Executive order

By the authority vested in me as President by the Constitution and the laws of the United States of America, it is hereby ordered:

Section 1. Purpose. The United States stands at the threshold of a bold new chapter in aerospace innovation. For more than 50 years, outdated and overly restrictive regulations have grounded the promise of supersonic flight over land, stifling American ingenuity, weakening our global competitiveness, and ceding leadership to foreign adversaries. Advances in aerospace engineering, materials science, and noise reduction now make supersonic flight not just possible, but safe, sustainable, and commercially viable. This order begins a historic national effort to reestablish the United States as the undisputed leader in high-speed aviation. By updating obsolete standards and embracing the technologies of today and tomorrow, we will empower our engineers, entrepreneurs, and visionaries to deliver the next generation of air travel, which will be faster, quieter, safer, and more efficient than ever before.

Sec. 2. Regulatory Reform for Supersonic Flight. (a) The Administrator of the Federal Aviation Administration (FAA) shall take the necessary steps, including through rulemaking, to repeal the prohibition on overland supersonic flight in 14 CFR 91.817 within 180 days of the date of this order and establish an interim noise-based certification standard, making any modifications to 14 CFR 91.818 as necessary, as consistent with applicable law. The Administrator of the FAA shall also take immediate steps to repeal 14 CFR 91.819 and 91.821, which will remove additional regulatory barriers that hinder the advancement of supersonic aviation technology in the United States.

(b) Within 18 months of the date of this order, the Administrator of the FAA shall issue a Notice of Proposed Rulemaking (NPRM) to establish a standard for supersonic aircraft noise certification under 14 CFR Part 36 and amend 14 CFR 91.817. The proposed rule shall define acceptable noise thresholds for takeoff, landing, and en-route supersonic operation based on operational testing and research, development, testing, and evaluation (RDT&E) data as identified in subsection 3(a) of this order, and considering community acceptability, economic reasonableness, and technological feasibility. The proposed rule shall further specify a process for periodic review and update of the rule to reflect future advances in aircraft noise reduction technology. Any final rule in connection with the NPRM shall be issued within 24 months of the date of this order.

Sec. 3. Advancing Supersonic Research and Development. (a) The Director of the Office of Science and Technology Policy (OSTP) shall, in consultation with the heads of relevant executive departments and agencies (agencies), including the Secretary of Defense, the Secretary of Commerce, the Secretary of Transportation, and the Administrator of the National Aeronautics and Space Administration, coordinate supersonic research and development through the National Science and Technology Council, with the goal of:
