Airworthiness Directive · Amendment 39-21895 · Time limits/maintenance checks
Airbus SAS Airplanes
Superseded. A later AD replaced this one: AD 2024-01-05. Comply with the one in force.
This AD applies 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 30, 2021.
The FAA is superseding Airworthiness Directive (AD) 2021-11- 23, which applied to certain Airbus SAS Model A350-941 and -1041 airplanes. AD 2021-11-23 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, and, for certain airplanes, updating the hydraulic monitoring system to include additional redundancy. Since the FAA issued AD 2021-11-23, the FAA has determined 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. This AD also revises the applicability to include different airplanes. The FAA is issuing this AD to address the unsafe condition on these products.
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 2021-0209, dated September 15, 2021 (EASA AD 2021-0209).
(1) The requirements specified in paragraphs (1) and (2) of EASA AD 2021-0209 do not apply to this AD.
(2) Paragraph (3) of EASA AD 2021-0209 specifies revising “the AMP [aircraft maintenance program]” within 12 months after its effective date, but this AD requires revising the existing maintenance or inspection program, as applicable, to incorporate the “limitations, tasks and associated thresholds and intervals” specified in paragraph (3) of EASA AD 2021-0209 within 90 days after the effective date of this AD.
(3) The initial compliance time for doing the tasks specified in paragraph (3) of EASA AD 2021-0209 is at the applicable “associated thresholds” specified in paragraph (3) of EASA AD 2021-0209, or within 90 days after the effective date of this AD, whichever occurs later.
(4) The provisions specified in paragraphs (4) and (5) of EASA AD 2021-0209 do not apply to this AD.
(5) The “Remarks” section of EASA AD 2021-0209 does not apply to this AD.
After the maintenance or inspection program has been revised as required by paragraph (g) of this AD, no alternative actions (e.g., inspections), intervals, and critical design configuration control limitations (CDCCLs) are allowed unless they are approved as specified in the provisions of the “Ref. Publications” section of EASA AD 2021-0209.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
