Republic Airlines.
  • Last delivery: November 17, 1997 to U-Land Airlines of Taiwan.

The MD-82 was assembled under licence in Shanghai by the Shanghai Aviation Industrial Corporation (SAIC) since November 1986; the sub-assemblies were delivered by McDonnell Douglas in kit form.

➽ McDonnell Douglas MD-83 (DC-9-83)

The MD-83 is a longer range development of the basic MD-81/82 with higher weights, more powerful engines, increased fuel and hence longer range.

Powerplant: Compared to earlier models, the MD-83 is equipped with slightly more powerful 21,000 lbf (93 kN) thrust Pratt and Whitney JT8D-219s as standard.

Performance: The MD-83 features increased fuel capacity as standard (to 6,970 US gal) which is carried in two 565 US gallons auxiliary tanks located fore and aft of the centre section. The aircraft also has higher operating weights, with MTOW increased to 160,000 lb and MLW to 139,500 lb. Typical range for the MD-83 with 155 passengers is around 2,504 nautical miles (4,637 km). To cope with the higher operating weights, the MD-83 incorporates strengthened landing gear including new wheels, tyres and brakes, changes to the wing skins, front spar web and elevator spar cap and strengthened floor beams and panels to carry the auxiliary fuel tanks. However, from MD-80 line number 1194, an MD-81 delivered in September 1985, it is understood that all MD-80s have the same basic wing structure and in theory could be converted to MD-83 standard.

MD-83 timeline

  • Announced/go-ahead: January 31, 1983.
  • First flight: December 17, 1984.
  • FAA certification: October 17, 1985 (MTOW 149,500 lb). MTOW of 160,000 lb certificated November 4, 1985.
  • First delivery: February, 1985 to Alaska Airlines - initially as -82 powered by -217A engines and certificated as MD-82s. Alaska Airlines' first four aircraft were subsequently re-engined and re-certificated as MD-83s.
  • Entry into service: February, 1985 with Alaska Airlines.
  • Last delivery: December 28, 1999 to TWA.

➽ McDonnell Douglas MD-87 (DC-9-87)

In January 1985 McDonnell Douglas announced that it was to produce a shorter fuselage MD-80 development aircraft, designated the MD-87, which would seat between 109 and 130 passengers depending upon configuration. The designation was intended to indicate its planned date of entry into service, 1987.

Dimensions: With an overall length of 130 feet 5 inches (39.75 m), the MD-87 is 17 feet 4 inches (5.28 m) shorter than the other MD-80s but is otherwise generally similar to them, employing the same engines, systems and flight deck. The MD-87 features modifications to its tail, with a fin extension above the tailplane. It also introduced a new low drag "beaver" tail cone which became standard on all MD-80s.

Powerplant: The MD-87 was offered with either the 20,000 lbf (89 kN) thrust JT8D-217C or the 21,000 lbf (93 kN) thrust -219.

Performance: Two basic versions of the MD-87 were made available with either an MTOW of 140,000 lb and MLW of 128,000 lb or an MTOW of 149,000 and an MLW of 130,000 lb. Fuel capacity is 5,840 US gallons (22,100 l), increasing to 6,970 US gallons (26,400 l) with the incorporation of two auxiliary fuel tanks. Typical range with 130 passengers, is 2,370 nautical miles (4,390 km) increasing to 2,900 nautical miles (5,400 km) with two auxiliary fuel tanks.

Cabin: The MD-87 provides typical mixed class seating for 114 passengers or 130 in an all economy layout (five-abreast 31 in and 32 in seat pitch). The maximum seating, exit limited, is for 139 passengers.

MD-87 timeline

  • Announced/go-ahead: January 1985.
  • First flight: December 4, 1986.
  • FAA certification: October 21, 1987.
  • First delivery: November 27, 1987 to Austrian Airlines.
  • Last delivery: March 27, 1992 to Scandinavian Airlines (SAS).

