Airworthiness Directive · Amendment 39-23077 · Flight controls
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 hydraulic leakage from the spoiler power control unit (SPPCU) in service. Relevant investigations determined that, following certain failures, the spoiler electrical control unit (SPECU) can deliver an untimely and permanent activation command to the SPPCU standby electrical pump, which can possibly result in overheating and significant hydraulic leakage of the unit. This AD requires replacing the affected SPECUs and prohibits the installation of affected parts. 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 2024-0224, dated November 26, 2024 (EASA AD 2024-0224).
(1) Where EASA AD 2024-0224 refers to its effective date, this AD requires using the effective date of this AD.
(2) This AD does not adopt the “Remarks” section of EASA AD 2024-0224.
(3) Where EASA AD 2024-0224 defines a serviceable part as an “SPECU, eligible for installation in accordance with Dassault instructions, which is not an affected part”, this AD requires replacing that text with “SPECU, eligible for installation, which is not an affected part”.
Although the material referenced in EASA AD 2024-0224 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 (k) 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.
