NTSB reports (from initial FDR and CVR readout) that plane was at FL160 and requested descent to FL120 to clear haze. ATC cleared them to FL110. Pilots discussed significant ice buildup on the wings and windshield. Aircraft deice was selected just prior to these comments.
1 minute prior to the end of recording, landing gear was selected down. 20 seconds later, flaps 15 were selected. Immediately following flaps to 15, a series of violent pitch and roll excursions occurred. The pilots tried to raise the gear and flaps prior to impact.
