Airworthiness Directive · Amendment 39-19799 · Time limits/maintenance checks
Dassault Aviation Airplanes
Superseded. A later AD replaced this one: AD 2020-26-07. 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 Directives (ADs) 2016-01- 16, 2017-19-03, and 2018-19-05, which applied to Dassault Aviation Model MYSTERE-FALCON 900 airplanes. Those ADs require revising the maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance requirements and/or airworthiness limitations. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since AD 2018-19-05 was issued, the FAA has determined 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 2018-19-05, with no changes. Within 90 days after October 26, 2018 (the effective date of AD 2018-19-05), revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in Chapter 5-40, Airworthiness Limitations, Revision 23, dated September 2017, 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 23, dated September 2017, of the Dassault Aviation Falcon 900 Maintenance Manual, or within 90 days after October 26, 2018, 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.
This paragraph restates the requirements of paragraph (h) of AD 2018-19-05, 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 (l)(1) of this AD.
Within 90 days after the effective date of this AD, 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 the effective date of this AD, 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. Doing the revision required by this paragraph terminates the actions required by paragraph (g) of this AD.
After the existing maintenance or inspection program has been revised as required by paragraph (i) of this AD, no alternative actions (e.g., inspections) or intervals may be used unless the actions or intervals are approved as an AMOC in accordance with the procedures specified in paragraph (l)(1) of this AD.
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.
