2023-20-02: Engine Fuel and Control

1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. 2. The FAA amends § 39.13 by: a. Removing Airworthiness Directive (AD) 2022-18-12, Amendment 39-22163 (87 FR 56561, September 15, 2022); and b. Adding the following new AD: 2023-20-02 Airbus SAS: Amendment 39-22561; Docket No. FAA-2023-1213; Project Identifier MCAI-2022-01615-T. (a) Effective Date This airworthiness directive (AD) is effective November 9, 2023. (b) Affected ADs This AD replaces AD 2022-18-12, Amendment 39-22163 (87 FR 56561, September 15, 2022) (AD 2022-18-12). (c) Applicability This AD applies to all Airbus SAS Model A330-841 and -941 airplanes, certificated in any category. (d) Subject Air Transport Association (ATA) of America Code 73, Engine Fuel and Control. (e) 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. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Requirements 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). (h) Exceptions to EASA AD 2022-0253 (1) Where EASA AD 2022-0253 refers to its effective date, this AD requires using the effective date of this AD. (2) Where EASA AD 2022-0253 refers to "10 September 2021," this AD requires using October 20, 2022 (the effective date of AD 2022-18-12). (3) Where EASA AD 2022-0253 refers to "10 September 2023," this AD requires using October 20, 2024 (24 months after October 20, 2022, the effective date of AD 2022-18-12). (4) This AD does not adopt the "Remarks" section of EASA AD 2022-0253. (i) Additional AD Provisions The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, International Validation Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or responsible Flight Standards Office, as appropriate. If sending information directly to the International Validation Branch, send it to the attention of the person identified in paragraph (j) of this AD. Information may be emailed to: [email protected]. Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the responsible Flight Standards Office. (2) Contacting the Manufacturer: For any requirement in this AD to obtain instructions from a manufacturer, the instructions must be accomplished using a method approved by the Manager, International Validation Branch, FAA; or EASA; or Airbus SAS's EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature. (3) Required for Compliance (RC): Except as required by paragraph (i)(2) of this AD, if any service information contains procedures or tests that are identified as RC, those procedures and tests must be done to comply with this AD; any procedures or tests that are not identified as RC are recommended. Those procedures and tests that are not identified as RC may be deviated from using accepted methods in accordance with the operator's maintenance or inspection program without obtaining approval of an AMOC, provided the procedures and tests identified as RC can be done and the airplane can be put back in an airworthy condition. Any substitutions or changes to procedures or tests identified as RC require approval of an AMOC.
