Friday's FAA decision lets Boeing again issue airworthiness certificates for all 737 Max jets and 787 Dreamliners before delivery, fully restoring a power the agency had taken over.
Eight months of alternating certification work showed comparable production-quality findings whether Boeing or the FAA signed off, leading the regulator to say it could safely return the responsibility.
The FAA had only partially eased the restriction in September, allowing Boeing to certify some Max and Dreamliner deliveries on alternating weeks while the agency handled the rest.
The move marks a regulatory vote of confidence after years of safety turmoil tied to the 2018 and 2019 fatal 737 Max crashes and the January 2024 737 Max 9 door-plug blowout.
