Panel Wiring Interference 3/2008

Applicability:	Falcon 2000 aircraft serial number (S/N) 01 to 210 inclusive, fitted with a third crew member control panel.
Requirement:	Unless accomplished previously, carry out a detailed inspection of the air gasper installation in the 3rd crew control panel of the LH and RH crew closet for interference and/or damage; and carry out all applicable related corrective actions as instructed in the accomplishment instructions of Dassault Aviation Service Bulletin F2000-316 dated 27 July 2005.

Background:	The aircraft manufacturer has received reports of smoke coming from the crew closet area.  Investigations has discovered a potential for chafing between the rheostat of the 3rd crew member control panel reading light and the air gasper flexible hose, or with the electrical wires nearby.  If let uncorrected, this chafing may expose the metallic spiral armature of the flexible hose, or damage the electrical wires insulation, which could result in a short-circuit generating sustained overheating and smoke emission.
This Directive requires an inspection of the air gasper installation in the 3rd crew control panel of the LH and RH crew closet for interference and/or damage together with applicable related corrective actions.
