Airworthiness Directive · Amendment 39-19405 · Time limits/maintenance checks
Dassault Aviation Airplanes
Superseded. A later AD replaced this one: AD 2019-23-05. Comply with the one in force.
This AD applies to Dassault Aviation Model MYSTERE-FALCON 900 airplanes, all serial numbers, certificated in any category.
We are adopting a new airworthiness directive (AD) for all Dassault Aviation Model MYSTERE-FALCON 900 airplanes. This AD was prompted by a determination that more restrictive maintenance requirements and airworthiness limitations are necessary. This AD requires revising the maintenance or inspection program, as applicable, to incorporate new and more restrictive maintenance requirements and airworthiness limitations. We are issuing this AD to address the unsafe condition on these products.
Within 90 days after the effective date of this AD, revise the 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 time 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 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.
After the 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 (j)(1) of this AD.
(1) Accomplishing the actions required by paragraph (g) of this AD terminates all requirements of AD 2016-01-16 and AD 2017-19-03.
(2) Accomplishing the actions required by paragraph (g) 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.
