FAA Tells Jet Engine Owners: Check Those Turbines Again
Published Date: 1/23/2025
Proposed Rule
Summary
The FAA is updating rules for certain General Electric jet engines to keep them safe, now including more engine models than before. If you own or operate these engines, you might need to make some fixes to avoid problems. The FAA wants your feedback before finalizing these changes, which could mean some extra work and costs soon.
Analyzed Economic Effects
2 provisions identified: 0 benefits, 2 costs, 0 mixed.
More GE Engine Models Covered
If you own or operate General Electric CF34-10E5 or CF34-10E5A1 engines, the FAA is adding those models to a proposed airworthiness directive that already covered CF34-10E2A1, CF34-10E6, CF34-10E6A1, CF34-10E7, and CF34-10E7-B engines with certain part-numbered high-pressure turbine (HPT) shroud/low pressure turbine (LPT) nozzle assemblies installed. That means the proposed safety rule now explicitly applies to those additional engine models.
Proposed AD Adds Compliance Burden
The FAA says the proposed airworthiness directive would require actions to address an unsafe condition and would impose an additional burden compared with the earlier proposal. If your aircraft has the affected engines with the specified HPT shroud/LPT nozzle assemblies, you may need to perform inspections or fixes, which could mean extra work and costs.

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.
2026-16803, Notice of Availability, Notice of Public Comment Period and Request for Comment on the Draft Environmental Assessment for Reditus Space ENOS Reentries in the Gulf of America
In accordance with the National Environmental Policy Act of 1969, as amended (NEPA) and FAA Order 1050.1G, FAA National Environmental Policy Act Implementing Procedures, the FAA is announcing the availability of and requesting comment on the Draft Environmental Assessment for Reditus Space ENOS Reentries in the Gulf of America (Draft EA).
2026-16795, Airworthiness Directives; The Boeing Company Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737 -300, -400, and -500 series airplanes. This proposed AD was prompted by reports of nuisance stick shaker activation while accelerating to cruise speed at the top of a climb due to frozen angle of airflow (AOA) sensor vanes. This proposed AD would require installing new external case heaters (ECHs) on the left and right AOA sensors, performing repetitive functional tests and applicable corrective actions, and accomplishing applicable concurrent actions. The FAA is proposing this AD to address the unsafe condition on these products.
2026-16804, Establishment of Class E Airspace; Trading Bay Production Airport, Trading Bay, AK
This action proposes to establish Class E airspace extending upward from 700 feet above the surface at Trading Bay Production Airport, Trading Bay, AK. This action would support the safety and management of instrument flight rules (IFR) operations at the airport.
