[106] The two-spool design has a low-pressure section comprising the fan and three booster stages driven by five axial turbine stages and a high-pressure section with a 10-stage axial compressor driven by a two-stage turbine. [92], On August 19, 2020, Boeing announced that it had received new orders for the 737 MAX for the first time in 2020. As we can see, the range of the plane goes down the bigger it is (until you get to the last extended range model, the 737-900ER). The aircraft was four months old at the time. The 737 MAX family is designed to offer the greatest flexibility, reliability and efficiency in the single-aisle market. [90] On May 27, 2020, Boeing resumed 737 MAX production at a low production rate, which it expected to be ramped up according to customer deliveries, towards 31 monthly in 2021. Malaysia Airlines has signed a deal with Aircraft manufacturer Boeing to purchase fifty of their latest aircraft, the Boeing 737 MAX worth $5.5 billion dollars at current list prices. [138] An order with Ryanair for 100 aircraft was finalized in December 2014. [99], The split tip wingtip device is designed to maximize lift while staying in the same ICAO Aerodrome reference code letter C gates as current 737s. Driven by the existing retraction system, a shrink-link mechanical linkage mechanism at the top of the leg, inspired by carrier aircraft designs, allows the gear to be drawn in and shortened while being retracted into the existing wheel well. Bernstein Research predicted in January 2012, that this cost would be twice that of the Airbus A320neo. [29] Fuel consumption is reduced by 14% from the 737NG. Compared to STS, MCAS has greater authority and cannot be disengaged with the aft and forward column cutout switches. [37], A new spar-assembly line with robotic drilling machines should increase throughput by 33%. Using electric pitch trim will only pause MCAS for 5s; to deactivate it you need to switch off the STAB TRIM CUTOUT switches. [91] Transport Canada and EASA each concluded their own independent recertification flights in late August and early September 2020. 387 delivered to customers as of March 2019, Airframe only: $1–1.8 billion; including engine development: $2–3B, 28–29 in (71–74 cm) in high density, 29–30 in (74–76 cm) in economy, 36 in (91 cm) in business, 117 ft 10 in / 35.92 m span, 1,370 sq ft (127 m, 6,820 USgal / 25,816 L – 45,694 lb / 20,730 kg (no, *Overlapping production times like between the 747-400 and the 747-8 have been decided in favor of newer models, This page was last edited on 8 January 2021, at 20:01. [139] The variant is designated 737-8200. – discuss] as an alternative to the MAX 7 to replace its fleet of over 400 737-700s, with deliveries from 2025. Las dudas sobre la seguridad de los aviones Boeing 737 Max hizo que la compañía difundiera cientos de mensajes internos como muestra de transparencia. Thanks to the new, larger 15-inch screens, pilots get more information with less effort. [28], In March 2010, the estimated cost to re-engine the 737 according to Mike Bair, Boeing Commercial Airplanes' vice president of business strategy & marketing, would be US$2–3 billion including the CFM engine development. Site Terms | Privacy and Cookie Statement | Ad Choices On November 18, 2020, the FAA cleared the MAX to return to service once necessary design modifications have been made. The new winglet is 9 ft 6 in (2.90 m) high. In early 2017, a new -8 was valued at $52.85 million, rising to below $54.5 million by mid 2018. How far are you going? [173], The BBJ MAX 8 and BBJ MAX 9 are proposed business jet variants of the Boeing 737 MAX 8 and 9 with new CFM LEAP-1B engines and advanced winglets providing 13% better fuel burn than the Boeing Business Jet; the BBJ MAX 8 will have a 6,325 nmi (11,710 km) range and the BBJ MAX 9 a 6,255 nmi (11,580 km) range. [75] [98], In mid-2011, the objective was to match the A320neo's 15% fuel burn advantage. Whenever. [77][14] The 737 MAX program was Boeing's largest source of profit. Cumulative Boeing 737 MAX orders and deliveries, The global fleet of nearly 400 737 MAXs flew 500,000 flights from March 2017 to March 2019, and experienced two fatal accidents for an accident rate of four accidents per million flights when it was grounded. As of November 2020, the Boeing 737 MAX had a backlog of 3,290.[10]. The reason given is: the Boeing 737 MAX is grounded and deliveries have been delayed. The MAX probes on the LHS. Aeroméxico Places 737 MAX Back Into Service. [93], On October 28, 2020, Boeing indicated that it expected to deliver about half of the 450 stockpiled aircraft in 2021, and the majority of the remainder in 2022, noting that some of these aircraft will need to be re-marketed and potentially reconfigured.

