AD 2023-20-02 Airworthiness Directives; Airbus SAS Airplanes
Models named: A330-841, -941. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to all Airbus SAS Model A330-841 and -941 airplanes, certificated in any category.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
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 2022-0253, dated December 19, 2022 (EASA AD 2022-0253).
Unsafe condition
This AD was prompted by a determination that engine crystal icing protection could be (temporarily) lost if an erroneous total pressure value is provided by the airplane system and the engine electronic control (EEC) software used to correct the system requires modification. This modification may conflict with EEC software to address erroneous electronic centralized airplane monitoring (ECAM) engine oil pressure warnings. The FAA is issuing this AD to address erroneous total pressure values being provided by the airplane system and any EEC software that should not be intermixed. The unsafe condition, if not addressed, could result in dual engine in-flight shut-down, and subsequent reduced control of the airplane.
Affected ADs
This AD replaces AD 2022-18-12, Amendment 39-22163 (87 FR 56561, September 15, 2022) (AD 2022-18-12).
