A proposed FAA Airworthiness Directive targets the Embraer Phenom  100’s angle-of-attack (AOA) system. The FAA believes the accumulation of  moisture between the AOA vane base assembly and the stationary ring of  the sensor’s body can freeze under certain conditions. If freezing  occurs both AOA sensors may get stuck and the stall warning protection  system will no longer be effective, potentially resulting in aerodynamic  stall and loss of airplane control.
