McDonnell Douglas MD-80 to MD-88

The McDonnell Douglas MD-80 is a series of twin-engine, short- to medium-range, single-aisle commercial jet airliners. It was lengthened and updated from the DC-9. This series can seat from 130 to 172 passengers depending on variant and seating configuration.

The MD-80 series was introduced into commercial service on October 10, 1980 by Swissair. The series includes the MD-81, MD-82, MD-83, MD-87, and MD-88. These all have the same fuselage length except the shortened MD-87. The 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

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 five-abreast seating, and holds 80 to 135 passengers depending on seating arrangement and aircraft version. 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 6,600 produced, and the first place Boeing 737 with over 8,600 produced.

MD-80 series

The development of MD-80 series began in the 1970s as a lengthened, growth version of the DC-9-50, with a higher maximum take-off weight (MTOW) and a higher fuel capacity. Availability of newer versions of the Pratt & Whitney JT8D engine with higher bypass ratios drove early studies including designs known as Series 55, Series 50 (refanned 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 series is a mid-size, medium-range airliner. The series featured a fuselage 14 ft 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 was certified as a version of the DC-9.

The aircraft has distinctive five-abreast seating in the coach class. The aircraft series was designed for frequent, short-haul flights for 130 to 172 passengers depending on plane version and seating arrangement.

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. 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 737-400 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 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 certified 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 1,085 flying hours on 795 flights. The first delivery, to launch customer Swissair took place on September 13, 1980.

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. 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. The 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 was not a DC-9-88, which was certified on December 8, 1987. The FAA's online aircraft registry database shows the DC-9-88 and DC-9-80 designations in existence but unused.

Production

The second generation (later named MD-80s) was produced on a common line with the first generation DC-9s, with which it shares its line number sequence. 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 were Series 80s/MD-80s.

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 was reduced, and 84 aircraft were handed over in 1992. A further production rate cut resulted in 42 MD-80s delivered during 1993 (3.5 per month) and 22 aircraft were handed over. MD-80 production ended in 1999.

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 began in 1989, first flown in 1993, and entered commercial service in 1995.

Several other proposed variants 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.

Freighter conversions

In February 2010, Aeronautical Engineers Inc. based in Miami, Florida announced it was beginning a freighter conversion program for the MD-80 series. The converted aircraft use the "MD-80SF" designation. AEI was the first firm to receive a supplemental type certificate for the MD-80 family from the FAA in February 2013. The first conversion was undertaken on an ex-American Airlines MD-82 aircraft, which used as a testbed for the supplemental type. The MD-80SF made its inaugural flight on 28 September 2012. Currently, AEI is certified to perform conversions on MD-81, MD-82, MD-83, and MD-88 aircraft. The launch customer for the conversion service is Everts Air Cargo. In October 2015, the MD-80SF was approved by the EASA. The first MD-80SF was delivered to Everts Air Cargo in February 2013.

Operational history

The MD-80 series has been used by airlines around the world. Major customers have included Aerolíneas Argentinas, Aeroméxico, Aeropostal Aerorepublica, Alaska Airlines, Alitalia, Allegiant Air, American Airlines, Aserca, 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, Martinair Holland, Pacific Southwest Airlines (PSA), Reno Air, Scandinavian Airlines System (SAS), Spanair, Insel Air, Swissair, and Trans World Airlines.

Due to the use of the aging JT8D engines, the MD-80 is not fuel efficient compared to the A320 or newer 737 models; it burns 1,050 US gal (4,000 l) of jet fuel per hour on a typical flight, while the larger Boeing 737-800 burns 850 US gal (3,200 l) per hour (19% reduction). Starting in the 2000s, many airlines began to retire the type. 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

MD-81

The MD-81 (or as it was originally known the DC-9 Super 81 or DC-9-81) 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 ft 10 in (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 13.5 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 (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 maximum take-off weight (MTOW) on the MD-81 is 140,000 lb (64,000 kg) with the option to increase to 142,000 lb (64,000 kg). 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-inch seat pitch.
  • 123 economy-class passengers, five-abreast, 32 in pitch.
  • All-economy layout for 155 passengers, five-abreast, 32- and 33-inch pitch.
  • A typical high-density layout is for 167 one class (i.e., 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 improving fuel burn. Some operators have been modifying the old DC-9-style cones on earlier-build MD-80s to the new low-drag style. Scandinavian Airlines System has done this, citing the improved economics and cosmetics from the modification.

MD-81 timeline :

  • First flight: October 18, 1979.
  • FAA certification: August 25, 1980.
  • First delivery: September 13, 1980 to Swissair.
  • Entry into service: October 10, 1980 with Swissair on a flight from Zurich to Heathrow.
  • Last delivery: June 24, 1994 to JAL Domestic.

