Airworthiness Directive · Amendment 39-18195 · Ice and rain protection
Dassault Aviation Airplanes
This AD applies to all Dassault Aviation Model FALCON 2000EX airplanes, certificated in any category.
We are adopting a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 2000EX airplanes. This AD requires revising the airplane flight manual to include a procedure for addressing minimum fan speed rotation (N1) values during stand-alone engine anti-ice system operation for engines equipped with certain air inlets. This AD was prompted by a quality review of recently delivered airplanes which identified a manufacturing deficiency of some engine air inlet anti-ice piccolo tubes. We are issuing this AD to detect and correct reduced performance of the engine anti-ice protection system, leading to ice accretion and ingestion into the engines, which could result in dual engine power loss and consequent reduced controllability of the airplane.
(1) Within 10 flight cycles after the effective date of this AD: Revise the Limitations Section of the Dassault Falcon 2000EX AFM to include the statement in figure 1 to this paragraph. This may be done by inserting a copy of this AD in the AFM. When a statement identical to that in figure 1 to this paragraph has been included in the general revisions of the AFM, the general revisions may be inserted into the AFM, and the copy of this AD may be removed from the AFM.
(2) Airplanes on which the air engine inlet on both engines has a mark “NRK” on the associated data plate are not affected by the requirements in paragraph (g)(1) of this AD.
Note 1 to paragraph (g)(2) of this AD: Engine air inlets which have been refurbished and comply with the design standard are marked as “NRK” on the air inlet data plate.
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.
