FAA Proposes New Airworthiness Directive for Yaborã Indústria Aeronáutica S.A. Airplanes

The Federal Aviation Administration (FAA) proposes a new airworthiness directive for certain Yaborã Indústria Aeronáutica S.A. airplanes, specifically the EMB-135, EMB-145, and variants, due to incorrect calculations in the automatic takeoff thrust control system (ATTCS) under certain conditions. The proposed directive requires updating the software of the installed full authority digital engine control (FADEC) systems.
