FAA Orders Fuel Line Checks on More Airbus Planes
Published Date: 9/2/2026
Proposed Rule
Summary
The FAA wants to update safety rules for certain Airbus Canada airplanes by checking and fixing fuel line parts that might be damaged. They’re adding four more planes to the list that need these checks to keep flying safe. If you own or operate these planes, you’ll want to act before October 19, 2026, to avoid any costly surprises.
Analyzed Economic Effects
3 provisions identified: 1 benefits, 2 costs, 0 mixed.
Inspections and Repairs Required for Fuel Lines
If you own or operate certain Airbus Canada Model BD-500-1A10 or BD-500-1A11 airplanes, you must inspect the left and right motive flow (MF) flexible fuel line assemblies (including flexible hose and shroud assemblies) and replace any damaged assembly in accordance with Transport Canada AD CF-2025-47. The FAA is proposing to supersede AD 2021-17-07, expand applicability to four additional airplanes, and retain the inspection and replacement requirements; comments are due by October 19, 2026.
Estimated Compliance and Repair Costs
The FAA estimates this AD would affect 13 U.S.-registered airplanes. The estimated labor cost for the retained and new required actions is $850 per airplane; total estimated cost to U.S. operators for the 9 retained airplanes is $7,650 and for the 4 newly added airplanes is $3,400. If on-condition repairs are needed, the FAA estimates parts at $9,920 plus 1 work-hour ($85) for a cost of $10,005 per pylon.
Removed Requirement to Return Removed Parts
The Transport Canada material referenced instructs sending removed parts to the manufacturer, but this FAA proposed AD explicitly does not require returning removed parts to the manufacturer. That means you do not have to ship removed parts back as part of complying with this FAA AD.

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.
2025-04846, Extension of the Prohibition Against Certain Flights in the Territory and Airspace of Libya
The FAA is extending the ban on certain flights over Libya for three more years, until March 20, 2028. This affects U.S. airlines, commercial operators, and pilots with FAA certificates flying in Libyan airspace, due to ongoing safety risks. The rule also reminds everyone how to apply for special approvals or exemptions if needed.
2025-03853, Enforcement Policy Regarding “Drug and Alcohol Testing of Certificated Repair Station Employees Located Outside of the United States; Correction”
The FAA is giving repair stations outside the U.S. a break by delaying enforcement of new drug and alcohol testing rules until March 20, 2025. This means affected repair stations don’t have to worry about penalties if they aren’t fully following the updated rules just yet. The delay helps everyone get ready without rushing or extra costs.

FAA proposes to implement certain Special Air Traffic Rules in the airspace in the vicinity of the President Donald J. Trump International Airport (DJT), formerly Palm Beach International Airport (PBI). U.S. Secret Service (USSS) requested FAA restrict aircraft operations in the vicinity of President Trump's Florida non- Governmental property. To provide adequate safeguards for USSS to secure the non-Governmental property and safeguard USSS protectees in the interest of national security, FAA is proposing to implement Special Air Traffic Rules restricting aircraft from operating in the President Donald J. Trump International Airport Special Flight Rules Area unless certain conditions are met.
Next: 2026-18015, Television Broadcasting Services Colusa, California
This document proposes to amend the Table of TV Allotments (Table) of the Federal Communications Commission's (Commission) rules in response to a petition for rulemaking filed by One Ministries, Inc. (Petitioner), the licensee of NCE television station KEDS(TV) (KEDS or Station), Colusa, California (Colusa). The Petitioner requests the substitution of UHF channel 14 in place of its current VHF channel 2 at Colusa in the Table with the technical parameters specified in the Petition. In support of its channel substitution request, the Petitioner asserts that allowing the Station to move to a UHF channel would serve the public interest by improving signal reception for viewers. The Petitioner observes that the Commission has recognized that VHF channels have certain characteristics that have posed challenges for their use in providing digital television service, including propagation characteristics allowing undesired signals and noise to be receivable at relatively farther distances. Additionally, the Petitioner notes that the Commission has observed large variability in the performance of indoor antennas available to consumers, with most antennas receiving fairly well at UHF and the substantial majority not so well to very poor at high-VHF. An engineering statement provided by the Petitioner confirms that the proposed channel *14 contour would provide full principal community coverage to Colusa.
