75-460: There has been no progress as The YPX was to have seated between 100 and 150 passengers, and would thus have been competitive with the smaller Boeing 737 and Airbus A320 family jets on short haul routes. The engine choice had not been made at the time its development was halted. Entry into service was expected to have been somewhere around 2015. However, no prototype has been built. Kawasaki had hoped to cut fuel costs of up to 15% in comparison to

150-504: A glass cockpit , and upgraded and redesigned interior configurations. The series includes four variants, the –600/–700/–800/–900, seating between 108 and 215 passengers.

On 27 March 2020 the Brazilian regulatory bodies gave the nihil obstat to the purchase and sale of flights started on 14 April 2020. thus ending the partnership. On 8 June 2021 Gol Linhas Aéreas announced

4125-520: The new variants, the −600 series, is identical in size to the −500, launching in December 1997 with an initial flight occurring January 22, 1998; it was granted FAA certification on August 18, 1998. The flight test program used 10 aircraft: 3 -600s, 4 -700s, and 3 -800s. In 2004, Boeing offered a Short Field Performance package in response to the needs of Gol Transportes Aéreos , which frequently operates from restricted airports. The enhancements improve takeoff and landing performance. The optional package

4200-422: The pivoting bins, thus allowing a 737-800 to hold 174 carry-on bags . Boeing also offered it as a retrofit for older 737NG aircraft. The 737-600 was launched by SAS in March 1995, with the first aircraft delivered in September 1998. A total of 69 have been produced, with the last aircraft delivered to WestJet in 2006. Boeing displayed the 737-600 in its price list until August 2012. The 737-600 replaces

4275-471: The plant on Day 1. Electrical wiring is installed on Day 2 and hydraulic machinery on Day 3. On Day 4 the fuselage is crane-lifted and rotated 90 degrees, wings are mated to the airplane in a six-hour process, along with landing gear , and the airplane is again rotated 90 degrees. The final assembly process begins on Day 6 with the installation of airline seats , galleys , lavatories , overhead bins , etc. Engines are attached on Day 8 and it rolls out of

4350-424: The purchase of MAP Linhas Aéreas from Voepass Linhas Aéreas . The transaction included 26 slots at São Paulo–Congonhas Airport belonging to MAP and Voepass.

4425-631: The same faulty components of the 737 MAX on some one hundred and thirty-three 737 NGs. From 2006, Boeing discussed replacing the 737 with a "clean sheet" design (internally named " Boeing Y1 ") that could follow the Boeing 787 Dreamliner . A decision on this replacement was postponed, and delayed into 2011. In 2011, Boeing launched the 737 MAX, an updated and re-engined version of the 737NG with more efficient CFM International LEAP -1B engines, and aerodynamic changes with distinctive split-tip winglets . The first 737 MAX performed its first flight in January 2016. The fourth generation 737 MAX supersedes

4500-477: The shortcomings of the 737-900, and to directly compete with the Airbus A321 . Up to two auxiliary fuel tanks in the cargo hold and standard winglets improved the range of the stretched jet to that of other 737NG variants, while an additional pair of exit doors and a flat rear pressure bulkhead increased maximum seating capacity to 220 passengers. Airlines may deactivate (plug) the additional exit doors if

4575-615: The slower, shorter-range 737 Classic variants into the more efficient, longer New Generation variants. In 1991, Boeing initiated development of an updated series of aircraft. After working with potential customers, the 737 Next Generation (NG) program was announced on November 17, 1993. The first NG to roll out was a 737−700, on December 8, 1996. This aircraft, the 2,843rd 737 built, first flew on February 9, 1997, with pilots Mike Hewett and Ken Higgins. The prototype 737−800 rolled out on June 30, 1997, and first flew on July 31, 1997, piloted by Jim McRoberts and again by Hewett. The smallest of

4650-487: The third generation 737NG. Split Scimitar winglets became available in 2014 for the 737-800, 737-900ER, BBJ2 and BBJ3, and in 2015 for the 737-700, 737-900 and BBJ1. These resemble the 737 MAX's split winglet, though they are not identical. Split Scimitar winglets were developed by Aviation Partners , the same Seattle-based corporation that developed the blended winglets; the Split Scimitar winglets produce up to

4725-454: The total configured capacity of the plane is 189 passengers or less. The first 737-900ER was rolled out of the Renton, Washington , factory on August 8, 2006, for its launch customer, Lion Air , an Indonesian low-cost airline . The airline received this aircraft on April 27, 2007, in a special dual paint scheme combining Lion Air's logo on the vertical stabilizer and Boeing's livery colors on

4800-547: The use of miles or miles plus money is mandatory, as well as a minimum 7-day stay at the destination. In February 2014, Air France–KLM announced it would invest $ 100 million in Gol Linhas Aéreas Inteligentes in advance of the 2014 FIFA World Cup and the 2016 Olympics . Some disagreement exists as to whether Gol is a low-cost carrier . In 2014, Gol was ranked the second-best low-cost airline in South America after Azul . Gol refers to itself as

