The Boeing 737 MAX passenger airliner was grounded worldwide between March 2019 and December 2020 – longer in many jurisdictions – after 346 people died in two crashes, Lion Air Flight 610 on October 29, 2018, and Ethiopian Airlines Flight 302 on March 10, 2019. The U.S. Federal Aviation Administration (FAA) resisted grounding the aircraft until March 13, 2019, when it received evidence of accident similarities. By then, 51 other regulators had already grounded the plane,[2] and by March 18, 2019, all 387 aircraft in service were grounded.

The Boeing 737 MAX was initially certified in 2017 by the U.S. Federal Aviation Administration (FAA) and the European Union Aviation Safety Agency (EASA). However, global regulators grounded the plane in 2019 following two fatal crashes of Lion Air Flight 610 and Ethiopian Airlines Flight 302. Both crashes were linked to the Maneuvering Characteristics Augmentation System (MCAS), a new automatic flight control feature. Investigations in both crashes determined that Boeing and the FAA favored cost-saving solutions, but ultimately produced a flawed design of the MCAS instead.[1] The FAA's Organization Designation Authorization program, allowing manufacturers to act on its behalf, was also questioned for weakening its oversight of Boeing.
