FAA Fixes Breathing Rules for Safran Aircraft Oxygen Gear
Published Date: 12/30/2025
Rule
Summary
The FAA is updating safety rules for certain Aerospace & Defense Oxygen Systems SaS breathing gear used on aircraft. This new rule, effective January 14, 2026, changes how crews should put on the equipment to keep everyone safer. If you operate or maintain these systems, you’ll need to follow the new steps soon, but there’s no big cost impact expected.
Analyzed Economic Effects
4 provisions identified: 3 benefits, 1 costs, 0 mixed.
Must update PBE donning procedures
If your aircraft has Aerospace & Defense Oxygen Systems SaS portable breathing equipment (P/N 15-40F-11 or P/N 15-40F-80), you must update the instructions for how crews put on the PBE within 30 days after the rule is effective. The AD is effective January 14, 2026, so the updates must be done within 30 days of that date and must follow paragraph 3.C., “Procedure,” of Safran Aerosystems Service Bulletin 1540F-35-001 dated October 10, 2025.
Two optional ways to comply
Operators may comply by either amending applicable aircraft operation manual(s) to include the updated donning instructions or by disseminating the updated instructions to all flight and cabin crewmembers. Both methods are listed as acceptable ways to meet the AD requirement in paragraph (h) of the rule.
Pilots may record compliance for small aircraft
For aircraft certificated in any category except transport category airplanes, an owner/operator (pilot) who holds at least a private pilot certificate may perform the update and must record compliance in the aircraft maintenance records per 14 CFR 43.9(a) and 91.417(a)(2)(v). This is an allowance in paragraph (g)(2) of the AD.
Estimated compliance time and cost
The FAA estimates this AD affects about 80,000 appliances (PBE units) and that the required action takes about 1 work-hour at $85 per appliance (parts $0). The FAA estimates total cost on U.S. operators up to $6,800,000, noting it is unknown how many of the 80,000 appliances are on U.S.-registered aircraft.

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.
2026-17551, Airworthiness Directives; Airbus SAS Airplanes
The FAA is superseding Airworthiness Directive (AD) 2024-25- 06, which applied to all Airbus SAS Model A318 and A320 series airplanes; and Model A319-111, -112, -113, -114, -115, -131, -132, - 133, -151N, -153N, and -171N airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -252N, -253N, -271N, -272N, - 251NX, -252NX, -253NX, -271NX, -272NX, and -253NY airplanes. AD 2024- 25-06 required repetitive inspections of the main landing gear (MLG) door actuators and, depending on findings, accomplishment of applicable corrective actions, and prohibited the installation of affected parts. Since the FAA issued AD 2024-05-06, the FAA determined that replacing the MLG door actuators is necessary to address the unsafe condition, and the applicability and definition of an affected part must be expanded. This AD continues to require the actions in AD 2024-25-06, requires replacing affected parts with serviceable parts, and expands the applicability and definition of an affected part. The FAA is issuing this AD to address the unsafe condition on these products.
2026-17552, Airworthiness Directives; Airbus SAS Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A320-211, -212, -214, -216, -231, -232, and - 233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. This AD was prompted by a fatigue test that identified cracks in the forward and aft upper corner of the bulk cargo door. This AD requires a rototest inspection for cracks and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
