Airworthiness Directives; Airbus SAS Airplanes
Published Date: 7/30/2026
Rule
Summary
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-841 and Model A330-941 airplanes. This AD was prompted by reports of crack findings on the sloping rib. This AD requires a repetitive inspection of the external surface of each sloping rib and each slat 1 inboard seal, and applicable corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
Analyzed Economic Effects
2 provisions identified: 0 benefits, 2 costs, 0 mixed.
A330-841/941: Required repetitive inspections
If you operate Airbus Model A330-841 or A330-941 airplanes, you must perform repetitive inspections of the external surface of each sloping rib and each slat 1 inboard seal and do any required corrective actions. This AD adopts the actions in EASA AD 2025-0179 and is effective September 3, 2026.
Estimated compliance cost and affected fleet
The FAA estimates this AD affects 37 U.S.-registered A330-841 and A330-941 airplanes. The FAA estimates 1 work-hour per inspection at $85 per airplane (cost per product $85) and a total estimated cost to U.S. operators of $3,145; on-condition repair costs were not estimated.

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.
2026-15370, Airworthiness Directives; Leonardo S.p.a. Helicopters
The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.a. Model AW189 helicopters. This AD was prompted by reports of cracking on the ejector ducts. This AD requires repetitively inspecting the left-hand (LH) side and right-hand (RH) side ejector ducts, including the exhaust bracket reinforcements and reinforcement plates, and, depending on the results, replacing any affected ejector duct. The FAA is issuing this AD to address the unsafe condition on these products.
2026-15455, Airworthiness Directives; Airbus SAS Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A330-200 and A330-300 series airplanes modified by a certain supplemental type certificate (STC). This AD was prompted by a finding that, for airplanes with a flightcrew oxygen system supplied by a single oxygen cylinder, the oxygen supply would not be sufficient under all circumstances for extended operations (ETOPS) with a maximum diversion time of 180 minutes (ETOPS-180) with four flightcrew members. This AD requires revising the existing Airplane Flight Manual Supplement (AFM-S) to limit ETOPS-180 operations to three flightcrew members, as applicable, and correct minimum oxygen dispatch pressure information. The FAA is issuing this AD to address the unsafe condition on these products.
2026-15412, Airworthiness Directives; MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
The FAA is adopting a new airworthiness directive (AD) for all MHI RJ Aviation ULC Model CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2C11 (Regional Jet Series 550), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900) airplanes. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD 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 adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by an in-service event where a main landing gear tire burst upon landing. This AD requires an inspection to determine if an affected brake control unit (BCU) is installed and replacement of affected BCUs. This AD also prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.
Next: 2026-15411, Airworthiness Directives; Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
The FAA is superseding Airworthiness Directive (AD) 2025-06- 01, which applied to all Airbus Canada Limited Partnership Model BD- 500-1A10 and BD-500-1A11 airplanes. AD 2025-06-01 required revising the existing airplane flight manual (AFM) to incorporate the procedures for the flightcrew to manually isolate the opposite functional engine in the event of an engine bleed duct large leak condition. Since the FAA issued AD 2025-06-01, an electronic engine control (EEC) software update has been developed to address the unsafe condition. This AD continues to require the actions in AD 2025-06-01 and requires installing a certain EEC software update on both engines. This AD also removes airplanes from the applicability. The FAA is issuing this AD to address the unsafe condition on these products.
