FAA OKs breaking sound barrier: supersonic petition granted.
Published Date: 9/11/2026
Notice
Summary
This notice summarizes the petition Hermeus Corporation submitted to FAA requesting a special flight authorization as provided for in FAA regulations. The notice also provides for public awareness of FAA's decision to grant Hermeus Corporation's request. FAA is not requesting comments on the petition or FAA's decision regarding the petition because a special flight authorization petition to exceed Mach 1 follows a separate regulatory process.

2026-15585, Requirements for Interference-Tolerant Radio Altimeter Systems
In July 2025, President Trump signed the One Big Beautiful Bill Act. Section 40002 of that law re-institutes the Federal Communications Commission's general auction authority and specifically directs the Commission to complete a system of competitive bidding for not less than 100 megahertz in the 3.98-4.2 gigahertz band (Upper C- band). This final rule supports the Federal Communications Commission's July 2026 Report and Order that makes 160 megahertz of the Upper C-band available for terrestrial wireless flexible use via a system of competitive bidding. To ensure safe, efficient, and reliable aviation operations in the presence of wireless signals in the C-band, the Federal Aviation Administration is issuing new regulations that require all radio altimeters to meet specific minimum performance requirements. These new radio altimeters must withstand interference from wireless signals in neighboring spectrum bands and continue to provide accurate altitude readings to both pilots and integrated aircraft safety systems. These regulations require all aircraft equipped with radio altimeters operating under part 121 and those aircraft with radio altimeters operating under part 129 with 30 or more passenger seats or a payload capacity of more than 7,500 pounds to comply with the minimum performance requirements by December 30, 2030, which is prior to the date the Federal Communications Commission authorizes the use of the Upper C-band for new wireless services, as stated in its Report and Order. All other aircraft equipped with radio altimeters that are required to comply with part 91, including aircraft operating under parts 125, 133, 135, 136, 137, 194, and all other aircraft operating under part 129 that are not subject to the initial deadline, must comply with the same minimum performance requirements on or before October 31, 2034.
2026-13440, Enabling Supersonic Overland Flight
The FAA wants to let supersonic planes fly over land again by updating old rules that banned them because of loud sonic booms. Thanks to new tech that keeps booms quiet, this change will open the door for faster, cooler flights across the U.S., helping America lead the world in supersonic travel. People and companies interested in supersonic flight should share their thoughts by August 17, 2026.
2026-13126, Designation-Restrict the Operation of Unmanned Aircraft in Close Proximity to a Fixed Site Facility; Extension of Comment Period
The FAA is giving more time—until August 5, 2026—for people to share their thoughts on new rules that would limit drone flights near important fixed sites like power plants or airports. This affects drone operators and facility owners who want to keep the skies safe and secure. No new costs yet, just extra time to weigh in and help shape the rules.
2026-08943, Designation-Restrict the Operation of Unmanned Aircraft in Close Proximity to a Fixed Site Facility
The FAA is proposing new rules to keep drones away from certain important fixed sites like power plants or airports to keep everyone safe and secure. If you own or operate one of these sites, you can request a drone flight restriction zone to protect your property and people nearby. Comments are open until July 6, 2026, and these changes could affect drone pilots and site operators, but no big costs are expected.
2026-18601, Airworthiness Directives; Dassault Aviation Airplanes
The FAA is superseding Airworthiness Directive (AD) 2023-23- 06, which applied to certain Dassault Aviation Model FALCON 2000EX airplanes. AD 2023-23-06 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2023-23- 06, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This AD continues to require certain actions in AD 2023-23-06 and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.
2026-18602, Airworthiness Directives; Dassault Aviation Airplanes
The FAA is superseding Airworthiness Directive (AD) 2023-22- 12, which applied to all Dassault Aviation Model FALCON 2000 airplanes. AD 2023-22-12 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2023-22-12, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This AD continues to require certain actions in AD 2023- 22-12 and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.

Significant and immediate investment in linear utility infrastructure is essential to meet the surging energy needs of critical manufacturing and emerging technologies that drive America's security, prosperity, and global leadership. Highway and rail transportation assets represent significant linear rights-of-way (ROWs) that have traditionally been reserved solely for transportation needs. The U.S. Department of Transportation (DOT or the Department), through the Build America Bureau, created the America's Great Corridors of Commerce (AGCC) initiative to unleash opportunities for both highway and rail ROW owners to generate revenue streams through utility colocation that can fund transportation improvement projects, while simultaneously delivering significant economic development to these areas. AGCC is a voluntary, applicant-driven process in which ROW owners propose corridors for strategic colocation of utility infrastructure in the transportation ROW through an innovative public- private partnership (P3) model. Selected corridors receive concierge technical assistance and enhanced collaboration from a team of experts from relevant Federal agencies. In this RFI, DOT seeks comments from the public and interested parties on the AGCC model and the proposed elements of DOT's anticipated AGCC designation process.