[30] The CFM56 bypass ranges from 5.1:1 to 5.5:1. In March 2019, the 737 MAX was grounded worldwide after 346 people died in two crashes, Lion Air Flight 610 and Ethiopian Airlines Flight 302. Larger Engines. [136][137] Three of eight galley trolleys are removed to accommodate more passenger space. [102] Boeing plans no major modifications for the 737 MAX flight deck, as it wants to maintain commonality with the 737 Next Generation family. [6], On November 18, 2020, the FAA announced that the MAX had been cleared to return to service. Now let us compare it to the 737 MAX series (the fourth generation of Boeing 737). [105], In 2011, the Leap-1B was initially 10–12% more efficient than the previous 156 cm (61 in) CFM56-7B of the 737NG. The Boeing 737 MAX groundings have had a deep financial effect on the aviation industry and a significant effect on the national economy of the United States. Statement: Boeing Responds to FAA Approval to Resume 737 MAX Operations Changes to the 737 MAX Global regulators and aviation organizations from around the world collaborated to allow the airplane to safely return to service. The 737 MAX builds on the strengths of today's Next-Generation 737 by incorporating the latest-technology to deliver the highest efficiency, reliability and passenger comfort in the single-aisle market. [113] The new nacelles being larger and more forward possess aerodynamic properties which act to further increase the pitch rate. The 737 Max crisis has stymied Boeing's growth. [48], The first flight took place on January 29, 2016, at Renton Municipal Airport,[49] nearly 49 years after the maiden flight of the original 737-100, on April 9, 1967. [22] As this sale included a Most-Favoured-Customer Clause, Airbus has to refund any difference to American if it sells to another airline at a lower price, so the European manufacturer cannot give a competitive price to competitor United Airlines, leaving it to a Boeing-skewed fleet. Lion Airlines Boeing 737 (MAX); PK-LQP Tanjung Karawang, West Java, Republic of Indonesia 29 October 2018", "Boeing issues operational manual guidance to airlines following Lion Air crash", "Ethiopian Airlines: 'No survivors' on crashed Boeing 737", "Ethiopian Airlines Boeing 737 MAX involved in fatal crash", "Ethiopian Airlines crash: inquiry to explore how 'excellent' pilot was unable to avert disaster", "Investigators find 2nd piece of key evidence in crash of Boeing 737 Max 8 in Ethiopia", "Ethiopian Airlines crew 'followed rules, unable to control jet, "When Will the Boeing 737 MAX Fly Again? The 737 MAX series has been offered in four variants, offering 138 to 204 seats in typical two-class configuration[9] and a 3,215 to 3,825 nmi (5,954 to 7,084 km) range. The first aircraft was delivered from the facility to Air China on December 15, 2018. [164] Boeing ended the 2017 Paris Air Show with 361 orders and commitments, including 214 conversions, from 16 customers,[165] including 50 orders from Lion Air. [125] Lion Air is the launch customer with an order for 201 in February 2012. In the following eighteen months, Boeing redesigned the computer architecture that supported MCAS, while investigations faulted aircraft design and certification lapses. [68] Moody's also warned the production halt would have wide and harmful impact to the whole aerospace and defense supply chain and, if and when production resumes, the ramp up would be slower than previously anticipated, as suppliers have to make adjustments to cost structures built for planned record output on the 737 program. [191][192] People familiar with the investigation reported that during a flight piloted by a different crew on the day before the crash, the same aircraft experienced a similar malfunction but an extra pilot sitting in the cockpit jumpseat correctly diagnosed the problem and told the crew how to disable the malfunctioning Maneuvering Characteristics Augmentation System (MCAS) flight-control system. Look for: Carbon fiber fan blades with a titanium leading edge, chevrons at the rear of the engine casing and a larger engine that sits higher up and farther forward on the wing. [132], The first variant developed in the 737 MAX series, the MAX 8 replaces the 737-800 with a longer fuselage than the MAX 7. [186][187] By November 30, 2020, orders had declined to 4,039 and the backlog to 3,290 after accounting adjustments recognizing orders unlikely to be filled.