Read the full NTSB narrative

THE CREW REPORTED HEAVY MIXED ICING CONDITIONS ON THE WINDSCREEN AND SOME ICE AFT OF THE DE-ICE BOOTS DURING A DESCENT THROUGH 15,500 FEET, FOLLOWED BY TWO UNCOMMANDED LATERAL CONTROL MOVEMENTS. THE PILOTS SAID THE CONTROLS WERE STIFF AND THEY FELT A 'BUZZING' SENSATION IN THE AILERON AND RUDDER CONTROLS. THE AUTOPILOT WAS NOT ENGAGED AT THE TIME AND THE AIRCRAFT WAS IN A CLEAN CONFIGURATION. THE CREW DID NOT REPORT ANY TURBULENCE UNTIL REACHING LOWER ALTITUDES. SOME PASSENGERS REPORTED NO SIGNIFICANT TURBULENCE OR NOTHING EXCESSIVE, WHILE OTHER PASSENGERS DESCRIBED THE TURBULENCE AS 'SCARY' OR 'TOO MUCH'. EXAMINATION OF THE FLIGHT CONTROLS, ASSOCIATED SYSTEMS AND EQUIPMENT REVEALED NO MALFUNCTIONS. THE FLIGHT DATA RECORDER WAS ANALYZED AND THE DATA REVEALED SOME LATERAL CONTROL MOVEMENT THAT IS USUALLY ASSOCIATED WITH TURBULENCE.
