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.

Pilot stated that he had left the hanger doors open on Sunday, 12/08/12 and that a layer of snow approx. 8 inches thick had accumulated on the top of the wings after a storm passed through the area. On 12/10/12 the pilotprivacy data omitted pulled the aircraftout of the hanger and into the direct sunlight after the snow storm so that the sun would melt the accumulated snow from the top of the wings. The pilotprivacy data omitted did note that the snow was melted from the wings. The pilot/owner did not return the aircarft to the hanger and left the aircraft outside for the evening in sub zero tempatures. On the morning of 12/11/12 the pilotprivacy data omitted jumped into the aircraft without a complete preflight. And took off to observe his cattle. Immediately after takeoff the aircarft took on a left wing down attitude from which the pilotprivacy data omitted was unable to correct. After losing altitude in a left wing down attitude the aircarft stalled and went into a grove of trees nose down .the left wing of the aircraft struck a large limb causing the aircraft to come to rest upside down in the direction of flight.
