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.

Aircraft substantially damaged and pilot seriously injured when approximately 3 hours, 325 miles in to a 350 mile IFR cross country flight the engine lost power. Flight data obtained from flight aware shows the aircraft climbed to 9000 feet after takeoff, dropped to 7000 feet 1 hour and 20 minutes into the flight, dropped to 5000 feet 55 minutes later, maintained 5000 feet for 25 minutes before dropping to 4000 feet for the last 12 minutes of the flight. The pilot attempted an emergency landing approximately 25 miles from the destination airport. Surveillance video shows the aircraft touching down on the roof of a building before impacting a road and then a retaining wall. Icing airmets were issued along the route of flight forecasting moderate icing between freezing level and FL260. Freezing level forecast between 3,000’ MSL and 13,000’ MSL. Winds aloft forecast showed temperatures to be at or near freezing along the route of flight. Tafs along the route of flight forecast rain and ceilings at 500’ AGL. A METAR taken at 0500Z 38NM northwest of the accident location indicated 9 sm visibility, light rain, few clouds at 1,000’ AGL, scattered clouds at 4,900’ AGL, overcast clouds at 6,500’ AGL, temperature 3°c, and dewpoint 02°c. post accident inspection of the aircraft revealed no evidence of any preimpact mechanical malfunctions or failures that would have precluded normal operation.
