Airworthiness Directive · Amendment 39-23183 · Navigation
Dassault Aviation Airplanes
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.
The FAA is superseding Airworthiness Directive (AD) 2022-12- 10, which applied to certain Dassault Aviation Model FALCON 7X airplanes. AD 2022-12-10 required revising the existing airplane flight manual (AFM) to provide emergency procedures for inconsistent or unreliable flight data, emergency and abnormal operations procedures for the generic input/output (GEN I/O) internal module failure, and emergency procedures for additional information. AD 2022-12-10 also required revising the existing minimum equipment list (MEL) for the multi-function probe heating, air data, and inertial reference systems. Since the FAA issued AD 2022-12-10, the manufacturer developed modifications that fix a weak point in the avionics architecture. This AD continues to require the actions in AD 2022-12-10 and removes certain airplanes from the applicability. This AD also requires modification of the avionics system and related revisions to the existing AFM and MEL. The FAA is issuing this AD to address the unsafe condition on these products.
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.
(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.
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.
Although the material referenced in EASA AD 2023-0003R1 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
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 manager of the International Validation Branch, send it to the attention of the person identified in paragraph (l) of this AD and email to: AMOC@faa.gov. 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 Dassault Aviation's EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature.
