Gulfstream Owners Told to Check Engine Pins
Published Date: 7/2/2026
Rule
Summary
If you own or operate Gulfstream G700 or G800 airplanes, listen up! The FAA found a broken pin on the engine mount caused by a missing part, so they’re requiring inspections and fixes to keep flights safe. This rule kicks in July 17, 2026, and while it might cost some time and money, it’s all about making sure your plane stays rock solid.
Analyzed Economic Effects
4 provisions identified: 1 benefits, 3 costs, 0 mixed.
Immediate inspections required before flight
If you own or operate certain Gulfstream GVIII-G700 or GVIII-G800 airplanes, you must do a visual inspection of the upper surface of the engine mount at the hollow pin head interface and inspect thrust strut mount hardware before further flight. This AD is effective July 17, 2026, and repeats requirements that were issued as Emergency AD 2026-13-51 on June 18, 2026.
Estimated inspection cost per airplane
The FAA estimates the inspection will take 20 work-hours at $85 per hour, costing $1,700 per airplane. The FAA estimates this AD affects 37 U.S.-registered airplanes, for a total estimated inspection cost to U.S. operators of $62,900.
Warranty may reduce operator costs
The FAA notes the manufacturer has said some or all costs of this AD may be covered under warranty, which could reduce the cost impact on affected operators. The FAA has not provided specific amounts for on-condition corrective actions.
No special flight permits allowed
Special flight permits under 14 CFR 21.197 and 21.199 are not allowed for affected airplanes, meaning operators cannot use special-permit flights to defer or move aircraft pending compliance. This restriction is part of the AD's required actions.

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 making sure certain Boeing 787 airplanes stay safe by fixing door handles that have been coming loose during pre-flight checks. Starting August 6, 2026, airlines must install new parts and do inspections to keep these doors secure. This update helps prevent safety issues without causing big delays or costs.

If you own certain Rolls-Royce Deutschland Trent XWB engines, this new rule means you’ll need to check the main fuel hose more often for cracks, dents, or wear. Some engines require one-time inspections, while others need regular check-ups to keep flying safely. These changes start July 17, 2026, and could mean some repair costs if parts need replacing.
