AD 2017-25-11 Airworthiness Directives; Dassault Aviation Airplanes
Models named: FALCON 2000EX. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to all Dassault Aviation Model FALCON 2000EX airplanes, certificated in any category.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
For airplanes other than those on which an engine air inlet having part number (P/N) 06ND71600-1, with a marking “NTR-RKFAL97” “NTR-RKFAL98,” “F2000EX-384,” or “F2000EX-384-R1” on the air inlet data plate has been incorporated on both engines: Within 1,300 flight hours or 26 months after the effective date of this AD, whichever occurs first; inspect each anti-ice “piccolo” tube assembly of each engine air inlet for discrepancies ( i.e., an incorrect opening diameter of the anti-ice tube assembly or perforation holes blocked by residue), and do all applicable corrective actions, in accordance with the Accomplishment Instructions of Dassault Falcon 2000EX Service Bulletin F2000EX-384, Revision 1, dated March 1, 2016; except as required by paragraph (h) of this AD. Do all applicable corrective actions before further flight.
Unsafe condition
This AD was prompted by a quality review of certain delivered airplanes, which identified a manufacturing deficiency of certain engine air inlet anti-ice “piccolo” tubes. We are issuing this AD to detect and correct discrepancies of each anti-ice “piccolo” tube assembly of certain engine air inlets; this condition could result in reduced performance of the engine anti-ice protection system, leading to ice accretion and ingestion into the engines, and possibly resulting in dual engine power loss and consequent reduced controllability of the airplane.
Affected ADs
This AD affects AD 2015-13-08, Amendment 39-18195 (80 FR 37150, June 30, 2015) (“AD 2015-13-08”).

You just looked this one up by hand
TrackAD holds all 12,278 of them and matches them against the aircraft you actually look after — airframe, engine, propeller and appliances in one pass — then works out what falls due and when.
- Bring your existing list in from a spreadsheet Paste the rows straight out of Excel. Headers like C/W Date and N/A are read for you.
- A copy that works when this does not One file. No internet, no login, no this software running. For the morning something has to be produced and the computer is not cooperating.
- $5 a month, or $50 a year Up to 50 aircraft on either.
