The worldwide Boeing 737 MAX grounding occurred on 13 March 2019 following the crash of Ethiopian Airlines flight 302. The crash of ET302 was the second crash of a 737 MAX following Lion Air 610 the previous October. Both crashes implicated the Maneuvering Characteristics Augmentation System (MCAS), a flight control system unique to the 737 MAX. Initially expected to last weeks, the grounding is now projected to stretch more than a year as Boeing works on a revision of MCAS and associated changes to the MAX. Boeing suspended 737 MAX production in January 2020 and on 21 January announced it expects return to service to ‘begin during mid-2020’.
