Airworthiness Directive · Amendment 39-21172 · Flight controls
Airbus SAS Airplanes
Superseded. A later AD replaced this one: AD 2024-08-05. Comply with the one in force.
This AD applies to all Airbus SAS Model A330-941 airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-941 airplanes. This AD was prompted by a report that seven spoiler servo-controls (SSCs) lost hydraulic locking function due to a sheared seal on the blocking valve. This AD requires repetitive operational tests of the hydraulic locking function on each SSC and replacement if necessary, as specified in a European Union Aviation Safety Agency (EASA), 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 2020-0054, dated March 11, 2020 (“EASA AD 2020-0054”).
The “Remarks” section of EASA AD 2020-0054 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.
