Department of Transportation February 2025 – Federal Register Recent Federal Regulation Documents

Michelin North America, Inc. (MNA) has determined that certain Uniroyal Laredo AT and Laredo HT replacement tires do not fully comply with Federal Motor Vehicle Safety Standard (FMVSS) No. 139, New Pneumatic Radial Tires for Light Vehicles. MNA filed a noncompliance report dated November 3, 2023, and subsequently petitioned NHTSA (the "Agency") on November 28, 2023, for a decision that the subject noncompliance is inconsequential as it relates to motor vehicle safety. This document announces receipt of MNA's petition.

The FAA is superseding Airworthiness Directive (AD) 2023-11- 08, which applied to all Airbus SAS Model A330-841 and -941 airplanes. AD 2023-11-08 required maintenance actions, including a high-pressure valve (HPV) seal integrity test, repetitive replacement of the HPV clips, revision of the existing airplane flight manual (AFM), and implementation of updates to the FAA-approved operator's minimum equipment list (MEL). This AD was prompted by the determination that the replacement intervals required by AD 2023-11-08 must be reduced to address the unsafe condition. This AD continues to require the actions in AD 2023-11-08. This AD also reduces the HPV clip replacement intervals, requires an additional revision of the existing AFM for certain airplanes, and limits the installation of HPV clips, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

Notice is being given that the FAA is considering a request from the City of Melbourne to release 55.8 (+/-) acres at the Melbourne Orlando International Airport, Melbourne, FL from the conditions, reservations, and restrictions as contained in a Quitclaim Deed agreement between the FAA and the City of Melbourne, dated April 20, 1948. The release of property will allow the City of Melbourne to dispose of the property for non-aeronautical purposes.

This action proposes to amend United States Area Navigation (RNAV) Routes Q-64 and T-414, and establish RNAV Routes T-461 and T-463 in the eastern United States. This action supports FAA Next Generation Air Transportation System (NextGen) efforts to provide a modern RNAV route structure to improve the safety and efficiency of the National Airspace System (NAS).

The FAA proposes to supersede Airworthiness Directive (AD) 2017-14-14, which applies to all Airbus SAS Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2017-14-14 requires repetitive inspections for cracking in the cabin floor beam junction at certain fuselage frame locations, and repair if necessary. Since the FAA issued AD 2017-14-14, further analysis determined that the compliance times for the inspections must also be based on flight hours. This proposed AD would continue to require the actions in AD 2017-14-14, and would require revised compliance times and add a provision for optional modifications, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). 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 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by reports that very high frequency (VHF) radio frequencies transfer between the active and standby windows of the tuning control panel (TCP) without flightcrew input. The uncommanded frequency changes could result in missed communications between the flightcrew and Air Traffic Control. This proposed AD would require updating the TCP operational software (OPS) and performing a software configuration check. 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 Safran Helicopter Engines, S.A. (Safran) Model ARRIUS 2B2 engines. This proposed 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 proposed AD would require 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, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2023-20-03 for certain Austro Engine GmbH Model E4 and E4P engines. AD 2023-20-03 required repetitive engine oil analysis for aluminum content outside the acceptable limits and, if necessary, replacement of the pistons, piston rings, con-rods assembly, and crankcase or, as an alternative, replacement of the engine core. Since the FAA issued AD 2023-20-03, the manufacturer identified errors in the lists of affected engines and provided updated information, which prompted this AD. This AD retains the requirements of AD 2023-20-03, adds compliance times for additional affected engine serial numbers, and removes certain engine serial numbers from the applicability of the existing AD. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2023-26-05, which applies to certain Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. AD 2023-26-05 requires periodic replacement of affected titanium threaded bolts, a one-time inspection of the rudder mass balance arm and other elements of the rudder trim tab installation for correct attachment, damage (gouges), cracks, deformation, surface finish, and corrosion on any surrounding parts and, depending on findings, the accomplishment of applicable corrective actions. Since the FAA issued AD 2023-26-05, it was determined that some batches of titanium bolts had variations in the microstructure that could affect the fatigue characteristics. This proposed AD would require replacing affected short rudder-trim control rod assemblies with serviceable rudder-trim control rod assemblies having threaded steel bolts and would prohibit the installation of affected parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. 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 Airbus SAS Model A350-941 and -1041 airplanes. This proposed AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

This action proposes to revoke the Class E airspace at Pinecreek, MN. The FAA is proposing this action as the result of the instrument procedures being cancelled and the airport closing.

This rule amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures 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 for the safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

The FAA proposes to adopt a new airworthiness directive (AD) for certain ATRGIE Avions de Transport R[eacute]gional Model ATR42- 500 and ATR72-212A airplanes. This proposed AD was prompted by a report of potential use of improper material during the production of vertical tail plane (VTP) fittings. This proposed AD would require, for certain airplanes, an inspection for the material of affected fuselage-to-VTP fittings, an inspection report, and corrective actions, and, for certain other airplanes, part replacement, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2021-04- 18, which applied to Airbus Helicopters Model EC225LP helicopters. AD 2021-04-18 required repetitively inspecting the bearing in the swashplate assembly of certain main rotor (M/R) mast assemblies and, depending on the findings, replacing the M/R mast assembly. AD 2021-04- 18 also prohibited installing those M/R mast assemblies unless certain requirements were met. Since the FAA issued AD 2021-04-18, it was determined that additional M/R mast assemblies are affected by the same unsafe condition and that it is necessary to distinguish the affected part numbers between M/R mast assemblies and mast swashplate assemblies. This AD continues to require the actions specified in AD 2021-04-18 and adds additional part-numbered M/R mast assemblies and distinguishes the affected part numbers between M/R mast assemblies and mast swashplate assemblies, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also clarifies the possible consequences that could result from the unsafe condition and clarifies a requirement. The FAA is issuing this AD to address the unsafe condition on these products.
