Airworthiness Directives; Airbus SAS Airplanes

FAA / Federal Register · 2024-11587

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.
