Summary

We propose to supersede Airworthiness Directive (AD) 2008-19- 08, for all Dassault Aviation Model Falcon 10 airplanes. AD 2008-19-08 currently requires repetitive replacement of the flexible hoses installed in the wing (slat) anti-icing system with new hoses. Since we issued AD 2008-19-08, additional reports were received of collapse of the flexible hoses installed in the slat anti-icing systems on airplanes equipped with new, improved hoses. This proposed AD would require reducing the life limit of these flexible hoses, which would reduce the repetitive replacement intervals. We are proposing this AD to prevent collapse of the flexible hoses in the slat anti-icing system, which could lead to insufficient anti-icing capability and, if icing is encountered in this situation, could result in reduced controllability of the airplane.
