Probable cause
The pilot’s decision to land on an unmaintained runway surface, which resulted in a loss of control and nose over.
Findings · 3
NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.
Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
Analysis
The pilot reported that on his third pass over the “unplowed” runway, he allowed the main wheels to touch down on the snow. Subsequently, the nosewheel impacted the snow, “folded back”, and the airplane nosed over, coming to rest inverted. The airplane sustained substantial damage to the fuselage and right wing. The pilot reported no preimpact mechanical failures or malfunctions with the airplane that would have precluded normal operation.