MD-82

Announced on April 16, 1979, the MD-82 (DC-9-82) was a new MD-80 variant with similar dimensions to those of 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 world's largest operator of the MD-82, with at one point over 300 MD-82s in the fleet.

Originally certified with 20,000 lbf (89 kN) thrust JT8D-217s, a -217A-powered MD-82 was certified in mid-1982 and became available that year. The new version featured a higher MTOW (149,500 lb (67,800 kg)), while the JT8D-217As had a guaranteed take-off thrust at temperature of up to 29 degrees C or 5,000 ft (1,500 m) altitude. The JT8D-217C engines were also offered on the MD-82, giving improved Thrust specific fuel consumption (TSFC). Several operators took delivery of the -219-powered MD-82s, while Balair ordered its MD-82s powered by the lower-thrust -209 engine.

The MD-82 features an increased standard MTOW initially to 147,000 lb (67,000 kg), and this was later increased to 149,500 lb (67,800 kg). Standard fuel capacity is the same as that of the MD-81, 5,840 US gal (22,100 L), and typical range with 155 passengers is 2,050 nmi (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 license in Shanghai by the Shanghai Aviation Industrial Corporation (SAIC) beginning in November 1986; the sub-assemblies were delivered by McDonnell Douglas in kit form. China had begun design on a cargo version, designated Y-13, but the project was subsequently cancelled with the conclusion of the licensed assembly of the MD-82 and MD-90 in China. In 2012, Aeronautical Engineers Inc. performed the first commercial freighter conversion of an MD-82.

MD-83

The MD-83 (DC-9-83) is a longer range version of the basic MD-81/82 with higher weights, more powerful engines, and increased fuel capacity.

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 (26,400 L)), which is carried in two 565 US gal (2,140 L) auxiliary tanks located fore and aft of the center section. The aircraft also has higher operating weights, with MTOW increased to 160,000 lb (73,000 kg) and MLW to 139,500 lb (63,300 kg). 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, tires, 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. 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 (67,800 kg)). MTOW of 160,000 lb (73,000 kg) certified November 4, 1985.
  • First delivery: February, 1985 to Alaska Airlines – initially as -82 powered by -217A engines and certified as MD-82s. Alaska Airlines' first four aircraft were subsequently re-engined and re-certified as MD-83s.
  • Entry into service: February, 1985 with Alaska Airlines.
  • Last delivery: December 28, 1999 to TWA.

MD-87

In January 1985 McDonnell Douglas announced it would produce a shorter fuselage MD-80 variant, designated MD-87 (DC-9-87), 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 ft 5 in (39.75 m), the MD-87 is 17 ft 4 in (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 (64,000 kg) and MLW of 128,000 lb (58,000 kg) or an MTOW of 149,000 lb (68,000 kg) and an MLW of 130,000 lb (59,000 kg). Fuel capacity is 5,840 US gal (22,100 l), increasing to 6,970 US gal (26,400 l) with the incorporation of two auxiliary fuel tanks. Typical range with 130 passengers, is 2,370 nmi (4,390 km) increasing to 2,900 nmi (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).

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 it incorporates an EFIS cockpit instead of the more traditional analog flight deck of the other MD-80s. Other changes incorporated into the MD-88 include a wind-shear warning system and general updating of the cabin interior/trim. These detail changes are relatively minor and were written back as standard on the MD-82/83. The wind-shear warning system was offered as a standard option on all 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 specifications. When McDonnell Douglas was asked why these aircraft were MD-88s and not MD-82s, they said the customer, Delta Air Lines, thought its specification was sufficiently different to warrant a new designation. MD-88 deliveries began in December 1987 and it entered service with Delta 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 nmi (3,800 km) with 155 passengers. Range with 155 passengers is increased to 2,504 nmi (4,637 km) with two additional auxiliary fuel tanks (similar to the MD-83). According to a Wall Street Journal article published March 9, 2015, "pilots and other safety experts have long known that when the MD-88's reversers are deployed, its rudder..sometimes may not be powerful enough to control deviations to the left or right from the center of a runway..safety board investigators, among other things, are looking to see if this tendency played any role in the crash." referring to the crash of an MD-88 at New York City's La Guardia Airport. See the entry in Notable accidents and Incidents below.

Operators

There were 426 MD-80 series aircraft in service as of July 2015, with operators including Delta Air Lines (116), American Airlines (114) and Allegiant Air (52), Iran Air Tours (9), LASER Airlines (9), Bulgarian Air Charter (8), Far Eastern Air Transport (8), and other carriers with smaller fleets.

Notable accidents and incidents

As of October 2015, the MD-80 series has been involved in 70 incidents, including 35 hull-loss accidents, with 1,446 fatalities of occupants.