[5][188]. [202], Aircraft of comparable role, configuration, and era. [151] It was presented at the 2017 Paris Air Show. The delivery rate will also condition the production rate for new aircraft, to avoid compounding the problem. [159] Boeing predicts a 5% lower trip cost and seat cost compared to the A321neo. [30] New struts and nacelles for the heavier engines add bulk, the main landing gear and supporting structure are beefier, and fuselage skins are thicker in some places for a 6,500 lb (2,900 kg) increase to the MAX 8's empty aircraft weight. [38] As production standard, the 737 MAX features the Boeing Sky Interior with overhead bins and LED lighting based on the Boeing 787's interior. [152], Boeing 737-9 flight tests were scheduled to run through 2017, with 30% of the -8 tests repeated; aircraft 1D001 was used for auto-land, avionics, flutter, and mostly stability-and-control trials, while 1D002 was used for environment control system testing. [125], Production on the first 65-foot-long (20 m) wing spar for the 737-7 began in October 2017. That’s another way you can tell that you’re on a 737 MAX. Before the aircraft can resume service, repairs must be implemented per a forthcoming airworthiness directive from the FAA. All Rights Reserved. Malaysia Airlines Bhd. The first delivery was a MAX 8 in May 2017, to Malindo Air, with whom it commenced service on May 22, 2017. Overview The Maneuvering Characteristics Augmentation System (MCAS) flight control law was designed and certified for the 737 MAX to enhance the pitch stability of the airplane – so that it feels and flies like other 737s. During that time, FAA employees worked diligently to identify and … [21] The order broke Boeing's monopoly with the airline and forced Boeing into a re-engined 737. It succeeds the Boeing 737 Next Generation (NG). [114], The 737-700, -800 and -900ER, the most widespread versions of the previous 737NG,[5] are succeeded by the 737 MAX 7, MAX 8 and MAX 9, respectively[115] (FAA type certificate: 737-7, -8, and -9[51]). [5] The MAX 7 seems to have fewer than 100 orders among over 4,300 MAX total sales. [178], American Airlines was the first disclosed customer. [149], The 737 MAX 9 will replace the 737-900 and has a longer fuselage than the MAX 8. [55], After one year of service, 130 MAXs had been delivered to 28 customers, logging over 41,000 flights in 118,000 hours and flying over 6.5 million passengers. [100] A MAX 8 with 162 passengers on a 3,000 nmi (5,600 km) flight is to have up to a 1.8% better fuel burn than a blended-winglet-equipped aircraft and 1% over 500 nmi (930 km) at Mach 0.79.[100]. [2] Norwegian Air subsidiary Norwegian Air International was the second airline to put a 737 MAX into service, when it performed its first transatlantic flight with a MAX 8 named Sir Freddie Laker on July 15, 2017, between Edinburgh Airport in Scotland and Bradley International Airport in the US state of Connecticut, followed by a second rotation from Edinburgh to Stewart Airport, New York. The Boeing Archives Presents Video Series. | OneTrust Cookie Settings. [147], On December 3, 2020, Ryanair ordered 75 MAX 8-200s, increasing its order book to 210 aircraft, the first large order since the grounding, for a list value of $7bn while the true value is estimated at $3bn or less. Most regulators raised safety concerns and grounded the aircraft before March 13, when the U.S. Federal Aviation Administration (FAA) received evidence of accident similarities and grounded it. [65][66][67] The rising costs also led Moody's to downgrade Boeing's credit rating. The split winglet added 1–1.5%, a re-lofted tail cone 1% more. [16], On December 1, 2010, Boeing's competitor, Airbus, launched the Airbus A320neo family to improve fuel burn and operating efficiency with new engines: the CFM International LEAP and Pratt & Whitney PW1000G. [63][64] MCAS will turn the trim wheel. [11] The airplane's Maneuvering Characteristics Augmentation System (MCAS) had malfunctioned on both