The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC225LP helicopters. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD requires revising the airworthiness limitations section (ALS) of the existing maintenance manual (MM) or instructions for continued airworthiness (ICAs) and the existing approved maintenance or inspection program, as applicable. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA proposes to supersede Airworthiness Directive (AD) 2020-24-07, which applies to certain Airbus Helicopters Model AS350B3, EC130B4, and EC130T2 helicopters. AD 2020-24-07 requires modifying and inspecting the pilot's and co-pilot's throttle twist grip (twist grip) for proper operation. Since the FAA issued AD 2020-24-07, Airbus Helicopters developed another modification of the twist grip and additional corrective actions for helicopters already modified. This proposed AD was prompted by reports of the engine remaining in idle when the twist grip was turned from the "IDLE" mode to the "FLIGHT" mode. This proposed AD would retain the actions required by AD 2020-24- 07 and mandate an additional modification, which would constitute terminating action for the repetitive inspections. This proposed AD would also expand the helicopter applicability, propose additional requirements for certain helicopters, and would prohibit installing affected microswitches or an affected twist grip with the affected microswitch. The FAA is proposing this AD to address the unsafe condition on these products.
The FAA proposes to supersede Airworthiness Directive (AD) 2022-23-08, which applies to all Viking Air Limited (Viking) Model DHC- 3 airplanes. AD 2022-23-08 requires a visual inspection of the stabilizer actuator to confirm that the stabilizer actuator lock ring is present, correctly seated in the groove in the upper housing, and engaged in the clamp nut, applicable corrective actions, application of a torque seal, and sending the inspection results to the FAA. This proposed AD would require repetitively inspecting the stabilizer actuator to confirm that the stabilizer actuator lock ring is present, correctly seated in the groove in the upper housing, and engaged in the clamp nut; taking applicable corrective actions; applying a witness mark (torque seal); and installing a secondary retention feature as terminating action for the repetitive inspections. This proposed AD would also prohibit the installation of any stabilizer actuator unless it is a serviceable part. 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 Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. This proposed AD was prompted by a report of an inaccurate flight director calculation on approach. This proposed AD would require incorporating a temporary revision into the existing airplane flight manual (AFM) for the affected airplanes, which revises the Abnormal Procedures Section. The FAA is proposing this AD to address the unsafe condition on these products.
This action revises an earlier notice of proposed rulemaking (NPRM) that the FAA published in Federal Register on March 20, 2025, by correcting the geographic coordinates of a boundary point in proposed restricted areas R-5305A, R-5305B, and R-5305C; Camp Lejeune, NC. This action continues to propose restricted areas R-5307A, R-5307B, and R- 5307C; Cherry Point, NC. The purpose of this proposal is to create additional restricted area airspace to connect restricted area R-5003, R-5004, and R-5306 complexes to contain hazardous activities such as weapon deployment, non-eye safe lasers, and artillery within larger contiguous restricted area airspace that is required to realistically simulate essential training mission tasks.
This action proposes to amend the Class E airspace at Lacon, IL. The geographic coordinates of the Marshall County Airport, Lacon, IL, 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 Bradford very high frequency omnidirectional range (VOR) as part of the VOR Minimum Operational Network (MON) Program. This action would bring the airspace into compliance with FAA orders and support instrument flight rule (IFR) procedures and operations.
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH Model MBB-BK 117 D-2 and MBB-BK 117 D-3 helicopters. This proposed AD was prompted by reports of airspeed and altitude indication errors. This proposed AD would require revising the existing rotorcraft flight manual supplement (RFMS) for the helicopter and replacing the air conditioning system (ACS) condenser outlet grids with ACS condenser outlet covers, and would prohibit installing ACS condenser outlet grids. 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 H[eacute]licopt[egrave]res Guimbal (HG) Model Cabri G2 helicopters. This proposed AD was prompted by reports of cracked main rotor swashplates (swashplates). This proposed AD would require repetitively inspecting certain swashplates for cracks and, depending on the results, removing and replacing each cracked swashplate. This proposed AD would also prohibit installing an affected swashplate unless it has passed the proposed inspection requirements. The FAA is proposing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) Model CF34-8C1, CF34-8C5, CF34- 8C5A1, CF34-8C5A2, CF34-8C5A3, CF34-8C5B1, CF34-8E2, CF34-8E2A1, CF34- 8E5, CF34-8E5A1, CF34-8E5A2, CF34-8E6, and CF34-8E6A1 engines. This AD was prompted by a predicted reduction in the cyclic life of the combustion chamber assembly (CCA) forward flange. This AD requires fluorescent penetrant inspections (FPIs) of the CCA for any indications and replacement if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
This action corrects a final rule published by the FAA in the Federal Register on June 3, 2025. That final rule amended Class D airspace extending upward from the surface to and including 2,500 feet MSL within a 4.5-mile radius of William P. Gwinn Airport in Jupiter, FL, beginning at the 205[deg] bearing from the airport clockwise to the 145[deg] bearing, thence to the beginning point. However, there was an administrative error in the airspace description, with the incorrect state listed. Therefore, this action corrects that final rule by revising the airspace header to the correct state.
