FAA Orders Airbus A350 Fastener Tightening Fix
Published Date: 6/9/2026
Rule
Summary
The FAA is requiring certain Airbus A350-941 airplanes to fix a problem where some fasteners weren’t tightened properly, which could be unsafe. Airlines must replace affected parts and add extra protection by July 14, 2026. This keeps flights safe but might cost some time and money for the fixes.
Analyzed Economic Effects
2 provisions identified: 1 benefits, 1 costs, 0 mixed.
Airlines must fix A350 fasteners
If you operate certain Airbus A350-941 airplanes, the FAA requires you to replace affected fasteners and apply additional head nut cap protection per EASA AD 2025-0209. This work must be done in accordance with the AD and is effective July 14, 2026. The rule responds to improperly torqued fasteners that could compromise structural integrity and, in case of a fuel leak, could create an ignition source and possibly an uncontrolled fire.
Estimated repair hours and costs
The FAA estimates this AD affects 2 airplanes of U.S. registry. Estimated labor is up to 68 work hours at $85 per hour, parts cost is up to $6,720, and the FAA lists cost per product up to $13,440.

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.

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.
