Amendment of Class D and Class E Airspace; Elkhart and Goshen, IN
Document Number: 2025-11925
Type: Proposed Rule
Date: 2025-06-27
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to amend the Class D and Class E airspace at Elkhart, IN, and the Class E airspace at Goshen, IN. The geographic coordinates of the Elkhart Municipal Airport, Elkhart, IN, and the Goshen Municipal Airport, Goshen, IN, would also be updated to coincide with the FAA's aeronautical database. The FAA is proposing this action as the result of airspace reviews conducted due to the decommissioning of the Goshen very high frequency omnidirectional range (VOR) as part of the VOR Minimum Operational Network (MON) Program. This action will bring the airspace into compliance with FAA orders and supports instrument flight rule (IFR) procedures and operations.
Airworthiness Directives; Airbus Helicopters
Document Number: 2025-11697
Type: Proposed Rule
Date: 2025-06-25
Agency: Federal Aviation Administration, Department of Transportation
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.

Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2025-11690
Type: Proposed Rule
Date: 2025-06-25
Agency: Federal Aviation Administration, Department of Transportation
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.
Airworthiness Directives; CFM International, S.A. Engines
Document Number: 2025-11689
Type: Proposed Rule
Date: 2025-06-25
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain CFM International, S.A. (CFM) Model LEAP-1A23, LEAP-1A24, LEAP-1A24E1, LEAP-1A26, LEAP-1A26CJ, LEAP-1A26E1, LEAP-1A29, LEAP- 1A29CJ, LEAP-1A30, LEAP-1A32, LEAP-1A33, LEAP-1A33B2, and LEAP-1A35A engines. This proposed AD was prompted by a report of multiple aborted takeoffs and air turn-backs (ATBs) caused by high-pressure compressor (HPC) stall, which was induced by high levels of non-synchronous vibration (NSV). Additional manufacturer investigation revealed that wear on the No. 3 bearing spring finger housing can lead to high levels of NSV. This proposed AD would require initial and repetitive calculations of the levels of NSV, inspection of the stage 2 high- pressure turbine (HPT) nozzle assembly honeycomb and HPT stator stationary seal honeycomb and, depending on the results of the calculations and inspections, replacement of certain parts. This AD also requires replacement of certain No. 3 bearing spring finger housings at a certain time. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Safran Helicopter Engines
Document Number: 2025-11665
Type: Proposed Rule
Date: 2025-06-25
Agency: Federal Aviation Administration, Department of Transportation
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.
