Airworthiness Directive · Amendment 39-21328 · Flight controls
Airbus SAS Airplanes
This AD applies to all Airbus SAS Model A350-1041 airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A350-1041 airplanes. This AD was prompted by a report that, during testing, wear was found on the drive strut anti-rotation knuckles and lever bearing assembly (LBA) bushes on a certain flap station. This AD requires repetitive inspections for wear or corrosion damage of the drive strut anti-rotation knuckles and LBA bushes, and applicable corrective actions, 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.
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 2020-0126, dated June 3, 2020 (“EASA AD 2020-0126”).
(1) Where EASA AD 2020-0126 refers to its effective date, this AD requires using the effective date of this AD.
(2) The “Remarks” section of EASA AD 2020-0126 does not apply to this AD.
(3) Paragraph (4) of EASA AD 2020-0126 specifies to report inspection results to Airbus within a certain compliance time. For this AD, report inspection results at the applicable time specified in paragraph (h)(3)(i) or (ii) of this AD.
(i) If the inspection was done on or after the effective date of this AD: Submit the report within 90 days after the inspection.
(ii) If the inspection was done before the effective date of this AD: Submit the report within 90 days after the effective date of this AD.
