Airworthiness Directive · Amendment 39-17466 · Electrical power
Dassault Aviation Airplanes
This AD applies to the airplanes specified in paragraphs (c)(1) and (c)(2) of this AD, certificated in any category.
(1) Dassault Aviation Model Mystere-Falcon 900 airplanes, serial numbers 142 and subsequent.
(2) Dassault Aviation Model Falcon 900EX airplanes, all serial numbers except those on which Dassault Aviation Modification M5741 has been embodied in production.
We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model Mystere-Falcon 900 and Falcon 900EX airplanes. This AD was prompted by reports of chafing between the tail strobe power supply and a hydraulic line. This AD requires modifying the tail strobe power supply wire routing. We are issuing this AD to prevent chafing between the tail strobe power supply and a hydraulic line, which could result in hydraulic fluid leakage and possible fire due to arcing, and consequent loss of control of the airplane due to structural failure of the tail.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 65 days or 200 flight hours after the effective date of this AD, whichever occurs first: Modify the tail strobe power supply wire routing, in accordance with the Accomplishment Instructions of Dassault Mandatory Service Bulletin F900-431, dated November 8, 2011 (for Model Mystere-Falcon 900 airplanes); or Dassault Mandatory Service Bulletin F900EX-437, dated November 8, 2011 (for FALCON 900EX airplanes).
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.
