Airworthiness Directive · Amendment 39-22548 · Time limits/maintenance checks
Dassault Aviation Airplanes
This AD applies to Dassault Aviation Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2023-0058, dated March 16, 2023 (EASA AD 2023-0058).
The FAA is superseding Airworthiness Directive (AD) 2020-03- 19, which applied to certain Dassault Aviation Model MYSTERE-FALCON 20- C5, 20-D5, 20-E5, and 20-F5 airplanes. AD 2020-03-19 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD continues to require the actions in AD 2020-03-19 and requires revising the existing maintenance or inspection program, as applicable, to incorporate additional new or more restrictive airworthiness limitations; as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The FAA is issuing this AD to address the unsafe condition on these products.
This paragraph restates the requirements of paragraph (g) of AD 2020-03-19, with a new terminating action. Within 90 days after April 2, 2020 (the effective date of AD 2020-03-19), revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in Chapter 5-40-00, Airworthiness Limitations, of the Dassault Falcon 20 Retrofit 731 Maintenance Manual, Revision 13, dated January 1, 2019. The initial compliance time for doing the tasks is at the time specified in Chapter 5-40-00, Airworthiness Limitations, of the Dassault Falcon 20 Retrofit 731 Maintenance Manual, Revision 13, dated January 1, 2019, or within 90 days after April 2, 2020, whichever occurs later. Accomplishing the revision of the existing maintenance or inspection program required by paragraph (i) of this AD terminates the requirements of this paragraph.
This paragraph restates the requirements of paragraph (h) of AD 2020-03-19, with a new exception. Except as required by paragraph (i) of this AD, after the existing maintenance or inspection program has been revised as required by paragraph (g) of this AD, no alternative actions (e.g., inspections) or intervals are allowed unless the actions or intervals are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (m)(1) of this AD.
Except as specified in paragraph (j) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, EASA AD 2023-0058. Accomplishing the revision of the existing maintenance or inspection program required by this paragraph terminates the requirements of paragraph (g) of this AD.
(1) This AD does not adopt the requirements specified in paragraphs (1) and (2) of EASA AD 2023-0058.
(2) Paragraph (3) of EASA AD 2023-0058 specifies revising “the approved AMP” within 12 months after its effective date, but this AD requires revising the existing maintenance or inspection program, as applicable, within 90 days after the effective date of this AD.
(3) The initial compliance time for doing the tasks specified in paragraph (3) of EASA AD 2023-0058 is at the applicable “limitations” as incorporated by the requirements of paragraph (3) of EASA AD 2023-0058, or within 90 days after the effective date of this AD, whichever occurs later.
(4) This AD does not adopt the provisions specified in paragraphs (4) and (5) of EASA AD 2023-0058.
(5) This AD does not adopt the “Remarks” section of EASA AD 2023-0058.
After the existing maintenance or inspection program has been revised as required by paragraph (i) of this AD, no alternative actions (e.g., inspections) and intervals are allowed unless they are approved as specified in the provisions of the “Ref. Publications” section of EASA AD 2023-0058.
Accomplishing the actions required by paragraph (g) or (i) of this AD terminates all requirements of paragraph (g)(1) of AD 2010-26-05 for Dassault Aviation Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes, except those on which the Dassault Aviation MYSTERE-FALCON 20 Supplemental Structural Inspection Program has been embodied, only.
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 International Validation Branch, send it to the attention of the person identified in paragraph (n) 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.
