FAA Targets Gaps in Airbus Chopper Fireproofing Sealant
Published Date: 8/14/2026
Proposed Rule
Summary
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.
Analyzed Economic Effects
2 provisions identified: 1 benefits, 1 costs, 0 mixed.
Reduces cargo-bay fire risk
The FAA is proposing this AD because a gap without fire‑resistant sealant may be present in the cargo bay near the fuel segregation box on certain H160-B helicopters. The required inspections and corrective sealant application (per EASA AD 2025-0279, dated December 10, 2025) aim to preserve the cargo compartment's fire‑resistant characteristic and avoid reduced control of the helicopter in case of fire.
Mandatory cargo-bay sealant inspection
If you operate an Airbus Helicopters Model H160-B delivered before October 21, 2025, the FAA proposes you must inspect the cargo bay frame (right side upper corner) for any missing fire‑resistant sealant. The FAA estimates the inspection takes 1 work-hour (cost $85 per helicopter) and would affect 13 U.S.-registered helicopters; if missing sealant is found, applying sealant is estimated at $163 ($85 labor + $78 parts) per helicopter.

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.
2026-16659, Airworthiness Directives; Gulfstream Aerospace LP (Type Certificate Previously Held by Israel Aircraft Industries, Ltd.) Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Gulfstream Aerospace LP Model Gulfstream 200 and Galaxy 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.
2026-16641, Airworthiness Directives; Airbus Helicopters
The FAA is superseding Airworthiness Directive (AD) 2023-25- 14, which applied to certain Airbus Helicopters Model EC130T2 helicopters. AD 2023-25-14 revised the procedures for inspecting the vibration level on the tail rotor drive shaft and, depending on these results, required replacing certain parts. Since the FAA issued AD 2023-25-14, the manufacturer developed a modification of the rear drive shaft, sliding flange, and equipped splined sleeve. This AD requires installing this modification and repetitively inspecting the vibration level of the tail rotor drive shaft. This AD also prohibits the installation of certain parts and prohibits the performance of a balance correction unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products.
