Federal Aviation Administration – Federal Register Recent Federal Regulation Documents

The FAA is considering a proposal to change approximately 218 acres of airport land from aeronautical use to non-aeronautical use and to authorize the sale of airport property located at Lorain County Regional Airport, Elyria, Ohio. The aforementioned land is not needed for aeronautical use. The subject property is located north of Runway 7/25 and is currently being used for agricultural purposes. The intent is to sell the land to the Lorain County Port Authority to market the property for future light industrial uses.

This notice announces the FAA's withdrawal of the notice of intent to cancel Technical Standard Order (TSO-)C122a, "Equipment That Prevent Blocked Channels Used in Two-Way Radio Communications Due to Simultaneous Transmissions," dated June 18, 2012. Retaining TSO-C122a as an active TSO allows the continued design or production of articles authorized under the existing TSO approval. This withdrawal reflects the FAA's decision to maintain support for existing authorizations under TSO-C122a.

The FAA proposes to adopt a new airworthiness directive (AD) for Goodrich cabin attendant seats installed on Airbus SAS Model A330- 200 series, A330-200 Freighter series, A330-300 series, A330-841, A330- 941, A340-200 series, A340-300 series, A340-541, and A340-642 airplanes. This proposed AD was prompted by a report that track attachments used on certain part-numbered seats are non-compliant. This proposed AD would require replacing all seat track attachments and hardware and re-identifying the seat with a new part number. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2021-25- 14, which applied to all Airbus SAS Model A319-111, -112, -113, -114, - 115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, - 212, -213, -231, and -232 airplanes. AD 2021-25-14 required repetitive inspections for cracking at the wing manhole access panel attachment holes at certain wing skin panels, and corrective action if necessary. Since the FAA issued AD 2021-25-14, new investigation results determined that additional airplanes are subject to the unsafe condition and certain structural repair manual (SRM) tasks should not be used to accomplish repairs. This AD continues to require the actions in AD 2021-25-14. This AD also changes the applicability to both add and remove airplane models, updates the compliance times, and prohibits the use of certain SRM tasks for repair. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS-365N2, AS 365 N3, EC 155B, EC155B1, SA- 365N, and SA-365N1 helicopters. This AD was prompted by reports of loss of tightening torque between the upper ball bearing end and the main rotor (MR) servo-control. This AD requires inspecting the tightening torque and, depending on the results, taking corrective action. This AD also requires reporting information. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all DG Aviation GmbH (type certificate previously held by DG Flugzeugbau GmbH) Model DG-1000T gliders. This AD was prompted by reports of propeller separation. This AD requires revising the glider flight manual and installing "Motor INOP" placards to prohibit operation with the powerplant. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by a report of loss of control of an outboard aileron surface due to hydraulic fluid contaminating an electronic card of the flight control remote module (FCRM). This AD requires replacing any affected elevator FCRM and prohibits installing aileron or spoiler FCRMs in place of elevator or rudder FCRMs. This AD also limits the installation of FCRMs under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2024-25-06, which applies to all Airbus SAS Model A318-series airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, -133, - 151N, -153N, and -171N airplanes; Model A320-series airplanes; and Model A321-series airplanes. AD 2024-25-06 requires repetitive inspection of the main landing gear (MLG) doors, and, depending on findings, accomplishment of applicable corrective actions, and prohibits the installation of affected parts. The FAA has determined that replacing the MLG door is necessary to address the unsafe condition. This proposed AD would continue to require the actions in AD 2024-25-06 and would require replacing affected parts with serviceable parts. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company (Boeing) Model 737-600, -700, -700C, -800, - 900, and -900ER series airplanes. This proposed AD was prompted by a report of improper grinding of the inner diameter of the main landing gear (MLG) outer cylinders, resulting in possible heat damage to the outer cylinders. This proposed AD would require a records check or inspection to determine if an affected outer cylinder is installed and replacing all affected outer cylinders. The FAA is proposing this AD to address the unsafe condition on these products.

