Airworthiness Directive · Amendment 39-18376 · 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Superseded.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 all DASSAULT AVIATION Model MYSTERE-FALCON 900 airplanes, certificated in any category.
We are superseding Airworthiness Directive (AD) 2002-23-20, for certain Dassault Aviation Model FALCON 900EX and MYSTERE-FALCON 900 airplanes. AD 2002-23-20 required repetitive operational tests of the flap asymmetry detection system to verify proper functioning, and repair if necessary; repetitive replacement of the inboard flap jackscrews with new or reconditioned jackscrews; and repetitive measurement of the screw/nut play of the jackscrews on the inboard and outboard flaps to detect discrepancies, and corrective action if necessary. AD 2002-23-20 also required a revision of the airplane flight manual. Since we issued AD 2002-23-20, the maintenance manual has been revised. This AD requires revising the maintenance or inspection program, as applicable, to include the maintenance tasks and airworthiness limitations specified in the Airworthiness Limitations section of the airplane maintenance manual. This AD also removes the Model FALCON 900EX airplanes from the applicability. We are issuing this AD to prevent reduced structural integrity of the airplane.
Within 30 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 20, dated October 2012, of the Dassault Aviation Falcon 900 Maintenance Manual. The initial compliance time for accomplishing the actions specified in Chapter 5-40, Airworthiness Limitations, Revision 20, dated October 2012, of the Dassault Aviation Falcon 900 Maintenance Manual, is within the applicable times specified in the maintenance manual or within 30 days after the effective date of this AD, whichever occurs later, except as provided by paragraphs (g)(1) through (g)(4) of this AD.
(1) The term “LDG” in the “First Inspection” column of any table in the service information means total airplane landings.
(2) The term “FH” in the “First Inspection” column of any table in the service information means total flight hours.
(3) The term “FC” in the “First Inspection” column of any table in the service information means total flight cycles.
(4) The term “M” in the “First Inspection” column of any table in the service information means months.
Accomplishing paragraph (g) of this AD terminates the requirements of paragraph (g)(1) of AD 2010-26-05, Amendment 39-16544 (75 FR 79952, December 21, 2010), for DASSAULT AVIATION Model MYSTERE-FALCON 900 airplanes.
After accomplishing the revision 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.
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.
