GE Engines Get New Crack Inspection Mandates
Published Date: 9/16/2025
Rule
Summary
If you own certain GE Aviation Czech engines, the FAA updated the rules to keep them safe. Instead of just one inspection, you now need to check the compressor case welds regularly and replace parts if cracks show up. You also have to share some inspection results with the maker, but the deadline to start these checks got a bit longer—saving you some time and hassle.
Analyzed Economic Effects
4 provisions identified: 1 benefits, 3 costs, 0 mixed.
Required compressor-case replacement if cracked
If a DVI finds any crack in the compressor case pad welds on the listed GEAC engine models, you must replace the compressor case. The AD keeps the replacement requirement from the prior rule and applies it when cracks are found.
Repetitive compressor-case inspections
If you own or operate GE Aviation Czech engines Model M601D-11, M601E-11, M601E-11A, M601E-11AS, M601E-11S, or M601F, the FAA now requires repetitive detailed visual inspections (DVIs) of the compressor case pad welds for any crack. This AD supersedes AD 2024-06-02, replacing the prior one-time DVI requirement with recurring checks.
Inspection results must be reported to manufacturer
The AD requires you to send certain inspection results from the compressor case DVIs to the engine manufacturer. You must share those specified inspection findings as part of compliance.
Extended compliance time to start inspections
The manufacturer determined the compliance time for the initial detailed visual inspection (DVI) from AD 2024-06-02 can be extended, and the FAA's superseding AD allows a longer deadline to start those inspections. This change gives owners/operators more time before the first inspection is due.

2026-15585, Requirements for Interference-Tolerant Radio Altimeter Systems
In July 2025, President Trump signed the One Big Beautiful Bill Act. Section 40002 of that law re-institutes the Federal Communications Commission's general auction authority and specifically directs the Commission to complete a system of competitive bidding for not less than 100 megahertz in the 3.98-4.2 gigahertz band (Upper C- band). This final rule supports the Federal Communications Commission's July 2026 Report and Order that makes 160 megahertz of the Upper C-band available for terrestrial wireless flexible use via a system of competitive bidding. To ensure safe, efficient, and reliable aviation operations in the presence of wireless signals in the C-band, the Federal Aviation Administration is issuing new regulations that require all radio altimeters to meet specific minimum performance requirements. These new radio altimeters must withstand interference from wireless signals in neighboring spectrum bands and continue to provide accurate altitude readings to both pilots and integrated aircraft safety systems. These regulations require all aircraft equipped with radio altimeters operating under part 121 and those aircraft with radio altimeters operating under part 129 with 30 or more passenger seats or a payload capacity of more than 7,500 pounds to comply with the minimum performance requirements by December 30, 2030, which is prior to the date the Federal Communications Commission authorizes the use of the Upper C-band for new wireless services, as stated in its Report and Order. All other aircraft equipped with radio altimeters that are required to comply with part 91, including aircraft operating under parts 125, 133, 135, 136, 137, 194, and all other aircraft operating under part 129 that are not subject to the initial deadline, must comply with the same minimum performance requirements on or before October 31, 2034.
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.
2025-04846, Extension of the Prohibition Against Certain Flights in the Territory and Airspace of Libya
The FAA is extending the ban on certain flights over Libya for three more years, until March 20, 2028. This affects U.S. airlines, commercial operators, and pilots with FAA certificates flying in Libyan airspace, due to ongoing safety risks. The rule also reminds everyone how to apply for special approvals or exemptions if needed.
2025-03853, Enforcement Policy Regarding “Drug and Alcohol Testing of Certificated Repair Station Employees Located Outside of the United States; Correction”
The FAA is giving repair stations outside the U.S. a break by delaying enforcement of new drug and alcohol testing rules until March 20, 2025. This means affected repair stations don’t have to worry about penalties if they aren’t fully following the updated rules just yet. The delay helps everyone get ready without rushing or extra costs.
