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.
Narrative: investigation revealed that after leveling at 16,000 feet, the aircraft began to accumulate ice. Airspeed decreased from 200 KIAS to 142 KIAS. Angle of attack reached 12.5 degrees. Autopilot disconnected. Temporary loss of control occurred resulting in 54 degrees of bank. Crew recovered. Lower altitude was requested and aircraft reached better flying conditions. Second in command was the flying pilot that was monitoring ice acretion. Neither pilot detected subtle loss of airspeed. Both pilots retrained and retested and counselled. Proficiency check on pilot in command served as 609 re-examination. This investigation is closed.
