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 adding the following new airworthiness directive: 2021-22-25 Airbus SAS: Amendment 39-21798; Docket No. FAA-2021-0568; Project Identifier MCAI-2021-00446-T. (a) Effective Date This airworthiness directive (AD) is effective January 5, 2022. (b) Affected ADs None. (c) Applicability This AD applies to all Airbus SAS airplanes specified in paragraphs (c)(1) through (8) of this AD, certificated in any category. (1) Model A330-201, -202, -203, -223, and -243 airplanes. (2) Model A330-223F and -243F airplanes. (3) Model A330-301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes. (4) Model A330-941 airplanes. (5) Model A340-211, -212, and -213 airplanes. (6) Model A340-311, -312, and -313 airplanes. (7) Model A340-541 airplanes. (8) Model A340-642 airplanes. (d) Subject Air Transport Association (ATA) of America Code 34, Navigation. (e) Reason This AD was prompted by a report that during the frame of flight test clearance process, a detailed analysis of air data reference (ADR) failure scenarios led to the identification that compliance requirements for loads and handling qualities throughout the flight envelope could be impaired in case of dispatch with one ADR inoperative (master minimum equipment list (MMEL) item 34-10-01) during the maximum interval allowed by the current MMEL. The FAA is issuing this AD to address the possibility of in-flight loss of a second ADR combined with erroneous low speed data provided by the remaining functional ADR, which could result in loss of 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 2021-0103, dated April 13, 2021 (EASA AD 2021-0103). (h) Exceptions to EASA AD 2021-0103 (1) Where EASA AD 2021-0103 refers to its effective date, this AD requires using the effective date of this AD. (2) Where EASA AD 2021-0103 specifies to implement certain information in "the MMEL MER" into the "operational documentation," this AD requires revising the operator's existing FAA-approved minimum equipment list (MEL) to incorporate that information. (3) Where EASA AD 2021-0103 specifies to "inform all flight crews, and, thereafter, operate the aeroplane accordingly," this AD does not require those actions as those actions are already required by existing FAA operating regulations. (4) The "Remarks" section of EASA AD 2021-0103 does not apply to this AD. (i) Additional AD Provisions The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Large Aircraft Section, 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 Large Aircraft Section, 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, Large Aircraft Section, 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.