4875-453: The −900 retains the same exit configuration of the -800, seating capacity is limited to 189, although aircraft equipped with a typical 2-class layout will seat approximately 177. The 737-900 also retains the MTOW and fuel capacity of the −800, trading range for payload. Alaska Airlines launched the 737-900 in 1997, the 737-900 made its first flight on August 3, 2000, and Alaska Airlines accepted

4950-589: Was 42 units per month in 2014, and was planned to reach rates of 47 units per month in 2017 and 52 units per month in 2018. In 2016, the monthly production rate was targeted to reach 57 units per month in 2019, even to the factory limit of 63 units later. A single airplane was then produced in the Boeing Renton Factory in 10 days, less than half what it was a few years before. The empty fuselage from Spirit AeroSystems in Wichita, Kansas , enters

5025-500: Was also adopted on the Boeing 757-300 . This improved on the previous interior of the Boeing 757-200 and the Boeing 737 Classic variants, the new interior became optional on the 757-200. In 2010, new interior options for the 737NG included the 787 -style Boeing Sky Interior.

Boeing's newer "Space Bins" can carry 50 percent more than

5100-628: Was announced that Gol would merge with Avianca to form the Abra Group , which would own both companies. Celso Ferrer became the CEO of the Brazilian airline 1 July 2022. In March 2023, Gol reduced frequencies in Fortaleza as well as cancelled the Fortaleza airline's hub. In January 2024, Gol prepared to file for Chapter 11 bankruptcy , stating that the airline has been struggling with high debt and recently hired Seabury Capital to help it in

5175-423: Was delivered to West Atlantic in April 2018. At the 2018 Farnborough Airshow , GECAS announced an agreement for 20 firm orders and 15 option orders for the 737-800BCF, raising the commitment to 50 aircraft. Total orders and commitments include 80 aircraft to over half a dozen customers. Since early 737NG aircraft become available on the market, they have been actively marketed to be converted to cargo planes via

5250-528: Was established in 2000 as Gol Transportes Aéreos S.A. and started operations on 15 January 2001 with a flight from Brasília to São Paulo. It is a subsidiary of the Brazilian conglomerate Grupo Áurea, based in Minas Gerais state , which has other transportation interests, including Brazil's largest long-distance bus company. Grupo Áurea in turn is owned by the Constantino family. Constantino Júnior

5325-455: Was issued on October 3, 2019. Of the 500 first inspected aircraft, 5% (25) had cracks and were grounded; Boeing expected to repair the first aircraft three weeks after the issuance of the directive, serving as the template for the resulting Service bulletin . Of the 810 examined aircraft over 30,000 cycles, 38 had structural cracks (4.7%), leaving 1,911 737NGs over 22,600 cycles to be inspected within their next 1,000 cycles, i.e., nearly all of

5400-603: Was later dropped. The brand Gol operates most of the flights of the network, and had aircraft configured in all-economy class, used for scheduled domestic and international operations within South America. Because of contractual obligations, between 2006 and 2009 the "new Varig" (VRG Linhas Aéreas) was obliged to purchase a minimum of 140 hours/month of services from the "old Varig" (Flex Linhas Aéreas). Therefore, at that time, some of VRG Linhas Aéreas flights operated with Gol flight numbers but were actually flown with chartered aircraft from Flex Linhas Aéreas. The agreement ceased before

5475-456: Was responsible for building the business next to the vice president of the company, David Barioni . In 2007, Gol was owned by AeroPar Participações (75.5%), Venture (17.6%), American International Group (5.4%) and Air France-KLM (1.5%). The growth in GOL's stock price made the Constantino family a member of the Forbes magazine billionaire list in 2005. In 2007, Gol was supposed to begin

5550-445: Was the 737-800, with 4,991 commercial, 191 military, and 23 corporate, or a total of 5,205 aircraft. Boeing stopped assembling commercial 737NGs in 2019 and made the final deliveries in January 2020. The 737NG is superseded by the fourth generation 737 MAX , introduced in 2017. When regular Boeing customer United Airlines bought the more technologically advanced Airbus A320 with fly-by-wire controls, this prompted Boeing to update

5625-721: Was to have a five-abreast economy cabin and an elliptical cross-section - that is, with a smoothly varying radius, rather than the old double-bubble based on two distinct radii. Economy seats would be 46 cm (18 in) wide; the aisle, 51 cm (20 in). In 2012, the Ministry of Defense and Kawasaki Heavy Industries pointed out that "a passenger aircraft based almost entirely on the XP-1 would have little marketability, and would require significant design changes that would be almost completely new, making it difficult to justify." Civilian aircraft of this class are usually twin-engine aircraft due to cost and fuel efficiency considerations, and
