Airworthiness Directive · Amendment 39-19047 · Ice and rain protection
Dassault Aviation Airplanes
Superseded. A later AD replaced this one: AD 2017-23-10. 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 superseding Airworthiness Directive (AD) 2016-17-02, which applied to certain Dassault Aviation Model FALCON 900EX and FALCON 2000EX airplanes. AD 2016-17-02 required revising the airplane flight manual (AFM) to include procedures to follow when an airplane is operating in icing conditions. AD 2016-17-02 also provided optional actions after which the AFM revision may be removed from the AFM. Since we issued AD 2016-17-02, we have determined additional actions are necessary to address the identified unsafe condition. This new AD retains the requirement of AD 2016-17-02, and also requires a detailed inspection of the wing anti-ice system ducting (anti-ice pipes) for the presence of a diaphragm, and replacement of ducting or re- identification of the ducting part marking. We are issuing this AD to address the unsafe condition on these products.
This paragraph restates the requirements of paragraph (g) of AD 2016-17-02, with no changes.
(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 September 6, 2016 (the effective date of AD 2016-17-02), 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 September 6, 2016 (the effective date of AD 2016-17-02), 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.
Within 9 months after the effective date of this AD: Do a detailed inspection of the wing anti-ice system ducting (anti-ice pipes) for the presence of a diaphragm, and do all applicable actions specified in paragraph (h)(1) or (h)(2) of this AD, 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. After the applicable actions specified in paragraph (h)(1) or (h)(2) of this AD have been completed, the AFM revision required by paragraph (g) of this AD may be removed from the AFM for that airplane.
(1) If during the inspection required by the introductory text to paragraph (h) of this AD it is determined that a diaphragm is present: Before further flight, replace the wing anti-ice system ducting.
(2) If during the inspection required by the introductory text to paragraph (h) of this AD it is determined that a diaphragm is not present: Before further flight, do a check of the anti-ice pipe part number and re-identify the wing anti-ice system ducting.
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.
