NTSB Narrative Summary Released at Completion of Accident

While concentrating on flying just beyond the boundary of Class Delta airspace, the pilot focused in on the indications of his Global Positioning System (GPS), and inadvertently entered a low-level overcast cloud layer. Before he was able to initiate a 180 degree turn, the left wing of the aircraft impacted a tree. The pilot estimated that he was in the clouds for less than ten seconds when the aircraft collided with the tree.

NTSB Probable Cause Narrative

the pilot's inadvertent visual flight rules ( VFR) flight into instrument meteorological conditions (IMC) during cruise flight. Factors include his attention being diverted to the indications presented by his Global Positioning System (GPS), and low ceiling and clouds in the area he was transiting.
