The FAA's summary their words, unchanged

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-145 series airplanes. This action requires revising the Performance Section of the Airplane Flight Manual (AFM) to provide the flightcrew with procedures to adjust landing distances for landings performed with the anti-icing system active. This action also requires revising the Limitations Sections of the AFM to prohibit certain types of approaches with the anti-icing system active. This amendment is prompted by a report that increased (i.e., higher than normal) flight idle thrust may occur when the anti-icing system is active. The actions specified in this AD are intended to ensure that the flightcrew is advised of appropriate landing field lengths when operating with the anti-icing system active, and that instrument approaches at certain flap settings are prohibited with the anti-icing system active. Increased flight idle thrust when the anti-icing system is active, if not corrected, could result in landing overrun.