flights. [30], The 737 MAX extended spoilers are fly-by-wire controlled. [145], Besides Ryanair, VietJet Air is also one of the few customers of the MAX 200 variant with an order of 100 airplanes placed in May 2016. [140], In mid-November 2018, the first of the 135 ordered by Ryanair rolled out, in a 197-seat configuration. Boeing is committed to serving and supporting its customers. The 737 class is a workhorse for airlines worldwide, and the single-aisle 737 Max has been Boeing’s best-selling plane ever. [32], On August 13, 2015, the first 737 MAX fuselage completed assembly at Spirit Aerosystems in Wichita, Kansas, for a test aircraft that would eventually be delivered to launch customer Southwest Airlines. To summarise; MCAS will trim the Stabilizer down for up to 9.26 seconds (2.5 deg nose down) and pause for 5 seconds and repeat if the conditions (high angle of attack, flaps up and autopilot disengaged) continue to be met. [77] At the time of the grounding, the 737 MAX had 4,636 unfilled orders[185] valued at an estimated $600 billion. MCAS is designed to activate in manual flight, with the airplane's flaps up, at an elevated Angle of Attack (AOA). [61] Boeing planned to deliver at least 50 to 75 aircraft in 2017, 10–15% of the more than 500 737s to be delivered in the year. [175] The MAX BBJ 8 first flew on April 16, 2018, before delivery later the same year, and will have a range of 6,640 nmi (12,300 km) with an auxiliary fuel tank. [25] Boeing abandoned the development of a new design. [1] The first MAX 8, 1A001, was used for aerodynamic trials: flutter testing, stability and control, and takeoff performance-data verification, before it was modified for an operator and delivered. The Boeing 737 Max 8, the model involved in the two deadly crashes, is the newer successor to the Boeing 737 Next Generation line of aircraft. The last pre-suspension fuselages entered final assembly in early January 2020. Boeing found foreign object debris in the fuel tanks of 35 of 50 grounded 737 MAX aircraft that were inspected, and is to check the remainder of the 400 undelivered planes. The Panamanian carrier, which is gearing up for MAX flights, added its seventh Boeing 737 MAX 9 aircraft on Tuesday. The new series was publicly announced on August 30, 2011. [82] Industry observers began to question if Boeing's projection of record production rate of 57 per month would ever be reached. This plane is a significant part of the airline’s future fleet plans. Boeing estimated it would cost an additional $6.3 billion to produce the remaining 737 MAX program, $4 billion for "future abnormal costs" as production restarted, plus an estimated $8.3 billion for concessions and compensation to customers. The 737 MAX 7, MAX 8 (including the denser, 200–seat MAX 200), and MAX 9 are intended to replace the 737-700, -800, and -900 respectively, and a further stretched 737 MAX 10. [144] In November 2019, Ryanair informed its pilots that, due to an unspecified design issue with the additional over-wing exit doors, it did not expect to receive any MAX 200s until late April or early May 2020, with "at best" 10 aircraft in service for the peak summer season. One vestige is its 2016 deal for 25 737 MAX aircraft and a further 25 options, at the time a logical replacement for its 737 NG fleet, which today numbers 48. [87] By early April, the COVID-19 pandemic led Boeing to shut down its other airliner production lines[88] and further delayed recertification of the MAX. [157], In October 2016, Boeing's board of directors granted authority to offer the stretched variant with two extra fuselage sections forward and aft with a 3,100 nautical miles (3,600 mi; 5,700 km) range reduced from 3,300 nautical miles (3,800 mi; 6,100 km) of the -9. The fan was widened from 61 in (150 cm) to 69.4 in (176 cm) by raising the nose gear and placing the engine higher and forward. This aircraft sets new standards in fuel efficiency and performance, increasing its range by 19 percent to over 3,850 nautical miles. [155] In early 2017, Boeing showed a 66 in (1.7 m) stretch to 143 feet (44 m), enabling seating for 230 in a single class or 189 in two-class capacity, compared to 193 in two-class seating for the A321neo. [83] In early January 2020, an issue was discovered in the software update, further delaying the return to service. [120], Originally based on the 737-700, Boeing announced the