  • On December 1, 1981, Inex-Adria Aviopromet Flight 1308, MD-81 (YU-ANA), crashed into Corsica's Mt. San Pietro during a holding pattern for landing at Campo dell'Oro Airport, Ajaccio, France. All 180 passengers and crew were killed. This was the first-ever fatal incident involving the MD-80 series in non-U.S. service.
  • 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 four-year-old girl.
  • On December 27, 1991, SAS Flight 751, MD-81 OY-KHO "Dana Viking", crash-landed at Gottröra, Sweden. In the initial climb, both engines ingested ice broken loose from the wings (although they had been properly deiced 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 into three parts. No fire occurred and all aboard survived.
  • On July 6, 1996, Delta Air Lines Flight 1288, an MD-88, attempting to take off from Pensacola Regional Airport experienced an uncontained, catastrophic turbine engine failure that caused debris from the front compressor hub of the number one left engine to penetrate the left aft fuselage. The penetrating debris left two passengers dead and two severely injured; all were from the same family. The pilot aborted takeoff and the airplane stopped on the runway.
  • 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 passengers and crew on board were killed. Following the crash, an 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, a 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, plus the ground movement radar that was inoperative at the time of the accident. The SAS crew had no role in causing the accident.
  • On May 7, 2002, China Northern Airlines Flight 6136, an MD-82, from Beijing to Dalian, crashed into Dalian Bay near Dalian, after the pilot reported "fire on board". All 112 people on board were killed. Investigators determined that the fire had been set by a suicidal passenger.
  • On November 30, 2004, Lion Air Flight 538, an MD-82, crashed on landing at Adi Sumarmo Airport in Surakarta, Indonesia, and overran the end of the runway, causing the death of 25 passengers and crew.
  • 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 applied reverse thrust, although the reversers were 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 (2,100 m) on the approach end of Runway 10. No one was killed, but the aircraft sustained $3 million in damage.
  • On March 16, 2007, a Kish Air MD-82, registration LZ-LDD leased from Bulgarian Air Charter was damaged beyond repair in a hard landing accident in Kish, Iran. There were no fatalities.
  • On September 16, 2007, One-Two-GO Airlines Flight 269, an MD-82, crashed at the side of the runway and exploded after an apparent attempt to execute a go-around in bad weather at Phuket International Airport in Phuket, Thailand. Eighty-nine of the 130 passengers and crew on board were killed.
  • On November 30, 2007, Atlasjet Flight 4203, an MD-83, crashed in the southwestern province of Isparta, Turkey, killing all 57 passengers and seven crew. The cause of the crash was attributed to pilot spatial disorientation.
  • Between March 26 and March 27, 2008 and then again between April 8 and April 12, 2008, an FAA safety audit of American Airlines forced the airline to ground its entire fleet of MD-80 series aircraft (approximately 300), to inspect the aircraft's hydraulic wiring. American was forced to cancel nearly 2,500 flights in March and over 3,200 in April. In addition, Delta Air Lines inspected its own MD-80 fleet to ensure its 117 MD-80s were also operating within regulation. This prompted Delta to cancel 275 flights.
  • On August 20, 2008, Spanair Flight 5022, MD-82 registration EC-HFP, from Madrid's Barajas Airport crashed shortly after takeoff on a flight to Las Palmas de Gran Canaria in the Canary Islands. The MD-82 had 162 passengers and ten crew on board, of whom 18 survived. The crash was caused by attempting to take off with the flaps and slats retracted. The flight crew omitted the "set flaps and slats" item in both the After Start checklist and the Takeoff Imminent checklist.
  • On November 19, 2009, Compagnie Africaine d'Aviation Flight 3711, MD-82 9Q-CAB, overran the runway on landing at Goma International Airport, and suffered substantial damage. The overrun area was contaminated by solidified lava.
  • On June 21, 2010, Hewa Bora Airways Flight 601, MD-82 9Q-COQ, burst a tire on take-off from N'djili Airport, Kinshasa, Democratic Republic of the Congo. Hydraulic systems and port engine were damaged and the nose gear did not lower when the aircraft returned to N'djili. All 110 people on board escaped uninjured. The airline blamed the state of the runway for the accident, but investigators found no fault with the runway.
  • On January 24, 2012, Swiftair Flight 94, MD-83 registration EC-JJS, suffered a wingtip strike while landing at Kandahar Airport, Afghanistan. Although there were no injuries to the 92 passengers and crew on board, the starboard wing sustained a broken main spar and the aircraft was damaged beyond economic repair. It was consequently scrapped at Kandahar.
  • On June 3, 2012, Dana Air Flight 992, MD-83 registration 5N-RAM, crashed into a two-story building in Lagos, Nigeria, caused by engine failure. All 153 passengers and crew on board were killed, as well as 10 on the ground.
  • On July 24, 2014, Air Algérie Flight 5017, registration EC-LTV, a scheduled flight from Ouagadougou, Burkina Faso, to Algiers, Algeria operated with an MD-83 leased from Swiftair, with 110 passengers and six crew from 15 nationalities on board crashed southeast of Gossi, Mali about 50 minutes after take off. All 116 passengers and crew were killed.
  • On March 5, 2015, Delta Air Lines Flight 1086 skidded off the runway on landing at La Guardia Airport, New York in snowy weather. The MD-88 operating the flight, N909DL, was severely damaged.