This action amends Class D airspace and establishes Class E airspace extending upward from the surface above Little Rock AFB, Little Rock, AR, as the air traffic control tower will shift to part- time operations. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at this airport.
The FAA proposes to supersede Airworthiness Directive (AD) 2024-22-02, which applies to certain Airbus SAS Model A330-200, -200 Freighter, -300, -800, and -900 series airplanes. AD 2024-22-02 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2024-22-02, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would continue to require certain actions in AD 2024- 22-02 and would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.
The FAA proposes to supersede Airworthiness Directive (AD) 2023-25-09, which applies to all Airbus SAS Model A318, A319, A320, A321, A330-200, A330-200 Freighter, A330-300, A330-800, A330-900, A340- 200, A340-300, A340-500, and A340-600 series airplanes. AD 2023-25-09 requires replacing SafeLav gaseous oxygen containers (SLGOCs) affected by a production deficiency and prohibiting the installation of affected SLGOCs. Since the FAA issued AD 2023-25-09, a new airplane model has been certified, on which affected parts could be installed in service. This proposed AD would continue to require the actions in AD 2023-25-09 and would add airplanes to the applicability. The FAA is proposing this AD to address the unsafe condition on these products.
Draft FAA Notice N 8100.20 would incorporate the requirements of the FAA Reauthorization Act of 2024, which directs the FAA to ensure that each ODA holder has in effect a recurrent training program for all ODA unit personnel.
This action proposes to establish Class E domestic en route airspace (Class E6) within a designated landmass and within 12 miles from a designated coastline associated with the state of Alaska to facilitate the vectoring of instrument flight rules (IFR) aircraft on direct routes where the current en route structure is insufficient or improper within the proposed airspace area. Due to redundancy, this action also proposes to remove two Class E6 airspace areas, remove two Class E airspace areas extending upward from 1,200 feet above the surface, and modify 101 Class E airspace areas extending upward from 700 feet or more above the surface of the earth (Class E5) to remove any portion extending upward from 1,200 feet above the surface due to redundancy. Finally, this action proposes administrative amendments to the legal descriptions of 48 Class E5 airspace areas. This action would support IFR operations while enhancing the safety and management of aircraft operations within the National Airspace System (NAS).
This action proposes to amend Very High Frequency Omnidirectional Range (VOR) Federal Airway V-300 due to the planned relocation of the Wiarton, Ontario (ON), Canada, VOR/Distance Measuring Equipment (VOR/DME) navigational aid (NAVAID).

The FAA proposes to supersede Airworthiness Directive (AD) 2024-01-01, which applies to certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. AD 2024-01-01 requires repetitive general visual inspections (GVIs) of the area under all lavatory washbasins for evidence of intermittent and active leaks at the faucet control module (FCM) and applicable on-condition actions. The FAA has determined that the affected FCMs must be replaced with an improved design FCM to address the unsafe condition. This proposed AD would continue to require the actions of AD 2024-01-01 and would require replacing the FCM as terminating action for the repetitive GVIs, performing a leak test, installing moisture management devices, and performing applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
The FAA proposes to supersede Airworthiness Directive (AD) 2013-08-11, which applies to certain The Boeing Company Model 737-900 and -900ER series airplanes. AD 2013-08-11 requires repetitive inspections for cracking of the fuselage skin along chem-mill steps at certain crown skin and shear wrinkle areas and repair if necessary. Since the FAA issued AD 2013-08-11, the FAA has determined that the compliance times are not adequate. This proposed AD would continue to require the actions in AD 2013-08-11 but at reduced compliance times and would require post-modification inspections if an optional modification is accomplished. 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 a report of multiple instances of loss of transponder for airplanes entering airspace in the presence of continuous wave (CW) interference, where the transponder did not meet the minimum operational performance standards (MOPS) requirement for transponder response. This proposed AD would require replacing the left and right integrated surveillance system processor unit (ISSPU) hardware. The FAA is proposing this AD to address the unsafe condition on these products.
These special conditions are issued for the The Boeing Company (Boeing) Model 747-8 series airplane. This airplane, as modified by Boeing, will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. This design feature is the installation of stairs for flightcrew to access the forward and aft lower lobe compartments during flight. These compartments will have two main functions: storage of service items and that of a Class C cargo compartment. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
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.
