MAX. The MAX is a family of narrow-body airliners developed by Boeing Commercial Airplanes as the fourth generation of the Boeing 737, succeeding the Boeing 737 Next Generation (NG). It was designed to compete with the Airbus A320neo family and entered service in 2017. The aircraft incorporates more efficient CFM International LEAP engines and aerodynamic improvements but was globally grounded between 2019 and 2020 following two fatal crashes.

History

The program was launched in August 2011 by Boeing in response to the market success of the rival Airbus A320neo. Key airline customers like American Airlines, which had placed a major order with Airbus, provided the impetus for the development. The first model, the MAX 8, performed its maiden flight from Boeing Field in 2016. The aircraft's development and subsequent service were profoundly impacted by the accidents of Lion Air Flight 610 and Ethiopian Airlines Flight 302, leading to a worldwide grounding by regulators including the Federal Aviation Administration and the European Union Aviation Safety Agency.

Design and development

The primary design goal was to improve fuel efficiency over the preceding Boeing 737 Next Generation by approximately 14-20%. This was achieved primarily through the installation of larger, more efficient CFM International LEAP-1B engines, which required aerodynamic changes such as distinctive chevron-style nacelles and modifications to the winglet design. A key and controversial new software system, the Maneuvering Characteristics Augmentation System (MCAS), was implemented to handle the aircraft's altered flight characteristics. The flight deck features large Rockwell Collins displays similar to the Boeing 787 Dreamliner.

Operational history

The first delivery was to Malindo Air (a subsidiary of Lion Air) in 2017, with the airline commencing commercial flights that same year. Major operators like Southwest Airlines, American Airlines, and Ryanair integrated the type into their fleets. Following the two crashes in 2018 and 2019, all MAX aircraft were grounded globally for nearly two years. The return to service, beginning in late 2020 after extensive software updates and pilot training revisions mandated by the Federal Aviation Administration, was a gradual process involving regulators worldwide, including Transport Canada and the Civil Aviation Administration of China.

Variants

The family consists of four main models, each targeting different range and capacity segments of the market. The MAX 7 is the shortest variant, intended to replace the Boeing 737-700. The MAX 8 is the base and most common model, with a higher-capacity MAX 200 version for Ryanair. The stretched MAX 9 and the largest MAX 10 compete directly with the Airbus A321neo. A business jet version, the BBJ MAX, is also offered.

Specifications (MAX)

Specifications are for the baseline MAX 8 model. It is typically configured for 162 to 210 passengers in a two-class layout. The aircraft has a length of 39.5 meters, a wingspan of 35.9 meters, and a height of 12.3 meters. It is powered by two CFM International LEAP-1B turbofan engines, each producing up to 29,000 pounds of thrust. Maximum takeoff weight is 82,190 kg, with a range of approximately 6,570 kilometers. Its cruise speed is Mach 0.79, comparable to other modern airliners like the Airbus A320neo.

Operators

As of 2024, the largest operator is Southwest Airlines, which has hundreds on order. Other major airline customers in North America include United Airlines, American Airlines, and Air Canada. In Europe, Ryanair is a significant customer for the high-density MAX 200, while Flydubai is a key operator in the Middle East. In Asia, carriers like SpiceJet and Lion Air operate the type, though some, like China Southern Airlines, have only recently resumed deliveries following the grounding.
