Content: In December 2018, the FAA privately predicted that MCAS could cause 15 crashes over 30 years. On April 4th, the Ethiopian preliminary report confirmed that MCAS was active, and the crew had complied with the procedure. FAA certification of the MAX was subsequently investigated by the U.S. Congress and multiple U.S. government agencies, including the Transportation Department, FBI, NTSB, Inspector General and special panels. Engineering reviews uncovered other design problems, unrelated to MCAS, in the flight computers and cockpit displays. The Indonesian NTSC and the Ethiopian ECAA both attributed the crashes to faulty aircraft design and other factors, including maintenance and flight crew actions. Lawmakers investigated Boeing's incentives to minimize training for the new aircraft. The FAA revoked Boeing's authority to issue airworthiness certificates for individual MAX airplanes and imposed a fine on Boeing for exerting "undue pressure" on its designated aircraft inspectors. In August 2020, the FAA published requirements for fixing the aircraft and improving pilot training. On November 18, 2020, the FAA cleared the MAX to return to service, followed by European and Canadian regulators in January 2021. The grounding cost Boeing an estimated US$20 billion in fines, compensation and legal fees, and indirect losses in the form of 1,200 cancelled orders valued at more than US$60 billion.
