Airworthiness Directive · Amendment 39-18615 · Ice and rain protection
Dassault Aviation Airplanes
Superseded. A later AD replaced this one: AD 2017-19-17. Comply with the one in force.
This AD applies to the Dassault Aviation airplanes identified in paragraphs (c)(1) and (c)(2) of this AD, certificated in any category.
(1) Model FALCON 900EX airplanes, serial numbers (S/Ns) 270 through 291 inclusive and 294.
(2) Model FALCON 2000EX airplanes, S/Ns 263 through 305 inclusive, 307 through 313 inclusive, 315, 320, and 701 through 734 inclusive.
We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 900EX and FALCON 2000EX airplanes. This AD requires revising the airplane flight manual (AFM) to include procedures to follow when an airplane is operating in icing conditions. This AD also provides optional terminating action for the AFM revision. This AD was prompted by a design review of in-production airplanes that identified a deficiency in certain wing anti-ice system ducting. A deficiency in the wing anti-ice system ducting could lead to undetected, reduced performance of the wing anti-ice system, with potential ice accretion and ingestion, possibly resulting in degraded engine power and degraded handling characteristics of the airplane. We are issuing this AD to ensure the flight crew has procedures for operating an airplane in icing conditions.
(1) For Model FALCON 900EX airplanes on which the actions specified in Dassault Service Bulletin F900EX-464 have not been accomplished: Within 10 flight cycles after the effective date of this AD, revise Section 4-200-05A, “OPERATION IN ICING CONDITIONS,” of the Model FALCON 900EX AFM to include the information in figure 1 to paragraph (g)(1) of this AD, and thereafter operate the airplane accordingly. The AFM revision may be done by inserting a copy of this AD into the AFM.
(2) For Model FALCON 2000EX airplanes on which the actions specified in Dassault Service Bulletin F2000EX-393 have not been accomplished: Within 10 flight cycles after the effective date of this AD, revise Section 4-200-05A, “OPERATION IN ICING CONDITIONS,” of the Model FALCON 2000EX AFM to include the information in figure 2 to paragraph (g)(2) of this AD, and thereafter operate the airplane accordingly. The AFM revision may be done by inserting a copy of this AD into the AFM.
A detailed inspection of the wing anti-ice system ducting for the presence of a diaphragm and, as applicable, a check of the part number, and re-identification of the wing anti-ice system ducting or replacement of the wing anti-ice system ducting, in accordance with the Accomplishment Instructions of Dassault Service Bulletin F900EX-464, dated June 20, 2016; or Service Bulletin F2000EX-393, dated June 20, 2016; as applicable; terminates the requirements of paragraph (g) of this AD for that airplane only. After the applicable actions in the service information have been completed, the AFM revision required by paragraph (g) of this AD may be removed from the AFM for that airplane.
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.
