Federal Aviation Administration – Federal Register Recent Federal Regulation Documents

This action proposes to amend the Class E airspace at Nappanee, IN. The FAA is proposing this action as the result of an airspace review conducted due to the decommissioning of the Goshen very high frequency omnidirectional range (VOR) as part of the VOR Minimum Operational Network (MON) Program. The geographic coordinates of the Nappanee Municipal Airport, Nappanee, IN, would also be updated to coincide with the FAA's aeronautical database. This action will bring the airspace into compliance with FAA orders and support instrument flight rule (IFR) procedures and operations.

The FAA proposes updates to the AIP grant assurances to reflect recent legislative provisions in the FAA Reauthorization Act of 2024 as well as recently issued executive orders.

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, EC135T3, EC635T2+, MBB- BK 117 C-2, MBB-BK 117 D-2, and MBB-BK 117 D-3 helicopters. This proposed AD was prompted by a review of design data and the determination for recalculation of accumulated hoist boom cycles (cycles) and repetitive inspections. This proposed AD would require determining the total cycles of certain hoist boom assemblies, inspecting those hoist boom assemblies, and depending on the results, taking corrective action. This proposed AD would also prohibit installing those hoist boom assemblies unless certain requirements are met. These actions are 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 all Airbus Helicopters Model AS 365 N3, EC 155B, and EC155B1 helicopters. This proposed AD was prompted by reports of false engine fire warnings. This proposed AD would require replacing affected engine fire detectors and prohibit installing an affected engine fire detector or an engine that contains an affected engine fire detector, 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 supersede Airworthiness Directive (AD) 2024-06-02, which applies to all GE Aviation Czech s.r.o. (GEAC) Model M601D-11, M601E-11, M601E-11A, M601E-11AS, M601E-11S, and M601F engines. AD 2024-06-02 was prompted by a report of a crack on the centrifugal compressor case mount pad weld area caused by a non- conforming weld (lack of welding penetration). AD 2024-06-02 requires a one-time detailed visual inspection (DVI) of the compressor case pad welds for any crack, and replacement of the compressor case if necessary. Since the FAA issued AD 2024-06-02, the manufacturer determined that the compliance time for the DVI can be extended, and repetitive inspections of the centrifugal compressor case must be accomplished. This proposed AD would require performing repetitive DVIs of the compressor case pad welds for any crack, replacing the compressor case if necessary, and sending certain inspection results to the manufacturer, 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.

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, the FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval to renew information collection. The collection involves Aviation Maintenance Technician School (AMTS) applicants and certificate holders. The information to be collected will be used to ensure AMTS applicants and certificate holders meet applicable requirements prior to being certificated, and on an ongoing basis following FAA certification.

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A318, A319, A320, and A321 series airplanes. This proposed AD was prompted by a heavy maintenance check that found elongation on the upper section of the vertical member's assembly at the frame (FR) 24A cargo panel sub-structure. This proposed AD would require a check for certain repairs, and as applicable, repetitive detailed visual inspections of the vertical member's upper part and the upper fittings at FR 24A in the forward cargo compartment and corrective actions. 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 Leonardo S.p.a. Model A109C, A109E, A109S, and AW109SP helicopters.

This proposed AD was prompted by a report that cracks were found following fatigue tests for the new lower wing cover material on airplanes equipped with sharklets. This proposed AD would require repetitive inspections for discrepancies, and corrective action, 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) 2020-20-17 and AD 2021-15-05 for all General Electric Company (GE) Model GE90- 110B1 and GE90-115B engines. AD 2020-20-17 prohibits dispatch of an airplane if certain status messages are displayed on the engine indicating and crew alerting system (EICAS) and if certain conditions are present; and as terminating action, requires revision of the existing FAA-approved minimum equipment list (MEL) by incorporating the dispatch restrictions into the MEL. AD 2021-15-05 requires initial and repetitive replacement of the full authority digital engine control (FADEC) integrated circuit (MN4) microprocessor. Since the FAA issued AD 2020-20-17 and AD 2021-15-05, the manufacturer has developed a software revision for the electronic engine control (EEC) FADEC that further mitigates the unsafe condition. This AD retains all the actions of AD 2020-20-17 and AD 2021-15-05, and also requires upgrading the EEC FADEC software to an EEC FADEC software version eligible for installation as a terminating action. The FAA is issuing this AD to address the unsafe condition on these products.