➽ McDonnell Douglas MD-88

The MD-88 was the last variant of the MD-80 which was launched on January 23, 1986 on the back of orders and options from Delta Air Lines for a total of 80 aircraft.

The MD-88 is, depending on specification, basically similar to the MD-82 or MD-83 except that it incorporates an EFIS cockpit instead of the more traditional analogue flight deck of the other MD-80s. Other changes incorporated in the MD-88 include a windshear warning system and general updating of the cabin interior/trim, however these detail changes are relatively minor and were written back as standard on the MD-82/83. In fact the windshear warning, was offered as a standard option on all the other MD-80s and has been made available for retrofitting on earlier aircraft including the DC-9.

Delta's earlier delivered MD-82s were upgraded to MD-88 specification. When McDonnell Douglas was asked why these aircraft were MD-88s and not MD-82s they said that the customer, Delta Air Lines, thought that its specification was sufficiently different to warrant a new designation. Although delivered in December 1987, Delta only put the aircraft into service in January 1988.

Performance: The MD-88 has the same weights, range and airfield performance as the other long body aircraft (MD-82 and MD-83) and is powered by the same engines. MDC quotes a typical range for the MD-88 as 2,050 nautical miles (3,800 km) with 155 passengers. Range with 155 passenger is increased to 2,504 nautical miles (4,637 km) with two additional auxiliary fuel tanks (similar to the MD-83).

MD-88 timeline

  • Announced/go-ahead: January 23, 1986.
  • First flight: August 15, 1987.
  • FAA certification: December 8, 1987.
  • First delivery: December 19, 1987 to Delta Air Lines.
  • Entry into service: January 5, 1988 with Delta Air Lines.
  • Last delivery: June 25, 1997 to Onur Air.

Undeveloped variants

MD-80 Advanced

McDonnell Douglas revealed at the end of 1990 that it was developing an MD-80 improvement package which it intended to begin offering in early 1991 for delivery from mid-1993. The aircraft became known as the MD-80 Advanced. The main improvement involved the installation of Pratt and Whitney JT8D-290 engines which featured a fan 1.5 in greater in diameter and would, it was hoped, allow a 6 dB reduction in exterior noise.

Due to lack of market interest however, McDonnell Douglas dropped its plans to offer the MD-80 Advanced during 1991. However a "mark 2" MD-80 Advanced reappeared during 1993, which did not now feature the modified JT8D-290 engines as previously proposed. The company also evaluated the fitment of winglets on the MD-80. In late 1993 Pratt and Whitney launched a modified version of the JT8D-200 series, the -218B, which was being offered for the DC-9X re-engining programme, and is also evaluating the possibility of developing a new JT8D for possible retrofit on the MD-80. The engine would also be offered on new build MD-80s.

The 18,000 lbf (80 kN) to 19,000 lbf (85 kN) thrust -218B engines shares 98% commonality with the existing engine, with changes designed to reduce NOx, improve durability, and bring noise levels to 3 dB. The 218B could be certificated in early to mid-1996. The new engine, dubbed the "8000", was to feature a new fan of increased diameter (by 1.7 in), extended exhaust cone, a larger LP compressor, a new annular burner and a new LP turbine and mixer. The initial thrust rating would be around 21,700 lbf (97 kN) thrust. A launch decision on the new engine was expected in the first half of 1994, but never occurred.

In addition to the engine, which existed only on paper, the MD-80 Advanced was to offer a new flight deck instrumentation package and a completely new passenger compartment design. All would available in retrofit for existing MD-80s and was forecast to be in service by July 1993.

The MD-80 Advanced was to incorporate the advanced flight deck of the MD-88, including a choice of reference systems, with an inertial reference system as standard fitting and optional attitude-heading equipment. It was to be equipped with an electronic flight instrument system (EFIS), an optional second flight management system (FMS), light emitting diode (LED) dot matrix electronic engine and system displays. A Honeywell windshear computer and provision for an optional traffic-alert and collision avoidance system (TCAS) were also to be included. A new interior would have a 12% increase in overhead baggage space and stowage compartment lights that come on when the door opens, as well as new video system featuring drop-down LCD monitors above.

