ACTION: Final rule. SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2021-21-02, which applied 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 2021-21-02 required replacing certain parts manufacturer approval (PMA) Ni-Cd batteries with serviceable Ni-Cd batteries or maintaining the electrical storage capacity of those PMA Ni-Cd batteries during airplane storage or parking. This AD was prompted by a determination that the on-wing preservation procedures originally provided in that AD did not ensure the expected preservation of the battery capacity. This AD adds airplanes to the applicability and requires replacing each affected part with a serviceable part before release to service of an airplane after a storage or parking period, as applicable. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective July 3, 2024. ADDRESSES: AD Docket: You may examine the AD docket at regulations.gov under Docket No. FAA-2024-0221; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this final rule, any comments received, and other information. The address for Docket Operations is U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE, Washington, DC 20590.

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2021-21-02, Amendment 39-21762 (86 FR 62898, November 15, 2021) (AD 2021-21-02). AD 2021-21-02 applied 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. The NPRM published in the Federal Register on February 9, 2024 (89 FR 9074). The NPRM was prompted by a determination that the on-wing preservation procedures originally provided in that AD did not ensure the expected preservation of the battery capacity. In the NPRM, the FAA proposed to add Model A300 series airplanes; Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes); Model A310 series airplanes; and Model A350-941 and -1041 airplanes to the applicability. The FAA proposed that the superseding AD would retain none of the requirements of AD 2021-21-02. The FAA proposed to require replacing each affected part with a serviceable part before release to service of an airplane after a storage or parking period, as applicable. The FAA is issuing this AD to address reduced battery endurance performance, which could possibly result in failure to supply the minimum essential electrical power …
