Airworthiness Directive · Amendment 39-22082 · Navigation
Dassault Aviation Airplanes
Superseded. A later AD replaced this one: AD 2025-22-05. Comply with the one in force.
This AD applies to all Dassault Aviation Model FALCON 7X airplanes, certificated in any category, except airplanes having Dassault modification M2091 embodied in production.
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 adopting a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 7X airplanes. 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. This AD requires revising the existing airplane flight manual (AFM) to provide emergency procedures for inconsistent or unreliable flight data and emergency and abnormal operations procedures for the GEN I/O internal module failure, and revising the operator's existing FAA- approved minimum equipment list (MEL) items for the multi-function probe heating, air data, and inertial reference systems, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also requires revising the existing AFM to incorporate additional information in the emergency procedures. 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, European Union Aviation Safety Agency (EASA) AD 2021-0197, dated August 23, 2021 (EASA AD 2021-0197).
(1) Where EASA AD 2021-0197 refers to its effective date, this AD requires using the effective date of this AD.
(2) Whereas EASA AD 2021-0197 requires operators to “inform all flight crews, and, thereafter, ensure that each pilot has performed the training and operate the aeroplane accordingly,” this AD does not require those actions.
(3) Where paragraph (3) of EASA AD 2021-0197 specifies to “implement the instructions of the MMEL-CP,” this AD requires revising the operator's existing FAA-approved minimum equipment list (MEL) to incorporate that information (“the MMEL-CP” as specified in EASA AD 2021-0197).
(4) Paragraph (4) of EASA AD 2021-0197 does not apply to this AD.
(5) The “Remarks” section of EASA AD 2021-0197 does not apply to this AD.
Within 2 months after the effective date of this AD, 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.
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 (k) of this AD. Information may be emailed to: 9-AVS-AIR-730-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, Large Aircraft Section, 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.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
