Airworthiness Directives; Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
Published Date: 7/27/2026
Proposed Rule
Summary
The FAA proposes to supersede Airworthiness Directive (AD) 2024-22-01, which applies to certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2024-22-01 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2024-22-01, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would continue to require certain actions in AD 2024-22-01 and would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.
Analyzed Economic Effects
3 provisions identified: 1 benefits, 2 costs, 0 mixed.
Must revise maintenance programs
If you operate Airbus Canada Model BD-500-1A10 or BD-500-1A11 airplanes that have not already incorporated Issue No. 019.01, you must revise your existing maintenance or inspection program to include the new or more restrictive airworthiness limitations specified in Transport Canada AD CF-2025-67. The AD requires you to incorporate Airbus Canada A220 Airworthiness Limitations, BD500-3AB48-11400-02, Issue No. 019.01, dated August 28, 2025, with the compliance time to revise the maintenance or inspection program within 30 days after the effective date of this AD.
FAA estimates compliance labor costs
The FAA estimates this AD would affect 184 U.S.-registered airplanes. The agency estimates the cost per operator to revise and implement the maintenance/inspection program is 90 work-hours at $85 per hour, equal to $7,650 for the retained actions from AD 2024-22-01, and it estimates an average of 90 work-hours (also $7,650) per operator for the new proposed actions.
Incorporating Issue 019.01 ends CCMR requirement
After you incorporate Airbus Canada A220 Airworthiness Limitations Issue No. 019.01 (dated August 28, 2025) into your maintenance or inspection program, the AD terminates the prior requirement to incorporate Candidate Certification Maintenance Requirements (CCMRs). The AD states the initial compliance times for tasks in Issue No. 019.01 are at the applicable thresholds or within 30 days after the effective date of this AD, whichever occurs later.

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.
2026-15072, 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.
2026-15062, Amendment of Class D Airspace and Class E Airspace Over Westfield, MA
The FAA is updating the airspace rules over Westfield, MA to fix the airport name, coordinates, and some legal wording. These changes make the airspace descriptions clearer and follow current FAA guidelines. Pilots and local air traffic controllers will see these updates starting October 29, 2026, with no extra costs involved.
2026-15004, Airworthiness Directives; Stemme GmbH Gliders
If you own a Stemme TSA-M Model S6-RT or S 12 glider, listen up! The FAA found some fuel pumps that might leak and wants you to check yours ASAP. If your pump has the wrong parts, you’ll need to swap them out with approved ones by July 24, 2026, to keep flying safe and sound—no surprise costs mentioned, just peace of mind.

Next: 2026-15080, Reducing Barriers to Medical Use Licensing
The U.S. Nuclear Regulatory Commission (NRC) is proposing to amend its regulations to reduce barriers to medical use licensing. This proposed rule responds to Executive Order 14300, "Ordering the Reform of the Nuclear Regulatory Commission," which requires the NRC to conduct a review and wholesale revision of its regulations. This proposed rule, if adopted, would reduce overly prescriptive regulations, increase flexibility, and modernize radiation safety practices for the medical use of byproduct material. It also would enable more efficient and predictable licensing for emerging medical technologies and reduce unnecessary burden in training and experience requirements for medical authorized users. The NRC is revising guidance for this proposed rule. This proposed rule also would incorporate minor editorial corrections.