This action establishes Class E2 airspace extending upward from the surface above the New River Marine Corps Air Station (MCAS), Jacksonville, NC, as the air traffic control tower operates part-time. This action also removes the Class E4 airspace at New River MCAS (NCA), Jacksonville, NC, due to the current designated airspace no longer meeting the requirements of its designation. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.

The FAA proposes to adopt a new airworthiness directive (AD) for certain ATRGIE Avions de Transport R[eacute]gional Model ATR42- 500 and ATR72 airplanes. This proposed AD was prompted by an investigation indicating that an erroneous monitoring of the travel limitation unit (TLU) could occur when the airplane is flying above a certain speed as a result of the logic input from either air data computer (ADC) 1 or ADC2 input. This proposed AD would require modifying airplanes by installing one or two relays and associated wiring, and testing of the TLU monitoring logic. The FAA is proposing this AD to address the unsafe condition on these products.

This action amends Class D and Class E airspace at Coastal Carolina Regional Airport, New Bern, NC, due to the current designated airspace not properly containing instrument flight rule operations. Additionally, this action amends Class E4 airspace at Coastal Carolina Regional Airport, New Bern, NC, due to portions no longer meeting the requirements of its designation. Lastly, this action amends the Class E5 airspace that no longer meets the requirements for its specific designation due to the amendment or cancellation of Standard Instrument Approach Procedures. Controlled airspace is necessary for the safety and management of IFR operations in the area for existing instrument approaches.

This action modifies the Class E airspace extending upward from 700 feet above the surface at Wrangell Airport, Wrangell, AK; removes redundant Class E airspace extending upward from 1,200 feet above the surface; and makes administrative updates to the airport's legal description. In sum, these actions support the safety and management of instrument flight rules (IFR) operations at the airport.

The Federal Aviation Administration (FAA) is rescinding FAA Order 1050.1F, Environmental Impacts: Policies and Procedures in light of Executive Order 14154, Unleashing American Energy. The FAA is issuing new streamlined National Environmental Policy Act (NEPA) procedures, FAA NEPA Order 1050.1G, to align with amendments to the NEPA, 42 U.S.C. 4321 et seq., and to reflect the February 25, 2025 Interim Final Rule issued by the Council on Environmental Quality (CEQ) rescinding its regulations implementing NEPA. The new procedures maintain environmental amenities and protection and reduce regulatory delays that may impede aviation safety improvements and infrastructure development as well as integration of new entrant technologies. The Order is immediately effective upon publication and applies to all FAA actions that require environmental review and commence on or after the publication of this Notice. This Order does not apply to or alter any decisions made or final environmental documents issued prior to the effective date of this Order. Order 1050.1G promotes collaboration and efficiencies in the implementation of NEPA and modernizes the procedures for environmental reviews. This update is intended to provide clear, consistent, and simplified guidance for complying with the amended directives set forth in NEPA, and to the extent applicable, CEQ guidance that remains valid following the rescission of CEQ's NEPA implementing regulations. The FAA is providing an opportunity for public review and comment of this Order, which will inform future revisions.

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model EC 155B and EC155B1 helicopters. This proposed AD was prompted by a determination that the required forces to jettison the windows exceed the maximum jettisoning effort requirements and the development of a modification of the jettisonable windows. This proposed AD would require replacement of the jettisonable windows and seals on the sliding doors and fixed panels on the left-hand and right- hand sides. This proposed AD would also require the installation of new labels. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all Safran Helicopter Engines, S.A. (Safran) Model ARRIUS 2B2 engines. This AD was prompted by a manufacturer review of collected data from in- service engines that indicated the preference injector may clog over time caused by fuel coking, which decreases the permeability of the preference injector. This AD requires initial and repetitive non- extinguishing tests for engine flameout and replacement of the preference injector if necessary, a one-time modification (software upgrade) of the electronic engine control unit (EECU) and, for certain engines, repetitive replacements of the preference injector. The FAA is issuing this AD to address the unsafe condition on these products.

