Groundings Five Shenzhen Airlines 737 MAX 8s (foreground, red livery) grounded at the Shenzhen Bao'an International Airport, March 2019
in December 2020, and was recertified in Europe and Canada by January 2021. The MAX resumed commercial flights in the U.S. The accidents and grounding cost Boeing an estimated $20 billion in fines, compensation and legal fees, with indirect losses of more than $60 billion from 1,200 cancelled orders. On November 18, 2020, the FAA ended the 20-month grounding, the longest ever of a U.S. In August 2020, the FAA published requirements for fixing each aircraft and improving pilot training. The FAA revoked Boeing's authority to issue airworthiness certificates for individual MAX airplanes and fined Boeing for exerting "undue pressure" on its designated aircraft inspectors. Lawmakers investigated Boeing's incentives to minimize training for the new aircraft. The Indonesian NTSC and the Ethiopian ECAA both attributed the crashes to faulty aircraft design and other factors, including maintenance and flight crew actions.
Engineering reviews uncovered other design problems, unrelated to MCAS, in the flight computers and cockpit displays. government agencies, including the Transportation Department, FBI, NTSB, Inspector General and special panels. įAA certification of the MAX was subsequently investigated by the U.S. In April 2019, the Ethiopian preliminary report stated that the crew had attempted the recovery procedure, and Boeing confirmed that MCAS had activated in both accidents. In December 2018, the FAA privately predicted that MCAS could cause 15 crashes over 30 years. Boeing avoided revealing MCAS until pilots requested further explanation.

In November 2018, after the Lion Air accident, Boeing instructed pilots to take corrective action in case of a malfunction, when the airplane would enter a series of automated nosedives. In 2016, FAA approved Boeing's request to remove references to a new Maneuvering Characteristics Augmentation System (MCAS) from the flight manual. By then, 51 other regulators had already grounded the plane, and by March 18, 2019, all 387 of the aircraft in service were grounded. Federal Aviation Administration (FAA) resisted grounding the aircraft until March 13, 2019, when it received evidence of accident similarities. 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 Octoand Ethiopian Airlines Flight 302 on March 10, 2019. of grounding by the FAA: 1 year, 8 months and 5 days (619 days)Īirworthiness revoked after recurring flight control failure.between accidents: 4 months and 10 days.First grounding order: March 11, 2019 ( ) by the Civil Aviation Administration of China (CAAC) – January 13, 2023 ( ).First grounding: March 10, 2019 ( ) by Ethiopian Airlines (superseded).Ethiopian Airlines accident: March 10, 2019.A parking lot at Boeing Field in Seattle, Washington, filled with undelivered Boeing 737 MAX aircraft during the grounding
