Airworthiness Directive · Amendment 39-19811 · Flight controls
Dassault Aviation Airplanes
This AD applies to Dassault Aviation Model FALCON 900EX and Model FALCON 2000EX airplanes, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2019-0273, dated November 4, 2019 (“EASA AD 2019-0273”).
The FAA is adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 900EX and Model FALCON 2000EX airplanes. This AD was prompted by reports of iced angle-of-attack (AoA) probes after take-off, with associated misleading airspeed indication and/or misleading stall warning. This AD requires revising the existing airplane flight manual (AFM) to provide the flightcrew with updated procedures related to manually activating heating of the AoA probes during line up, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, EASA AD 2019-0273.
(1) Where EASA AD 2019-0273 refers to its effective date, this AD requires using the effective date of this AD.
(2) The “Remarks” section of EASA AD 2019-0273 does not apply to 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.