This action extends the prohibition against certain flight operations in the Kabul Flight Information Region (FIR) (OAKX) by all: U.S. air carriers; U.S. commercial operators; persons exercising the privileges of an airman certificate issued by the FAA, except when such persons are operating U.S.-registered aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except when the operator of such aircraft is a foreign air carrier, for an additional three years, from July 25, 2025, to July 25, 2028. FAA finds this action necessary to address continuing risks to persons and aircraft engaged in such flight operations.

The FAA is adopting a new airworthiness directive (AD) for all Embraer S.A. Model EMB-545 and EMB-550 airplanes. This AD was prompted by a jamming failure of the main door lock sensor. This AD requires repetitive main door sensor operational tests, repetitive lubrication of the main door sensor mechanism, and on condition actions. The FAA is issuing this AD to address the unsafe condition on these products.August 5, 2025.

The FAA proposes to supersede airworthiness directive (AD) 2024-09-02, which applies to all Leonardo S.p.a. Model AW169 helicopters. AD 2024-09-02 requires replacing certain aft float assemblies or, as an alternative, deactivating the emergency flotation system (EFS). AD 2024-09-02 also prohibits the installation of certain forward and aft float assemblies. Since the FAA issued AD 2024-09-02, the FAA has determined that replacing additional forward float and aft float life raft assemblies (also referred to as forward and aft float assemblies) is necessary. This proposed AD would retain all actions of AD 2024-09-02 and would also require replacing certain forward and aft float assemblies within 24 months or during the next accomplishment of a maintenance task. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation Model GVII-G500 and GVII-G600 airplanes. This proposed AD was prompted by a determination that new and more restrictive airworthiness limitations are necessary. This AD requires revising the maintenance or inspection program, as applicable to incorporate new and more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.

This rule establishes, amends, suspends, or removes Standard Instrument Approach Procedures (SIAPS) and associated Takeoff Minimums and Obstacle Departure procedures (ODPs) for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval to renew an information collection. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on April 8, 2025. The collection involves information collected which will be used by air carriers and by the FAA to adequately target its inspection resources for surveillance and make accurate risk assessments.

The FAA proposes to supersede Airworthiness Directive (AD) 2021-26-07, which applies to all Airbus Helicopters Model EC120B helicopters. AD 2021-26-07 requires performing repetitive inspections of the tail rotor (TR) hub body and, depending on the inspection results, replacing certain parts, and accomplishing further inspections. AD 2021-26-07 also requires for certain helicopters removing from service any bolt, washer, and nut installed on the TR hub body at certain life limits and replacing them with airworthy parts and accomplishing further inspections. Additionally, AD 2021-26-07 prohibits the installation of a certain part-numbered TR hub body unless certain requirements are met. Since the FAA issued AD 2021-26- 07, it was determined that modifying the link of the TR hub body and splined flange by adding red paint marks is necessary to enable the detection of any loss of tightening torque. This proposed AD would require the same repetitive inspections and corrective actions as AD 2021-26-07 and would require modification of the link of the TR hub body, which would be a terminating action for the repetitive inspections. The proposed AD would also require repetitive inspections of the red paint line added during the modification of the link of the TR hub body for alignment. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-9 and 787-10 airplanes. This proposed AD was prompted by reports of multiple supplier notices of escapement (NOEs) indicating that multiple cargo barrier fitting links were possibly manufactured with an incorrect titanium alloy material. This proposed AD would require a high frequency eddy current (HFEC) or handheld X-ray fluorescence (XRF) spectrometer inspection of the cargo barrier fitting link to determine the titanium alloy material, and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is withdrawing an NPRM that proposed to adopt a new airworthiness directive (AD) that would have applied to all Safran Helicopter Engines, S.A. (Safran) Model ARRIUS 2F and ARRIUS 2R engines. The NPRM was prompted by a manufacturer investigation that revealed certain high-pressure (HP) turbine blades may contain non- compliant porosity rates due to a change in the manufacturing process. The NPRM would have required replacement of affected HP turbine blades. Since the NPRM was issued, further investigation and tests demonstrated that the non-compliant rate of porosity has no impact on the use limit of the affected parts and the FAA has determined that the unsafe condition no longer exists. Accordingly, the NPRM is withdrawn.
