Falcon Jets Need Software Fix for Silent Wing Issue

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.

2026-18520, Airworthiness Directives; Dassault Aviation Airplanes

The FAA proposes to adopt a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 7X, MYSTERE-FALCON 900, FALCON 900EX, FALCON 2000, and FALCON 2000EX airplanes. This proposed AD was prompted by reported occurrences of seats sliding without passenger input. The cabin seat track locking mechanism was found to jam in isolated conditions during taxi, take-off, and landing (TTOL). This proposed AD would require modifying or replacing each affected seat. This proposed AD would also prohibit the installation of affected seats. The FAA is proposing this AD to address the unsafe condition on these products.

2026-18423, Airworthiness Directives; International Aero Engines AG Engines; Correction

The FAA is correcting an airworthiness directive (AD) that was published in the Federal Register. That AD applies to certain International Aero Engines AG (IAE AG) Model V2522-A5, V2524-A5, V2525- D5, V2527-A5, V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, V2531-E5, and V2533-A5 engines. As published, paragraph (g) of the regulatory text contains a typographical error. This document corrects that error. In all other respects, the original document remains the same.

Previous: 2026-11215, Airworthiness Directives; Airbus SAS Airplanes

The FAA is requiring fixes on certain Airbus A350-941 airplanes because some fasteners didn’t get the right protective coating during production, which could cause safety issues. Airlines must replace affected parts and add extra protection by July 9, 2026. This update helps keep flights safe without causing big delays or costs.

Next: 2026-11217, Airworthiness Directives; De Havilland Aircraft of Canada Limited (Type Certificate Previously Held by Bombardier, Inc.) Airplanes

The FAA is requiring all De Havilland DHC-8 airplanes to get regular checks for cracked and rusty barrel nuts near the wings and tail. These inspections start July 9, 2026, to keep flights safe and avoid bigger repairs later. Airlines will need to spend some time and money on these checks, but it’s all about keeping the planes flying strong and safe.
