Airworthiness Directives; Airbus SAS Airplanes
Published Date: 7/29/2026
Rule
Summary
The FAA is superseding Airworthiness Directive (AD) 2025-16- 12, which applied to all Airbus SAS Model A319-151N, -153N, -171N, and -173N airplanes; Model A320-251N, -252N, -253N, -271N, -272N, and -273N airplanes; and Model A321-251N, -252N, -253N, -271N, -272N, -251NX, - 252NX, -253NX, -271NX, -272NX, -253NY, and -271NY airplanes. AD 2025- 16-12 required revising the existing airplane flight manual (AFM) and the existing FAA-approved minimum equipment list (MEL), allowed replacement of each affected high-pressure bleed valve (HPV) as an optional terminating action, and prohibited the installation of affected parts. Since the FAA issued AD 2025-16-12, the FAA has determined that repetitive replacement of the HPV clips is necessary to address the unsafe condition. This AD continues to require the actions in AD 2025-16-12 and requires repetitive replacement of each affected HPV clip. The FAA is issuing this AD to address the unsafe condition on these products.
Analyzed Economic Effects
1 provisions identified: 0 benefits, 1 costs, 0 mixed.
Airbus HPV Clip Replacement Mandate
If you operate the Airbus A319, A320, or A321 NEO variants listed in this AD, you must revise the airplane flight manual (AFM) and your FAA‑approved minimum equipment list (MEL), stop installing the affected parts, and perform repetitive replacement of each affected high‑pressure bleed valve (HPV) retention clip. The AD is effective September 2, 2026, applies to 554 U.S.-registered airplanes, and the FAA estimates per-airplane costs as follows: retained actions $170 per airplane, the new repetitive replacement actions $808 per airplane, and an optional terminating action $5,520 per airplane.

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.
2026-15283, Airworthiness Directives; Airbus Helicopters
The FAA proposes to supersede Airworthiness Directive (AD) 2022-01-01, which applies to all Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350D, AS355E, AS355F, AS355F1, AS355F2, AS355N, AS355NP, AS 365 N2, AS 365 N3, EC130B4, EC130T2, SA 365 C1, SA 365 C2, SA 365 N, and SA 365 N1 helicopters. AD 2022-01-01 requires the application of alignment markings on, and repetitive inspections of, the main rotor (MR) pitch rod upper links and, depending on findings, the accomplishment of applicable corrective actions. Since the FAA issued AD 2022-01-01, the manufacturer designed a new pitch rod lever axis attachment screw and issued applicable modification material as an alternative option. This proposed AD would retain all the actions of AD 2022-01-01 and would allow the modification as a terminating action to the repetitive inspections and corrective actions. This proposed AD would also prohibit installing a certain affected pitch rod lever axis attachment screws unless certain requirements are met. The FAA is proposing this AD to address the unsafe condition on these products.
2026-15239, Airworthiness Directives; The Boeing Company Airplanes
The FAA is superseding Airworthiness Directive (AD) 2024-19- 14, which applied to certain The Boeing Company Model 777-200, 777- 200LR, 777-300ER, and 777F series airplanes. AD 2024-19-14 required repetitive inspections and bond resistance measurement of the bonding jumpers on the first fuel feed tube installed immediately forward of the wing front spar at the left and right main fuel tank penetrations and applicable corrective actions. This AD was prompted by a determination that additional inspections are required to address the unsafe condition. This AD requires repetitive detailed inspections (DETs), repetitive bond resistance measurement, and applicable on- condition actions. This AD also expands the applicability and requires revising the existing maintenance or inspection program, as applicable, to incorporate a certain airworthiness limitation. The FAA is issuing this AD to address the unsafe condition on these products.
2026-15072, Airworthiness Directives; The Boeing Company Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-8, 737-9, and 737-8200 airplanes. This proposed AD was prompted by a report that certain passenger seat assemblies were not correctly installed in the seat tracks. This proposed AD would require a detailed inspection of the seat track fittings of each left and right side track-mounted passenger seat assembly for correct installation and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.

The Food and Drug Administration (FDA) is classifying the phase-changing fiducial marker for radiation therapy into class II (special controls). The special controls that apply to the device type are identified in this order and will be part of the codified language for classification of the phase-changing fiducial marker for radiation therapy. We are taking this action because we have determined that classifying the device into class II will provide a reasonable assurance of safety and effectiveness of the device. We believe this action will also enhance patients' access to beneficial innovative devices, in part by reducing regulatory burdens.
