Airworthiness Directive · Amendment 39-22717 · Time limits/maintenance checks
Airbus SAS Airplanes
This AD applies to Airbus SAS Model A350-941 and -1041 airplanes, certificated in any category, with an original airworthiness certificate or original export certificate of airworthiness issued on or before June 1, 2023.
The FAA is superseding Airworthiness Directive (AD) 2021-24- 20, which applied to all Airbus SAS Model A350-941 and -1041 airplanes, and AD 2023-03-05, which applied to certain Airbus SAS Model A350-941 and -1041 airplanes. AD 2021-24-20 required repetitive water drainage and plug cleaning of the left- and right-hand slat geared rotary actuators (SGRAs) having a certain part number installed on slat 5 track 12 with certain functional item numbers. AD 2023-03-05 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD continues to require certain actions in AD 2021-24-20 and AD 2023-03-05 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.
This paragraph restates the requirements of paragraph (g) of AD 2021-24-20, with no changes. Except as specified in paragraph (h) of this AD, comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2021-0130R1, dated June 10, 2021 (EASA AD 2021-0130R1). Accomplishing the revision of the existing maintenance or inspection program required by paragraph (m) of this AD terminates the requirements of this paragraph.
This paragraph restates the exceptions specified in paragraph (h) of AD 2021-24-20, with no changes.
(1) Where EASA AD 2021-0130R1 refers to “the effective date of the original issue of this [EASA] AD,” this AD requires using January 27, 2022 (the effective date of AD 2021-24-20).
(2) The “Remarks” section of EASA AD 2021-0130R1 does not apply to this AD.
This paragraph restates the no reporting requirement of paragraph (i) of AD 2021-24-20, with no changes. Although the service information referenced in EASA AD 2021-0130R1 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
This paragraph restates the requirements of paragraph (j) of AD 2023-03-05, with no changes. For airplanes with an original airworthiness certificate or original export certificate of airworthiness issued on or before May 2, 2022: Except as specified in paragraph (k) of this AD, comply with all required actions and compliance times specified in, and in accordance with, EASA AD 2022-0127, dated June 28, 2022 (EASA AD 2022-0127).

(3) The initial compliance time for doing the tasks specified in paragraph (3) of EASA AD 2022-0127 is at the applicable “limitations” as incorporated by the requirements of paragraph (3) of EASA AD 2022-0127, or within 90 days after March 23, 2023 (the effective date of AD 2023-03-05), whichever occurs later.
