Airworthiness Directive · Amendment 39-21602 · Powerplant
Airbus SAS Airplanes
This AD applies to all Airbus SAS Model A330-243, A330-243F, A330-341, A330-342, and A330-343 airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-243, A330-243F, A330-341, A330-342, and A330-343 airplanes. This AD was prompted by a report of an in-flight turnback due to loss of green and blue hydraulic systems in cruise. This AD requires inspecting for discrepancies of the hydraulic pressure switch harnesses of affected engines, 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 2021-0128, dated May 17, 2021 (EASA AD 2021-0128).
(1) Where EASA AD 2021-0128 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where paragraph (2) of EASA AD 2021-0128 specifies actions if “discrepancies are found,” for this AD “discrepancies” include incorrect harness routing and pump pressure connections.
(3) The “Remarks” section of EASA AD 2021-0128 does not apply to this AD.
Although the service information referenced in EASA AD 2021-0128 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
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.
