Airbus Planes Told to Move a Harness
Published Date: 6/29/2026
Proposed Rule
Summary
The FAA wants to fix a safety issue on certain Airbus Canada airplanes where a hydraulic pump harness is too close to the plane’s structure, which could cause problems. They’re proposing a simple fix to move the harness and keep flights safe. Owners need to comment by August 13, 2026, and the fix might cost some time and money but keeps everyone flying worry-free.
Analyzed Economic Effects
2 provisions identified: 1 benefits, 1 costs, 0 mixed.
Required harness modification for safety
If you operate Airbus Canada Model BD-500-1A10 or BD-500-1A11 airplanes, the FAA proposes a rule requiring you to modify the hydraulic motor pump harness installation by adding a clamp support on the bracket between fuselage frames FR 80 and FR 81 as specified in Transport Canada AD CF-2025-18 (dated March 21, 2025). The change is meant to stop harness chafing that could create an ignition source and lead to an uncontained fire.
Compliance cost per airplane estimated
The FAA estimates the modification will take 1 work-hour at $85 plus $27 in parts, for a total cost of $112 per airplane. The FAA estimates this proposed AD would affect 101 U.S.-registered airplanes, for a total estimated cost to U.S. operators of $11,312.

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.
2026-16672, Airworthiness Directives; Air Tractor, Inc. Airplanes
The FAA is superseding Airworthiness Directive (AD) 2024-16- 06, which applied to all Air Tractor, Inc. (Air Tractor) Model AT-802 and AT-802A airplanes with Wipaire, Inc. Supplemental Type Certificate (STC) No. SA01795CH installed. AD 2024-16-06 required repetitively inspecting the left and right, forward and rear, horizontal stabilizer spars for cracks, replacing any horizontal stabilizer spar found cracked or damaged, installing bathtub fittings, and reporting inspection results to the FAA. Since the FAA issued AD 2024-16-06, additional cracks in the horizontal stabilizer spars were reported where the vertical fin structural support brace mounts to the horizontal stabilizer spar. This AD retains all the actions of AD 2024- 16-06 and adds inspections to another area. The FAA is issuing this AD to address the unsafe condition on these products.
2026-16655, Airworthiness Directives; Pratt & Whitney Canada Corp. Engines
The FAA is superseding Airworthiness Directive (AD) 2026-13- 09, which applied to all Pratt & Whitney Canada Corp. (P&WC) Model PW210A, PW210A1, and PW210S engines. AD 2026-13-09 required repetitive visual inspections of the turbine exhaust frame for cracks and, depending on the results of the inspections, replacement of the turbine exhaust frame. Since the FAA issued AD 2026-13-09, a manufacturer's analysis revealed that turbine exhaust frames manufactured from a certain material were less durable and more susceptible to developing cracks under thermal stress. This AD requires repetitive visual inspections of the turbine exhaust frame for cracks at different initial inspection thresholds than required by AD 2026-13-09 based on the material used during manufacture and, depending on the results of the inspections, replacement of the turbine exhaust frame. The FAA is issuing this AD to address the unsafe condition on these products.
2026-16640, Airworthiness Directives; Airbus Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Model H160-B helicopters. This proposed AD was prompted by a determination that a gap without fire-resistant sealant (sealant) may be present in the cargo bay near the fuel segregation box. This proposed AD would require inspecting for any missing sealant and, depending on findings, corrective action. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is cleaning up old rules by removing references to pilot certificates from over 50 years ago that no longer matter. This change affects pilots and aviation folks by making the rules clearer and easier to follow, with no extra costs or deadlines beyond the comment period ending July 27, 2026. It’s a simple, smart update to keep things fresh and relevant in the skies!
Next: 2026-13024, Airworthiness Directives; Airbus SAS Airplanes
The FAA wants all Airbus A330-200 series planes to fix or regularly check certain parts that keep the anti-ice system safe because some brackets have cracked or broken. They’re banning a specific repair and limiting part installations to keep flights safe. Airlines need to act soon and send feedback by August 13, 2026, which might cost some time and money but keeps everyone flying safely.
