The Boeing 737 MAX is the fourth generation of the Boeing 737, a narrow-body airliner manufactured by Boeing. It is based on earlier 737 designs, with more efficient CFM International LEAP-1B engines, aerodynamic changes including its distinctive split-tip winglets, and airframe modifications. The 737 MAX series has been offered in four variants, offering 138 to 204 seats in typical two-class configuration and a 3,215 to 3,825 nmi range.
About Boeing 737 MAX in brief
The Boeing 737 MAX is the fourth generation of the Boeing 737, a narrow-body airliner manufactured by Boeing. It is based on earlier 737 designs, with more efficient CFM International LEAP-1B engines, aerodynamic changes including its distinctive split-tip winglets, and airframe modifications. The 737 MAX series has been offered in four variants, offering 138 to 204 seats in typical two-class configuration and a 3,215 to 3,825 nmi range. 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. The airplane’s Maneuvering Characteristics Augmentation System had malfunctioned on both flights. Boeing suspended production in January 2020 with approximately 400 MAX airplanes awaiting delivery. Production resumed in May 2020 at a low rate. On November 18, 2020, the FAA cleared the MAX to return to service once necessary design modifications have been made. The company agreed to pay a criminal monetary amount exceeding USD 2.5 billion to settle a criminal charge of fraud against Boeing relating to evaluation of the 737MAX. Boeing abandoned the development of a new design for the 737 in 2011. Boeing expected the 737 Max to meet or exceed the range of the Airbus A320neo family. On July 20, 2011, American Airlines announced an order for 460 narrowbody jets including 130 A320ceos and 130 A 320neos, and intended to order 100 re-engined 737s with CFM LEAPs, pending Boeing confirmation.
The order broke Boeing’s monopoly with the airline and forced Boeing into a re-Engined 737. The development of the new 737 was estimated at US$10–12billion at the time. Southwest Airlines was signed up as the launch customer in 2011, with a backlog of 1,029 units since its launch, setting an order record for a new commercial airliner. In January 2012, Boeing predicted that the cost of the program would be twice that of the A320NEo program, and could have been well over the US$2bn internal target and over US$4bn external target. Boeing’s CEO Jim McNerney maintained \”We’re going to do a new airplane. \” In March 2011, BCA President James Albaugh told participants of a trade meeting the company was not sure about a 737 re-engine, like Boeing CFO James A. Bell stated at an investor conference the same month. On August 30,2011, Boeing’s board of directors approved the launch of the re- Engined 737, expecting a fuel burn 4% lower than the A32neo. On December 1, 2010, Airbus launched the Airbus A320nee family to improve fuel burn and operating efficiency with new engines: the CFM international LEAP and Pratt & Whitney PWR1000G. The first delivery was a MAX 8 in May 2017, to Malindo Air, with whom it commenced service on May 22, 2017. The 737 MAX 9 is intended to replace the 737-700, -800, and -900 respectively, and a further stretched 737 MAX 10.
