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) 2022-12-10, Amendment 39-22082 (87 FR 45246, July 28, 2022); and b. Adding the following new AD: 2025-22-05 Dassault Aviation: Amendment 39-23183; Docket No. FAA-2025-1729; Project Identifier MCAI-2024-00568-T. (a) Effective Date This airworthiness directive (AD) is effective January 2, 2026. (b) Affected ADs This AD replaces AD 2022-12-10, Amendment 39-22082 (87 FR 45246, July 28, 2022) (AD 2022-12-10). (c) Applicability This AD applies to Dassault Aviation Model FALCON 7X airplanes, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2023-0003R1, dated September 26, 2024 (EASA AD 2023-0003R1). Note 1 to paragraph (c): Model FALCON 7X airplanes with Dassault modification M1000 incorporated are commonly referred to as "Model FALCON 8X" as a marketing designation. (d) Subject Air Transport Association (ATA) of America Code 34, Navigation. (e) Unsafe Condition This AD was prompted by a report of a weak point identified in the Falcon 7X "EASy" avionics architecture, which, coupled with theoretical generic input/output (I/O) card failure, could lead to misleading data on display units and by development of modifications that fix that weak point in the avionics architecture. The FAA is issuing this AD to address misleading data on display units. The unsafe condition, if not addressed, could reduce safety margins and lead to increased pilot workload, possibly resulting in reduced controllability of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Requirements Except as specified in paragraphs (h) and (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, EASA AD 2023-0003R1. (h) Exceptions to EASA AD 2023-0003R1 (1) Where EASA AD 2023-0003R1 refers to September 6, 2021 (the effective of EASA AD 2021-0197), this AD requires using September 1, 2022 (the effective date of AD 2022-12-10). (2) Where EASA AD 2023-0003R1 refers to July 26, 2022 (the effective date of EASA AD 2022-0145, dated July 12, 2022), and January 20, 2023 (the effective date of EASA AD 2023-0003, dated January 6, 2023), this AD requires using the effective date of this AD. (3) Where paragraph (1) of EASA AD 2023-0003R1 requires operators to "inform all flight crews, and, thereafter, ensure that each pilot has performed the training and operates the aeroplane accordingly," and paragraph (2.2) of EASA AD 2023-0003R1 requires operators 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 (see 14 CFR 91.9, 91.505, 121.137, and 121.628(a)(2) and (5)). (4) Where paragraph (1.3) of EASA AD 2023-0003R1 specifies to "Implement the instructions of the MMEL-CP", this AD requires replacing that text with "Revise the operator's existing FAA-approved minimum equipment list (MEL) to incorporate that information ("the MMEL-CP" as specified in EASA AD 2023-0003R1)". (5) Paragraph (1.4) of EASA AD 2023-0003R1 does not apply to this AD. (6) This AD does not adopt the "Remarks" section of EASA AD 2023-0003R1. (i) Airplane Flight Manual (AFM) Revision Within 2 months after September 1, 2022 (the effective date of AD 2022-12-10), revise the applicable existing AFM to incorporate the information specified in figure 1 to paragraph (i) of this AD after sub-sub-section 2-200-70, Emergency Procedures, ADS with IRS miscompare, of sub-section 2-200, Emergency Procedures, of Section 2-Emergency Procedures.
