THE AIRCRAFT STRUCK THE GROUND IN A WINGS LEVEL ATTITUDE CONTACTING AND EMBANKMENT NOSE FIRST AND THEN COMING TO REST AFTER CROSSING A ROAD. THE DENSITY ALTITUDE AT THE TIME OF THE ACCIDENT WAS APRX 8,800 FT.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
