In the United States Senate, on June 17, 2020, the “Aircraft Safety and Reform Act” was introduced to effectively reverse provisions of the 2018 FAA Re-authorization that allowed Boeing leeway to decide that the B-737 MAX 800 and 900 are safe to fly.
Boeing and other component manufacturers had been delegated safety certification responsibilities that would now require detailed and continuous “surveillance and audit” by FAA.
The bipartisan move to regulate the design and manufacture of aircraft, engines control technologies etc. curiously started in the Senate. FAA Re-Authorization includes policy and appropriations; routinely undertaken by the House Transportation and Infrastructure Committee.
