FAA Proposes Stricter Checks for Gulfstream G150s
Published Date: 6/9/2026
Proposed Rule
Summary
If you own or work with Gulfstream G150 airplanes, the FAA wants you to update your maintenance plans with new safety rules. These changes make inspections tougher to keep the planes safer. You’ll need to act before July 24, 2026, and while it might cost some time and money, it’s all about flying safer and smarter!
Analyzed Economic Effects
5 provisions identified: 1 benefits, 4 costs, 0 mixed.
G150 operators must update maintenance programs
If you operate Gulfstream G150 airplanes, you must revise your maintenance or inspection program to incorporate new or more restrictive airworthiness limitations specified in CAAI AD ISR I-05-2025-10-1 and Section 05-10-10 (Gulfstream G150 Maintenance Manual Revision 30, dated September 15, 2025). These changes address fatigue damage in the horizontal stabilizer/elevator systems and the nose landing gear actuator-to-strut attachment pin.
Estimated affected fleet and per-operator costs
The FAA estimates this proposed AD would affect 82 U.S.-registered Gulfstream G150 airplanes. The FAA estimates the total cost per operator for the retained actions from AD 2025-15-04 is $7,650 (90 work-hours x $85/hour) and the total cost per operator for the new proposed actions is $7,650 (90 work-hours x $85/hour).
Initial inspection deadlines (90 days / 3 months)
The proposed AD sets initial compliance timing: for tasks in CAAI AD ISR I-32-24-10-01R1 the initial compliance is at the applicable 'discard' interval or within 3 months after September 10, 2025, whichever occurs later. For tasks in CAAI AD ISR I-05-2025-10-1, initial compliance is at the applicable initial inspection interval or within 90 days after the effective date of this AD, whichever occurs later.
Reporting burden: ~1 hour per response
Inspection reporting associated with this rule is subject to the Paperwork Reduction Act under OMB Control Number 2120-0056. Public reporting for this collection is estimated to take approximately 1 hour per response and all responses are mandatory.
FAA: no significant small-entity impact
The FAA certified that this proposed AD "would not have a significant economic impact, positive or negative, on a substantial number of small entities" under the Regulatory Flexibility Act.

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.
2026-15239, 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.
2026-15006, Airworthiness Directives; Textron Aviation Inc. Airplanes
If you own a Textron B300 or B300C airplane, listen up! The FAA says you need to update your maintenance manuals to check the wings more often for cracks. This rule kicks in on August 10, 2026, so get ready to keep your plane safe without breaking the bank.
