FAA Targets Airbus Fire Switch Glitches in New Rule
Published Date: 9/3/2026
Proposed Rule
Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A318, A319, A320, and A321 series airplanes. This proposed AD was prompted by reports of one engine fire switch self-releasing, causing an uncommanded in-flight shut down to one engine. This proposed AD would require, for certain airplanes, replacement of certain fire panels, and for certain other airplanes, a general visual inspection of certain fire panels, and applicable on- condition actions. This proposed AD would also limit the installation of affected parts under certain conditions.
Analyzed Economic Effects
2 provisions identified: 0 benefits, 2 costs, 0 mixed.
Mandatory Fire-Panel Inspections and Replacements
The FAA proposes a new airworthiness directive that would require certain Airbus A318, A319, A320, and A321 airplanes to have specified fire panels replaced, and other airplanes to receive a general visual inspection of those fire panels with on‑condition actions. The rule would incorporate EASA AD 2025-0274R1 (dated July 7, 2026) by reference and would also limit installation of affected parts under certain conditions to address reports of engine fire switches self-releasing and causing uncommanded in‑flight engine shutdowns.
Estimated Compliance Costs and Paperwork Burden
The FAA estimates the proposed AD would affect 1,996 U.S.-registered airplanes. Estimated per-aircraft costs include $13,352 for replacement (for 125 airplanes), up to $595 for inspection (for 1,871 airplanes), and $85 for reporting (1 hour) per response; total estimated costs shown are $1,669,290 for replacements, up to $1,113,245 for inspections, and $159,035 for reporting. The Paperwork Reduction Act burden for reporting uses OMB Control Number 2120-0056 and is estimated at about 1 hour per response.

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.
2026-18052, Airworthiness Directives; Airbus SAS Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A318-112; Model A319-115, -132, and -133; Model A320-214, -216, -232, -233, -251N, and -271N; and Model A321-211, -213, -231, -271N, -251NX, -253NX, and -271NX airplanes. This AD was prompted by a quality escape identified in the production assembly line on the main landing gear (MLG) support rib 5 lugs, which resulted in tool mark damage in the bore of the forward and aft lugs. This AD requires repetitive detailed visual inspections (DVIs) of the affected parts and applicable corrective actions. This AD also provides a one- time special detailed inspection (SDI) as a terminating action for the repetitive inspections. The FAA is issuing this AD to address the unsafe condition on these products.
2026-18025, Agency Information Collection Activities: Requests for Comments; Clearance for Renewal of Information Collection: Privacy International Civil Aviation Organization (ICAO) Address Correction
In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval for an information collection renewal. The collection involves an aircraft operator's request for a privacy ICAO address through a web-based application process. The information to be collected is necessary to qualify for the authorized use of the privacy ICAO address services and for monitoring to support continued airworthiness and enforcement activities.

NMFS proposes regulations to modify the Pacific halibut (halibut) Individual Fishing Quota (IFQ) Program to revise vessel harvest limitations for IFQ halibut harvested in IFQ regulatory Areas (Areas) 4A, 4B, 4C, 4D, and 4E by establishing a vessel harvest limit of five percent of the total annual commercial catch limit across Areas 4A, 4B, 4C, 4D, and 4E. This action would also exclude IFQ halibut harvest derived from quota held by a Community Quota Entity (CQE) in Area 4B from accruing under the proposed five percent vessel harvest limit across Areas 4A, 4B, 4C, 4D, and 4E. This action would provide additional flexibility for halibut IFQ Program fishery participants in Areas 4A, 4B, 4C, 4D, and 4E, where fishery conditions continue to be challenging. This action would promote the goals and objectives of the IFQ Program, the Northern Pacific Halibut Act of 1982 (Halibut Act), and other applicable laws.
