Airbus SAS Airplanes
Superseded. A later AD replaced this one: AD 2021-04-11. Comply with the one in force.
This AD applies to Airbus SAS Model A350-941 airplanes, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2019-0203, dated August 20, 2019 (“EASA AD 2019-0203”).
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 airplanes. This AD was prompted by a determination that ram air turbine (RAT) performance may be below the expected (certificated) level when the landing gear is extended. This AD requires installing flight control and guidance system (FCGS) software (SW) X11 Standard (STD), 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, EASA AD 2019-0203.
(1) Where EASA AD 2019-0203 refers to its effective date, this AD requires using the effective date of this AD.
(2) The “Remarks” section of EASA AD 2019-0203 does not apply to this AD.
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.
