This AD results from information we received from operators and the airplane manufacturer indicating that the repetitive interval for the required replacement deviated from the referenced service information. We are issuing 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.
