The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model EC225LP helicopters. This proposed AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This proposed AD would require 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, 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 action establishes Class E airspace extending upward from 700 feet above the surface at Stanford/Biggerstaff Field, Stanford, MT. This action supports the airport's transition from visual flight rules (VFR) to instrument flight rules (IFR) operations.
This action amends Very High Frequency Omnidirectional Range (VOR) Federal Airways V-5, V-47, V-97, V-128, V-275, and V-517, and United States (U.S.) Area Navigation (RNAV) Route T-315; and revokes VOR Federal Airway V-19. The FAA is taking this action due to the planned decommissioning of the VOR portion of the Cincinnati, KY (CVG), VOR/Tactical Air Navigation (VORTAC) navigational aid (NAVAID). The Cincinnati VOR is being decommissioned in support of the FAA's VOR Minimum Operational Network (MON) program.
This action proposes to establish restricted areas R-5305A, R- 5305B, and R-5305C; Camp Lejeune, NC; and 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 establishes Class E airspace extending upward from 700 feet above the surface for Sunbury Fire Department Heliport, Sunbury, NC, by adding airspace for the heliport, which accommodates new area navigation (RNAV) global positioning system (GPS) standard instrument approach procedures serving the heliport. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at this heliport.
The FAA is adopting a new airworthiness directive (AD) for certain Pratt & Whitney Canada Corp. (P&WC) Model PW535E and PW535E1 engines. This AD was prompted by a manufacturer design review that indicated certain flange bolts securing the gas generator case and turbine support case are susceptible to cracking at their current low- cycle fatigue (LCF) life. This AD requires repetitive borescope inspections (BSI) of the gas generator case to turbine support case retaining bolts for evidence of bolt cracks, bolt fracture, missing bolts, or loose bolts and replacement, if necessary, as specified in a Transport Canada 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 all The Boeing Company Model 777-200, -200LR, -300, -300ER, and 777F series airplanes. This AD was prompted by a report of a 5-inch crack on the upper wing skin at a certain wing station of the right wing. This AD requires repetitive inspections for cracking of the upper wing skin common to certain fasteners and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for all ATR--GIE Avions de Transport R[eacute]gional Model ATR42 and ATR72 airplanes. This AD was prompted by a report of a manufacturing defect identified in the lavatory fire extinguisher. This defect could potentially result in leakage at the eutectic tip, leading to a loss of pressure in the cylinder, making fire extinguishing capabilities ineffective. This AD requires an inspection (i.e., weight check) and replacement, as applicable, of certain lavatory compartment fire extinguishers, and also prohibits the installation of affected parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference (IBR). The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-800 series airplanes. This AD was prompted by a determination that the compliance time for the initial ultrasonic inspection required by AD 2019-11-06 is insufficient for certain airplanes. This AD requires reducing the compliance time for the ultrasonic inspection of the skin under the drag link assembly. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA proposes to supersede Airworthiness Directive (AD) 2022-25-51, which applies to all Airbus Canada Limited Partnership Model BD-500-1A10 and Model BD-500-1A11 airplanes. AD 2022-25-51 requires revising the Limitations section of the existing airplane flight manual (AFM) to include a new warning and a new limitation. Since the FAA issued AD 2022-25-51, updated primary flight control computer (PFCC) software has been developed to address the unsafe condition. This proposed AD would continue to require the actions in AD 2022-25-51, require installing the updated PFCC software, which terminates the AFM revision, and remove airplanes from the applicability, as specified in a Transport Canada 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) 2019-05- 02, which applied to certain Rolls-Royce Deutschland Ltd & Co KG (RRD) (type certificate previously held by Rolls-Royce plc) Model RB211-Trent 970-84 and RB211-Trent 972-84 engines. AD 2019-05-02 required repetitive inspections of the drains mast for any crack and replacement or repair of the drains mast if necessary. Since the FAA issued AD 2019-05-02, the manufacturer has developed a modification (improved drains mast and drains support bracket), which the FAA has determined mitigates the unsafe condition. This AD was prompted by cracks found in the transition duct area of the drains mast. This AD requires modification with improved drains mast and drains support bracket. 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 all Safran Helicopter Engines, S.A. (Safran) Model ARRIUS 2F and ARRIUS 2R engines. This proposed AD 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. This proposed AD would require replacement of affected HP turbine blades, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. 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 General Electric Company (GE) Model CT7-2E1 engines. This AD was prompted by a revised analysis using an updated stress model, which calculated that the actual life limit of the CT7-2E1 stage 2 turbine aft cooling plate is less than the current life limit. This AD requires revision of the airworthiness limitations section (ALS) of the existing CT7-2E1 engine maintenance manual (EMM) and the operator's existing approved maintenance program or inspection program, as applicable, to incorporate a reduced life limit for this part. The FAA is issuing this AD to address the unsafe condition on these products.

