Additionally, the EPA is proposing to approve portions of the 2009 Texas Regional Haze SIP submission and portions of the 2010 Oklahoma Regional Haze SIP submission that relate to reasonable progress requirements for the first planning period from 2007 through 2018. Finally, the EPA is also withdrawing its 2023 proposed disapprovals regarding Texas's and Oklahoma's first planning period SIPs and its 2024 proposed action regarding Texas's second planning period SIP. The EPA is taking this action pursuant to sections 110 and 169A of the Act.

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 is superseding Airworthiness Directive (AD) 2023-10- 08, which applied to all ATR--GIE Avions de Transport R[eacute]gional Model ATR42-200, -300, and -320 airplanes. AD 2023-10-08 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2023-10-08, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This AD continues to require certain actions in AD 2023-10-08 and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as 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 certain Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as 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.
Learn More🚁Proposed Airworthiness Directives for Airbus Helicopters by FAA
The FAA proposes to supersede Airworthiness Directive (AD) 2019-19-13, which applies to certain Airbus Helicopters Model EC225LP helicopters. AD 2019-19-13 requires determining the total hours time- in-service (TIS) of the free wheel shafts of certain main rotor gearboxes (MGBs), replacing the MGB or right-hand side (RH) free wheel shaft, installing placard(s), and revising the Rotorcraft Flight Manual (RFM) for the helicopter. Since the FAA issued AD 2019-19-13, an additional part-numbered MGB has been identified to have the same unsafe condition and the FAA determined that additional changes are necessary. This proposed AD would require the actions of AD 2019-19-13 and, expand the applicability by adding the additional part-numbered MGB, change the requirement to determine the total hours TIS of a certain free wheel shaft, require repetitive replacement of the MGB or the RH free wheel shaft, change the requirements for who can replace parts, and expand the parts installation limitation conditions. 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 Airbus SAS Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -252N, -253N, -271N, -272N, -251NX, -252NX, -253NX, -271NX, and -272NX airplanes. This AD was prompted by the identification of an erroneous value of the main landing gear (MLG) tire width in the aircraft data files used for aircraft performance computation. This AD requires revising the existing airplane flight manual (AFM) to incorporate a complementary performance data file (CPDF) update as 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.
