Federal Aviation Administration January 22, 2024 – Federal Register Recent Federal Regulation Documents

The FAA proposes to supersede Airworthiness Directive (AD) 2021-20-08, which applies to certain Airbus SAS Model A318, A319, A320, A321, A330-200, A330-200 Freighter, A330-300, A330-800, A330-900, A340- 200, A340-300, A340-500, A340-600, and A380-800 series airplanes. AD 2021-20-08 requires replacing certain parts manufacturer approval (PMA) nickel-cadmium (Ni-Cd) batteries with serviceable Ni-Cd batteries. Since the FAA issued AD 2021-20-08, it was determined that the on-wing preservation procedures originally provided in the service information did not ensure the expected preservation of the battery capacity. This proposed AD would add airplanes to the applicability and require replacement of certain affected parts with serviceable parts as a precondition for return to service of airplanes from storage or parking, 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.

This action establishes United States Area Navigation (RNAV) Route Q-476, and amends RNAV Route T-393 in support of the Next Generation Air Transportation System (NextGen) efforts to provide a modern RNAV route structure to improve the safety and efficiency of the National Airspace System (NAS).

This action delays the effective date of a final rule published in the Federal Register on October 19, 2023, amending Very High Frequency Omnidirectional Range (VOR) Federal Airway V-36 and establishing Canadian Area Navigation (RNAV) Route T-675 in the northcentral United States (U.S.) airspace. The FAA is delaying the effective date to allow sufficient time for completion of the required flight inspection of the route.
