Airworthiness Directive · Amendment 39-22780 · Pneumatic
Dassault Aviation Airplanes
This AD applies to all Dassault Aviation Model FALCON 7X airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 7X airplanes. This AD was prompted by a determination that certain left-hand (LH) and right-hand (RH) pylon bleed air leak detectors (BALDs) might be defective, due to incorrect manufacturing processes and incomplete acceptance test procedures. This AD requires a one-time operational check of affected parts and, depending on findings, accomplishment of applicable corrective action, and limits the installation of affected parts under certain conditions, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
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 2023-0216, dated December 18, 2023 (EASA AD 2023-0216).
(1) Where EASA AD 2023-0216 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where the group definitions in EASA AD 2023-0216 specify “the SB,” this AD requires replacing that text with “Dassault Service Bulletin 7X-572, Erratum, dated October 24, 2023.”
(3) Where the service information referenced in EASA AD 2023-0216 refers to “suspicious traces,” this AD requires replacing that text with “burn marks or signs of overheating.”
(4) Where EASA AD 2023-0216 refers to “any discrepancy,” this AD requires replacing that text with “any routing interference, burn marks, signs of overheating, or any specified crew alerting system (CAS) message that does not show on a Primary Display Unit (PDU) during testing.”
(5) This AD does not adopt the “Remarks” section of EASA AD 2023-0216.
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, mail it to the address identified in paragraph (j) 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, 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.
