The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Model AS 332L2 and EC 225LP helicopters. This proposed AD was prompted by reports of overlengthened and deformed attachment bolts installed on the link of the main gearbox (MGB) suspension bar attachment bracket. This proposed AD would require replacing certain attachment bolts on the MGB suspension bar fittings, inspecting the removed bolts, and reporting the results of this inspection to Airbus Helicopters. The FAA is proposing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350D, AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters. This AD was prompted by a report of a sliding door that was locked in the open position detaching from the helicopter during flight. This AD requires modifying certain upper rail rollers, installing a label on each sliding door, and prohibits installing affected upper rail rollers or a door having an affected upper rail roller. These actions are 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.
The FAA is adopting a new airworthiness directive (AD) for Cameron Balloons Ltd. (Cameron) fuel cylinders fitted with certain pressure relief valve (PRV) adaptors on hot air balloons. This AD was prompted by the discovery of cracks on the upper hex portion of PRV adaptors. This AD requires repetitively visually checking the PRV adaptor for cracks and removing any fuel cylinder with a cracked PRV adaptor from service. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is superseding Airworthiness Directive (AD) 2023-26- 05, which applied to certain Pilatus Aircraft Ltd. (Pilatus) Model PC- 24 airplanes. AD 2023-26-05 required 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 AD requires replacing affected short rudder-trim control rod assemblies with serviceable rudder-trim control rod assemblies having threaded steel bolts and prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA proposes to adopt a new airworthiness directive (AD) for certain Pratt & Whitney (PW) Model F117-PW-100, PW2037, PW2037D, PW2037M, PW2040, PW2040D, PW2043, PW2143, and PW2643 engines. This proposed AD was prompted by an updated analysis of an event involving an International Aero Engines, LLC (IAE LLC) Model PW1127GA-JM engine, which experienced a high-pressure compressor (HPC) 7th-stage integrally bladed rotor (IBR-7) separation that resulted in an engine shutdown and aborted takeoff. This proposed AD would require repetitive angled ultrasonic inspections (AUSIs) of certain high-pressure turbine (HPT) 1st-stage disks and turbine hubs for any crack indications, and if necessary, removal from service and replacement, and removal from service of certain HPT lenticular seal assemblies. The FAA is proposing this AD to address the unsafe condition on these products.
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 supersede Airworthiness Directive (AD) 2024-10-13, which applies to all Airbus Helicopters Model AS332C, AS332C1, AS332L, AS 332L1, AS 332L2, and EC 225LP helicopters. AD 2024- 10-13 requires visually inspecting the bowls of the left-hand (LH) and right-hand (RH) fuel filters for any cracks and seepage. Depending on the inspection results, AD 2024-10-13 requires removing an affected fuel filter from service and replacing that part. AD 2024-10-13 also allows a certain fuel filter to be installed on any helicopter if certain actions are accomplished. Since the FAA issued AD 2024-10-13, additional inspection criteria was developed. This proposed AD would require the same actions as AD 2024-10-13 but would remove some helicopters from the applicability, add an inspection of the inner surface of the fuel filter bowls, and revise the tightening torque. The FAA is proposing this AD to address the unsafe condition on these products.
This action changes the referenced Notice to Air Missions to Notice to Airmen in the airspace description for both the Class D and E airspace at Northeast Philadelphia Airport, Philadelphia, PA. This action does not change the airspace boundaries or operating requirements.
This action amends Class D airspace and establishes Class E airspace extending upward from the surface above Robins AFB, Warner Robins, GA, 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.
This action removes Class D and E4 airspace at Phillips Army Airfield (AAF), Aberdeen, MD, due to the closure of the air traffic control tower. This action establishes Class E2 airspace extending upward from the surface above Phillips AAF at the request of the United States Army to provide the required airspace for Instrument Flight Rules (IFR) operations at Phillips AAF. This action also amends Class E5 airspace to accommodate the decommissioning of the Aberdeen non-directional radio beacon (NDB) and cancellation of the associated instrument approach procedures. Controlled airspace is necessary for the safety and management of IFR operations in the area for existing instrument approaches.