    FAQ

    I don't see my comments any more!

    Please note that each page has it's own comment entry. So, if you enter a comment i.e. on the B-747, you will only see it on that related page.

    General comments are accessed via the "BLOG En" button.

    Comments are moderated, so please allow some delay before they appear, specially if you are outside Europe.

    Menus are developing below the page, because they are too long!

    But they remain accessible, for example by scrolling the mouse wheel, or with your finger (on the menu) on a smartphone or tablet.

    I see adds on all videos.

    Use a good free add remover software.

    The site is loading random pages at startup.

    We think it is a good way to bring back the memory of aircraft, persons or events sometimes quite forgotten.

    HELP PAGE

    Why this site?

    Discovery

    This website is dedicated to one's aeronautical passion (which I hope we share) and was realised mainly as an educationnal tool. Knowing that, you'll notice that each new visit brings random topics for the purpose of making new discoveries, some achievements or characters certainly not deserving the oblivion into which they have sometimes fallen.

    By these pages, we also want to pay tribute to all those who gave at one time or another, their lives or health in the name of freedom, aeronautical security or simply our comfort.

    Centralisation

    Internet is full of websites dedicated to aviation, but most are dedicated to subjects or periods that are very limited in space or time. The purpose of this site is to be as general as possible and thus treats all events as well as characters of all stripes and times while putting much emphasis on the most significant achievements.

    The same years saw birth of technologies like photography and cinema, thus permitting illustration of a large part of important aeronautical events from the start. Countless (and sometimes rare) media recently put online by enthousiasts finally give us access to these treasures, but the huge amount of information often makes things a little messy. A centralization effort is obviously most needed at this level.

    All persons who directly or indirectly contributed to the achievement or posting of such documents are here gratefully acknowledged.

    General

    Fluid website

    This site automatically fits the dimensions of your screen, whether you are on a desktop computer, a tablet or a smartphone.

    Bilingual website

    You can change the language by clicking on the flag in the upper left or via "Options" in the central menu. Of course, the videos remain in the language in which they were posted ...

    Browser compatibility

    The site is not optimized, or even designed to run on older browsers or those deliberately deviating from standards. You will most probably encounter display issues with Internet Explorer. In this case, it is strongly recommended installing a modern (and free!) browser that's respecting the standards, like Firefox, Opera, Chrome or Safari.

    Cookies and Javascript

    This site uses cookies and JavaScript to function properly. Please ensure that your browser is configured accordingly. Neither of these technologies, or other means shall in no case be used on the Site for the retention or disclosure of personal information about its Visitors. See the "Legal" page for more on this subject.

    Website layout

    Left menus

    Because of the lack of space on smartphones and small tablets, these menus are hidden. Everything is nevertheless accessible via the main menu option, located between the video and photo sections. This menu is placed there for compatibility reasons with some browsers, which play the videos over the menus.

    "Search" and "Latest" :
    The link "In Titles" restricts the search to the titles of different forms. Use this option if you are looking for a plane, a constructor, a pilot or a particular event that could have been treated as a subject.

    The link "In Stories" will bring you to a search in all texts (the "Story" tab) and will take more time. The search term will appear highlighted in green when opening the corresponding story.

    Would you believe, "Timeline" will show all subjects in chronological order.

    "Random" will reload the entire page with a new random topic.

    The bottom section keeps you abreast of the latest five entries. New topics are added regularly. Don't hesitate to come visit us often : add bookmark.

    Blogs and Comments central section

    Under the photos section comes the comments tabs window :

    You can enter general comments in your own language via one of the two buttons on the left (BLOG EN and BLOG FR). Note that these buttons are accessible regardless of the language to allow some participation in the other language.

    All comments are subject to moderation and will be published only if they comply with the basic rules of decorum, while remaining relevant to the purpose of this site.

    The third tab allows you to enter comments on the shown topic and is bilingual. Personal anecdotes, supplements and other information questions will take place here.

    The "Story" tab shows the explanatory texts. They are most often taken from Wikipedia, a site where we participate regularly.

    The "Data" tab is reserved for list of features and specifications.

    Right menus

    On a smartphone, the lack of space is growing and this menu is moved to the bottom of the page to give priority to videos and pictures.

    The top right icons are links to videos posted by third parties (on their own responsabilities) or by ourselves. The link below these icons will take you to the channel of the one who posted the video. Feel free to suggest other videos if you think they are of some interest (Use the BLOG button or the "Contact" link).
