Boeing 737 MAX

The 737 MAX represents the fourth generation of the Boeing 737, following on from the 737NG Series.It was developed in response to a decision by Airbus to improve and re-engine its A320 family.Key to the development of the 737 MAX was the more efficient CFM LEAP-1B engine, which promised improvements in fuel consumption and operating costs.The 737 MAX is offered in four variants and the first flight of the MAX Series involved a MAX 8 on 29 January 2016, and entered into service on 22 May 2017 with Malindo Air.By the end of 2018, 4,300 aircraft had been ordered by 95 airlines.However, two fatal incidents involving MAX 8 aircraft occurred in 2018 and 2019, leading to a worldwide grounding of all MAX aircraft from March 2019 to November 2020, and the cancellation of many orders.The main cause of the crashes was a malfunctioning automated flight control system called MCAS (Manoeuvring Characteristics Augmentation System).Four key design changes to the 737 MAX and airline training programme
