From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry 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.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

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.
