Airworthiness Directive · Amendment 39-17002 · Fuel
DASSAULT AVIATION Airplanes
This AD applies to DASSAULT AVIATION Model MYSTERE-FALCON 900 airplanes, certificated in any category, all serial numbers.
We are adopting a new airworthiness directive (AD) for all DASSAULT AVIATION Model MYSTERE-FALCON 900 airplanes. This AD was prompted by multiple reports of fuel leakage from a defective fuel high-level sensor located in the wing front spar. This AD requires inspecting to determine fuel quantity sensors part numbers and replacing of certain fuel quantity sensors with new fuel quantity sensors. We are issuing this AD to prevent internal fuel leakage with significant fuel vapors, which could result in a fire hazard.
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 440 flight hours or 9 months after the effective date of this AD, whichever occurs first, do the actions specified in paragraphs (g)(1) and (g)(2) of this AD.
(1) Inspect the fuel quantity sensors to determine whether part number (P/N) 722105-2 is installed.
(2) Replace all P/N 722105-2 fuel quantity sensors with new P/N 722105-3 fuel quantity sensors, in accordance with the Accomplishment Instructions of Dassault Mandatory Service Bulletin F900-410, dated December 20, 2010.
As of the effective date of this AD, no person may install a fuel quantity sensor having P/N 722105-2 on any airplane.
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.
