Airworthiness Directive · Amendment 39-21362 · Time limits/maintenance checks
Dassault Aviation Airplanes
Superseded. A later AD replaced this one: AD 2023-04-10. Comply with the one in force.
This AD applies to all Dassault Aviation Model MYSTERE-FALCON 900 airplanes, certificated in any category.
The FAA is superseding Airworthiness Directive (AD) 2019-23- 05, which applied to all Dassault Aviation Model MYSTERE-FALCON 900 airplanes. AD 2019-23-05 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD continues to require revising the existing maintenance or inspection program, as applicable, to incorporate those new or more restrictive airworthiness limitations, and also 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 (i) of AD 2019-23-05, with no changes. Within 90 days after January 13, 2020 (the effective date of AD 2019-23-05), revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in Chapter 5-40, Airworthiness Limitations, Revision 24, dated September 2018, of the Dassault Aviation Falcon 900 Maintenance Manual. The initial compliance times for doing the tasks are at the times specified in Chapter 5-40, Airworthiness Limitations, Revision 24, dated September 2018, of the Dassault Aviation Falcon 900 Maintenance Manual, or within 90 days after January 13, 2020, whichever occurs later. The term “LDG” in the “First Inspection” column of any table in the service information specified in this paragraph means total airplane landings. The term “FH” in the “First Inspection” column of any table in the service information specified in this paragraph means total flight hours. The term “FC” in the “First Inspection” column of any table in the service information specified in this paragraph means total flight cycles. The term “M” in the “First Inspection” column of any table in the service information specified in this paragraph means months since the date of issuance of the original airworthiness certificate or the date of issuance of the original export certificate of airworthiness. Accomplishing the maintenance or inspection program revision required by paragraph (i) of this AD terminates the requirements of this paragraph.
This paragraph restates the requirements of paragraph (h) of AD 2019-23-05, 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 may be used 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, European Union Aviation Safety Agency (EASA) AD 2020-0115, dated May 20, 2020 (EASA AD 2020-0115). Accomplishing the maintenance or inspection program revision required by this paragraph terminates the requirements of paragraph (g) of this AD.
(1) The requirements specified in paragraphs (1) and (2) of EASA AD 2020-0115 do not apply to this AD.
(2) Paragraph (3) of EASA AD 2020-0115 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, to incorporate the “limitations, tasks and associated thresholds and intervals” specified in paragraph (3) of EASA AD 2020-0115 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 2020-0115 is at the applicable “associated thresholds” specified in paragraph (3) of EASA AD 2020-0115, or within 90 days after the effective date of this AD, whichever occurs later.
(4) The provisions specified in paragraphs (4) and (5) of EASA AD 2020-0115 do not apply to this AD.
(5) The “Remarks” section of EASA AD 2020-0115 does not apply to this AD.
After the maintenance or inspection program has been revised as required by paragraph (i) of this AD, no alternative actions (e.g., inspections) or intervals are allowed unless they are approved as specified in the provisions of the “Ref. Publications” section of EASA AD 2020-0115.
Accomplishing the actions required by paragraph (g) or (i) of this AD terminates the requirements of paragraph (g)(1) of AD 2010-26-05, for Dassault Aviation Model MYSTERE-FALCON 900 airplanes.
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.
