AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below issues the following Airworthiness Directive (AD) under subregulation 39.001(1) of CASR 1998.  The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.

Dassault Aviation Falcon 2000 Series Aeroplanes
AD/F2000/2  Third Crewmember Oxygen Mask Box  3/2006 DM

Applicability:  Falcon 2000 aeroplanes, serial numbers (S/N) 1 to 226 inclusive, and Falcon 2000EX aeroplanes, S/N 1 to 64 inclusive, without Dassault Aviation modification M2738 or M2739, and equipped with a third crew member passenger-type oxygen mask on the cockpit ceiling.
Requirement:       1. Carry out a detailed inspection of electrical wiring bundles and/or cables in the vicinity of the optional third crewmember ceiling oxygen mask box for chafing and/or damage and, if necessary, accomplish corrective actions.
                   2. Modify the routing and protect the electrical wiring bundles and/or cables in the vicinity of the optional third crewmember ceiling oxygen mask box in accordance with Service Bulletin F2000-332 or F2000EX-92, as applicable or later approved revisions.
                Note 1:  SBs F2000-332 and F2000EX-92 cover Dassault Aviation Modification M2738.
                Note 2:  EASA AD 2006-0003 refers.
                Note 3:  EASA AD 2006-0003 superseded EASA AD 2005-0033, expanding applicability and limiting terminating action to the incorporation of modification M2738.
Compliance:     For Requirement 1 - Within 30 flights, after the effective date of this Directive, but no later than 6 March 2006.
                For Requirement 2 - Before further flight immediately following the Requirement 1 inspection.
                This Airworthiness Directive becomes effective on 6 February 2006.
Background:     The European Aviation Safety Agency (EASA) has advised that a drawing review and associated inspections on aircraft have highlighted a potential chafing risk between the third crew member oxygen mask box, optionally installed in the cockpit ceiling, and feeder cables routed in the area.

   This situation, if not corrected, could generate smoke or fire, which could be fanned by oxygen leakage from the box.  This Directive requires the inspection together with any necessary repairs, modification of the routing and protection of the electrical bundles and/or cables in the vicinity of the third crew member oxygen mask box.
