## Analysis

THE PLT OF THE ACFT BEGAN TO HAVE DIFFICULTY HOLDING ALT SHORTLY AFTER LEVEL-OFF AT 6000 FT MSL. HE STATED THAT IT SOUNDED LIKE THE ENG WAS FLOODING. HE BEGAN A FORCED DESCENT TO THE NEAREST SUITABLE AIRFIELD AND CROSSED OVER THE NDB FOR THAT FIELD AT 3000 FT MSL. DURING A TURN BACK TO THE RWY, THE WINGS AND WINDSCREEN BEGAN TO ICE UP. AT THIS POINT HE BEGAN TO LOSE ALT MORE RAPIDLY. AT ABOUT 20 FT ABOVE THE GROUND, AT 65 KIAS, THE LEFT WING DROPPED AND THE ACFT SETTLED TO THE GROUND SHORT OF THE RWY. THE PLT STATED THAT THE HEAVY SNOW HE HAD BEEN FLYING THROUGH MAY HAVE BLOCKED THE ENG INTAKE AIR FILTER, CAUSING THE ENG PWR LOSS.

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.
