Models named: FALCON 900EX, 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 900EX and FALCON 2000EX airplanes, certificated in any category.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
At the later of the applicable times specified in paragraphs (g)(1) and (g)(2) of this AD: Replace each affected aileron servo actuator, as identified in figure 1 to paragraph (g) of this AD (for Model FALCON 900EX airplanes) or figure 2 to paragraph (g) of this AD (for Model FALCON 2000EX airplanes), with a serviceable part in accordance with the Accomplishment Instructions of Dassault Service Bulletin F900EX-476, Revision 1, dated June 25, 2014; or Dassault Service Bulletin F2000EX-350, dated April 9, 2014; except where Dassault Service Bulletin F900EX-476, Revision 1, dated June 25, 2014; or F2000EX-350, dated April 9, 2014; specify to “remove” the applicable aileron servo actuator, this AD requires replacement of the applicable aileron servo actuator. A serviceable part is one that is specified in the “New P/N” column in the table of paragraph 3., “Material Information,” of Dassault Service Bulletin F900EX-476, Revision 1, dated June 25, 2014; or Dassault Service Bulletin F2000EX-350, dated April 9, 2014. (1) For airplanes on which the aileron servo actuator was not replaced during maintenance: At the later of the times specified in paragraphs (g)(1)(i) and (g)(1)(ii) of this AD. (i) Within 25 months or 1,640 flight hours, whichever occurs first, since the date of issuance of the original airworthiness certificate or date of issuance for the original export certificate of airworthiness. (ii) Within 30 days after the effective date of this AD. (2) For airplanes on which the aileron servo actuator was replaced during maintenance: At the later of the times specified in paragraphs (g)(2)(i) and (g)(2)(ii) of this AD. (i) Within 1,640 flight hours after replacement of the aileron servo actuator during maintenance. (ii) Within 30 days after the effective date of this AD. Note 1 to paragraph (g) of this AD: The affected aileron servo actuators are known to be installed before airplane delivery on Model FALCON 900EX airplanes having serial numbers (S/Ns) 265 through 270 inclusive, S/N 272 and S/N 273; Model FALCON 2000EX airplanes having S/N 243, S/Ns 246 through 258 inclusive, S/Ns 260 through 263 inclusive, S/Ns 702 through 710 inclusive and S/N 714; and during a maintenance operation on Model FALCON 900EX airplane having S/N 177, after airplane delivery.

Unsafe condition
This AD was prompted by a review that identified a nonconformity between the torque value applied to the screw-nuts of aileron servo actuators, and the torque value specified by the type design. We are issuing this AD to prevent desynchronization between two servo actuator barrels, which could lead to reduced control of the airplane during roll maneuvers at low altitude.
Affected ADs
None.

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.