redesign of the MAX 7 derived from the MAX 8 at the July 2016 Farnborough Air Show, accommodating two more seat rows than the 737-700 for 138 seats, up 12 seats. The larger engine is cantilevered ahead of and slightly above the wing, and the laminar flow engine nacelle lipskin is a GKN Aerospace one-piece, spun-formed aluminum sheet inspired by the 787. Boeing plans to improve its range from 3,510 nmi (4,040 mi; 6,500 km) to 3,605 nmi (4,149 mi; 6,676 km) after 2021. A typical flight reaches an altitude of 25,000 feet in about 10 minutes. After the 737 Max is approved to return to service, it will be at least weeks, if not months, before any of them are carrying paying passengers once … [30] Aviation Partners offers a similar "Split-Tip Scimitar" winglet for previous 737NGs. [174] The BBJ MAX 7 was unveiled in October 2016, with a 7,000 nmi (12,960 km) range and 10% lower operating costs than the original BBJ while being larger. [30] The 41:1 overall pressure ratio, increased from 28:1, and advanced hot-section materials enabling higher operating temperatures permit a 15% reduction in thrust specific fuel consumption (TSFC) along with 20% lower carbon emissions, 50% lower nitrogen-oxide emissions, though each engine weighs 849 lb (385 kg) more at 6,129 lb (2,780 kg). [135], In September 2014, Boeing launched a high-density version of the 737 MAX 8, the 737 MAX 200, named for seating for up to 200 passengers in a single-class high-density configuration with slimline seats; an extra pair of exit doors is required because of the higher passenger capacity. [56], During the certification process, the FAA delegated many evaluations to Boeing, allowing the manufacturer to review their own product. [62], In 2019, Moody's had estimated Boeing's operating margin to be US$12–15 million for each 737 Max 8 at its list price of $121.6 million, although the list price is usually discounted 50-55% in practice. Boeing predicts the MAX 7 to carry 12 more passengers 400 nmi (740 km) farther than A319neo with 7% lower operating costs per seat. Presented in 18 languages with an interactive library. [7] The MAX development cost could have been well over the US$2 bn internal target and closer to US$4 bn. [53] After completing 2,000 test flight hours and 180-minute ETOPS testing requiring 3,000 simulated flight cycles in April 2017, CFM International notified Boeing of a possible manufacturing quality issue with low pressure turbine (LPT) discs in LEAP-1B engines. The Guardian reported that Boeing referred to the airplane as a Boeing 737-8 in a move away from the Boeing 737 MAX branding. The airplane was to have a similar fuselage but made from composite materials developed for the Dreamliner. [71] Boeing has seen more than 1000 order cancelations since the grounding in March 2019. PT. [141] It was first flown from Renton on January 13, 2019,[142] and was due to enter service in April 2019, with another four MAX 200s expected later in 2019,[143] though these deliveries were deferred while the MAX is grounded; Ryanair has stated that it intends to place more orders once flights resume. The FAA grounding order was lifted on November 18, 2020;[71] all aircraft must be repaired to comply with various airworthiness directives. [95] As of August 2018[update], assembly was underway with a first flight planned for late 2019. De hecho, antes de que el 737 MAX se quede en tierra, los Pilotos de Southwest completaron casi 40,000 vuelos en la aeronave, lo que equivale a más de 89,000 horas de vuelo. The modest stretch of the MAX 10 enables the aircraft to retain the existing wing and CFM Leap 1B engine from the MAX 9 with a trailing-link main landing gear as the only major change. FAA Statement on Boeing 737 Max Return to Service. It took its maiden flight on January 29, 2016 and was certified by the U.… Bell stated at an investor conference the same month. First, let’s look at the third generation 737 aircraft side by side. This was the first fatal aviation accident and first hull loss of a 737 MAX. Visit Malaysia Airlines 737 MAX The 737 MAX optimizes the market-leading strengths of the highly successful Next-Generation 737 to assure operators of competitive success far into the future. 737 MAX has it, with the innovative Boeing Sky Interior — a design utilizing modern-sculpted sidewalls, customizable LED lighting, and other improvements to both form and function.
