THE PILOT WAS ATTEMPTING TO LAND ON AN ISLAND AIRPORT. HE MADE A LOW PASS TO BLOW LOOSE SNOW OFF ON THE RUNWAY. AS HE WAS CLIMBING OUT, HE LOST THE HORIZON, AND BEGAN A TURN BACK TO THE AIRPORT. HE BECAME DISORIENTED DURING THE TURN, AND DRAGGED A WINGTIP ON THE FROZEN LAKE. THE AIRPLANE FLIPPED ONTO ITS BACK AND SLID TO A STOP.

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.