This action proposes to amend Very High Frequency Omnidirectional Range (VOR) Federal Airways V-55, V-100, and V-277. The FAA is proposing this action due to the planned decommissioning of the VOR portion of the Keeler, MI (ELX), VOR/Distance Measuring Equipment (VOR/DME) navigational aid (NAVAID). The Keeler VOR is being decommissioned in support of the FAA's VOR Minimum Operational Network (MON) program.
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.
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC 155B, EC155B1, SA-365N, SA-365N1, AS-365N2, and AS 365 N3 helicopters. This AD prompted by an engine compartment fire where the upper stiffener of the central firewall in the engine compartment was found damaged. This AD requires replacing the aluminum central firewall stiffener with a titanium central firewall stiffener and prohibits installing an aluminum central firewall stiffener. 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.
This action proposes to amend the Class E airspace at Payson, AZ. The FAA is proposing this action as the result of airspace reviews conducted as part of the decommissioning of the Payson non directional beacon (NDB). This action would also update the name and geographic coordinates of the airport 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.
This action proposes to revoke Jet Route J-534 and Very High Frequency Omnidirectional Range (VOR) Federal Airway V-349, amend VOR Federal Airways V-23 and V-165, and establish Canadian Area Navigation (RNAV) Route T-645 in the Northwestern United States. The FAA is proposing this action due to the pending decommissioning of the VOR portion of the Whatcom, WA, VOR/Tactical Air Navigation (VORTAC) navigational aid (NAVAID). The VOR portion of the Whatcom VORTAC is being decommissioned in support of the FAA's VOR Minimum Operational Network (MON) program. There are two airways that use the naming convention of V-23. One is located in the state of Hawaii and the other is located in the state of California. This action proposes to affect the V-23 in the state of California and does not propose any changes to the V-23 in the state of Hawaii.
These special conditions are issued for a supplemental type certificate (STC) to install a digital systems architecture on certain transport category airplanes. These airplanes, as modified by Universal Avionics, 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 a digital systems architecture that will allow increased connectivity to and access from external network sources (e.g., operator networks, wireless devices, internet connectivity, service provider satellite communications, electronic flight bags, etc.) to the airplane's previously isolated electronic assets (networks, systems, and databases). 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.
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This proposed AD was prompted by a determination that certain master minimum equipment list (MMEL) items do not comply with MMEL certification requirements. This proposed AD would require revising the operator's existing FAA- approved minimum equipment list (MEL), 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 adopting a new airworthiness directive (AD) for all Bombardier, Inc., Model BD-700-2A12 airplanes. This AD was prompted by the discovery that a partial loss of thrust after an engine failure during a required navigation performance authorization required (RNP- AR) approach under certain weight, altitude and temperature (WAT) conditions, may lead to a descent below the specified path guidance. This AD requires a revision to the existing airplane flight manual (AFM), to incorporate updated WAT tables for RNP-AR approach operations. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for certain Pratt & Whitney (PW) Model PW1519G, PW1521G, PW1521GA, PW1521G- 3, PW1524G, PW1524G-3, PW1525G, PW1525G-3, PW1919G, PW1921G, PW1922G, PW1923G, and PW1923G-A engines with a certain high-pressure compressor (HPC) 7th-stage axial rotor installed. This AD was prompted by an analysis of an event involving an International Aero Engines, LLC (IAE LLC) Model PW1127GA-JM engine, which experienced an HPC 7th-stage integrally bladed rotor (IBR-7) separation that resulted in an aborted takeoff. This AD requires performing initial and repetitive angled ultrasonic inspections (AUSI) of certain HPC 7th-stage axial rotors for cracks and replacing the HPC 7th-stage axial rotors if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This AD was prompted by two engine fan blade-out (FBO) events that resulted in the separation of engine inlet cowl and fan cowl parts from the airplane. In one event, fan cowl parts damaged the fuselage, which caused loss of pressurization and subsequent emergency descent. This AD requires replacing the fasteners on the fan cowl support beam hinge fittings for certain airplanes and, for all airplanes, requires modifying the radial restraint assembly and installing an external doubler at the starter vent, or as an option, installing a serviceable fan cowl. This AD also requires revising the existing maintenance or inspection program, as applicable, to incorporate new airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.