The lack of market interest received for the MD-80 Advanced during 1991 led to McDonnell Douglas dropping its plans for the development.

Derivatives

The MD-90-30 is a stretched variant with updated glass cockpit and two V2500 engines, also Extended Range (ER) version as the MD-90-30ER.

The MD-95 was developed as a replacement for the earlier DC-9-30, produced as the Boeing 717.

Operators

In July 2009, there were 886 MD-80 series aircraft in service, and that number had dropped to 844 in July 2010. Commercial operators in July 2010 included American Airlines (282), Delta Air Lines (117), Allegiant Air (66), Alitalia (39), SAS (36), Austral Líneas Aéreas (23), Meridiana (17), Khors Air (14), 1Time Airline (12), Bulgarian Air Charter (12), Wings Air (11), and others with fewer aircraft.

Incidents and accidents

As of November 2009, the MD-80 series has been involved in 60 incidents, including 27 hull-loss accidents, with 1,177 fatalities.

Notable accidents and incidents

  • On December 1, 1981, an Inex-Adria Aviopromet Flight 1308, an MD-81 crashed into Corsica's Mt. San Pietro during a holding pattern for landing at Campo dell'Oro Airport, Ajaccio. All 180 passengers and crew were killed.
  • On August 16, 1987, Northwest Airlines Flight 255, an MD-82 crashed shortly after takeoff from Detroit Metropolitan Wayne County Airport due to flight crew's failure to use the taxi checklist to ensure the flaps and slats were extended for takeoff according to the NTSB. All crew and passengers were killed with the exception of a 4-year old girl, Cecelia Cichan.
  • On December 27, 1991, SAS Flight 751, an MD-81, OY-KHO "Dana Viking" crash landed at Gottröra, Sweden. In the initial climb both engines ingested ice broken loose from the wings (which had not been properly de-iced before departure). The ice damaged the compressor blades causing compressor stall. The stall further caused repeated engine surges that finally destroyed both engines, leaving the aircraft with no propulsion. The aircraft landed in a snowy field and broke in three parts. No fire occurred and all aboard survived.
  • On June 1, 1999, American Airlines Flight 1420, an MD-82 attempting to land in severe weather conditions at Little Rock Airport overshot the runway and crashed into the banks of the Arkansas River. Eleven people, including the captain, died.
  • On January 31, 2000, Alaska Airlines Flight 261, an MD-83, crashed in the Pacific Ocean, due to loss of horizontal stabilizer control. All 88 people on board were killed. Following the crash, the acme nut and jackscrew recovered from the aircraft were found to be excessively worn and found to be the cause of the crash due to inadequate maintenance. The FAA ordered airlines to inspect and lubricate the jackscrew more frequently.
  • On October 8, 2001, Scandinavian Airlines Flight 686, an MD-87 (SE-DMA) collided with a small Cessna jet during take-off at Linate Airport, Milan, Italy. The Linate Airport disaster left 118 people dead. The cause of the accident was a misunderstanding between air traffic controllers and the Cessna jet, and the SAS crew had no role in causing the accident. Also the ground movement radar was inoperative at the time of the accident.
  • On May 7, 2002, China Northern Airlines Flight 6136, an MD-82, from Beijing to Dalian, crashed into Bohai Bay near Dalian, after the pilot reported "fire on board". All 111 people on board were killed.
  • On November 30, 2004, Lion Air Flight 538, an MD-82 crash landed at Adi Sumarmo Airport in Surakarta and overran the end of the runway. There were 25 fatalities.
  • On August 16, 2005, West Caribbean Airways Flight 708, an MD-82 crashed in a mountainous region in northwest Venezuela killing all 152 passengers and eight crew.
  • On March 4, 2006, Lion Air Flight 8987, an MD-82, after landing at Juanda International Airport reverse thrust was used although stated to be out of order, this caused the aircraft to veer to the right and skid off the runway coming to rest 7,000 ft from the approach end of RWY10.
