Boeing paid the Federal Aviation Administration (FAA) $17 million to resolve allegations of installing nonconforming parts in the wings of 737 Max and NG aircraft. The FAA found that Boeing installed equipment on 759 Boeing 737 Max and NG aircraft containing sensors that were not approved for that equipment; submitted approximately 178 Boeing 737 Max aircraft for airworthiness certification when the aircraft potentially had nonconforming slat tracks installed; and improperly marked those slat tracks. The settlement amount stemmed from three civil penalty letters issued in 2019 and 2020 that assessed a total of $29 million in fines—the FAA mitigated $1.8 million in recognition of Boeing’s corrective actions and deferred an additional $10.2 million.
