FAA Orders Weld Checks on Czech Engines for Safer Skies
Published Date: 4/23/2025
Proposed Rule
Summary
If you own or operate GE Aviation Czech M601 engines, listen up! The FAA wants you to keep checking the compressor case welds regularly for cracks and replace parts if needed. They’re giving you more time between inspections, but you’ll need to send inspection results to the manufacturer to keep everyone safe and sound.
Analyzed Economic Effects
3 provisions identified: 0 benefits, 2 costs, 1 mixed.
Repetitive Visual Inspections Required
If you own or operate GE Aviation Czech Model M601D-11, M601E-11, M601E-11A, M601E-11AS, M601E-11S, or M601F engines, the FAA proposes a new rule requiring repetitive detailed visual inspections (DVI) of the compressor case pad welds for any crack. This proposed AD would supersede AD 2024-06-02 and incorporate by reference a related EASA AD that specifies the repetitive inspection requirements.
Compressor Case Replacement If Cracked
The proposed rule requires you to replace the centrifugal compressor case if a DVI finds any crack in the compressor case pad weld area on the listed M601 engine models. The requirement to replace the compressor case is part of the FAA’s proposed superseding AD to address the unsafe condition identified in AD 2024-06-02.
Inspection Results Must Be Sent to Manufacturer
Under the proposed AD you must send certain inspection results from the compressor case pad weld DVIs to the manufacturer as specified in the incorporated EASA AD. The FAA proposes this reporting requirement as part of the rule that supersedes AD 2024-06-02.

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.
2026-17551, Airworthiness Directives; Airbus SAS Airplanes
The FAA is superseding Airworthiness Directive (AD) 2024-25- 06, which applied to all Airbus SAS Model A318 and A320 series airplanes; and Model A319-111, -112, -113, -114, -115, -131, -132, - 133, -151N, -153N, and -171N airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -252N, -253N, -271N, -272N, - 251NX, -252NX, -253NX, -271NX, -272NX, and -253NY airplanes. AD 2024- 25-06 required repetitive inspections of the main landing gear (MLG) door actuators and, depending on findings, accomplishment of applicable corrective actions, and prohibited the installation of affected parts. Since the FAA issued AD 2024-05-06, the FAA determined that replacing the MLG door actuators is necessary to address the unsafe condition, and the applicability and definition of an affected part must be expanded. This AD continues to require the actions in AD 2024-25-06, requires replacing affected parts with serviceable parts, and expands the applicability and definition of an affected part. The FAA is issuing this AD to address the unsafe condition on these products.
2026-17552, Airworthiness Directives; Airbus SAS Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A320-211, -212, -214, -216, -231, -232, and - 233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. This AD was prompted by a fatigue test that identified cracks in the forward and aft upper corner of the bulk cargo door. This AD requires a rototest inspection for cracks and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.

The Coast Guard wants to set up special rules for boats in Ludington Harbor Channel and Pere Marquette Lake to keep everyone safe because more boats are crowding the area. This will help protect people, the environment, and property from accidents. If you’re a boat operator or local resident, you might see new navigation limits soon and can share your thoughts before the rules are final.
