Boeing 737 MAX

The Boeing 737 MAX is a series of narrow-body aircraft developed by Boeing Commercial Airplanes as the fourth generation of the 737, succeeding the 737 Next Generation with more efficient CFM International LEAP engines, split-tip winglets and structural modifications. The programme was announced in August 2011, first flew in January 2016 and was certified by the FAA in March 2017, with the first delivery, a MAX 8, to Malindo Air in May 2017. It has four main variants, the MAX 7, 8, 9 and 10, plus the high-density MAX 200, seating 138 to 204 passengers over 3,300 to 3,850 nautical miles. Two fatal accidents, Lion Air Flight 610 in October 2018 and Ethiopian Airlines Flight 302 in March 2019, were linked to the MCAS flight control software and led to a worldwide grounding from March 2019 to November 2020. After software changes and revised pilot training the type was cleared to return to service.
