## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

IRREGULARITY REPORTS COMPLETED BY BOTH PILOTS INDICATED THAT THE AIRCRAFT ENCOUNTERED SEVERE ICING CONDITIONS WHILE ON FINAL APPROACH. THEY BELIEVE THAT THIS CAUSED THE AIRCRAFT TO ROLL TO THE LEFT AND STALL. THE CAPTAIN STATED THAT HE USED FORWARD CONTROL PRESSURE AND NORMAL RECOVERY TECHNIQUES TO REGAIN CONTROL. AN INTERVIEW WITH THE CAPTAIN DISCLOSED THAT THE AIRCRAFT DID ENCOUNTER SEVERE ICE AND ROLLED TO THE LEFT AFTER BEING CONFIGURED FOR LANDING. AT THIS TIME THEY WERE STILL IN IMC. NO BUFFET, STICK SHAKER, OR PUSHER WAS FELT. THE AIRCRAFT PROBABLY DID ROLL BUT THE ACTUAL CAUSE OF THE EXCURSION REMAINS UNCLEAR. THE PILOT RECOVERED QUICKLY AND THEY WERE IN VMC AT THE TIME OF RECOVERY. NTSB HAS ALL THE RECORDERS. NO FURTHER ACTION REQUIRED.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
