Probable cause

The pilot did not adequately compensate for the cross wind conditions while taxiing and failed to maintain clearance between the airplane and a tree on the shoreline. The crosswind was a factor related to the accident.

Sequence of events

Analysis

The pilot reported that turbulent conditions were encountered while on final approach. Due to this condition, a landing on the water was made closer to the shore than intended. During the taxi to the dock in a cove, the airplane drifted to the left where the left wing came in contact with a tree along the shore opposite the dock. The pilot reported that there were no mechanical failures or malfunctions with the airplane at the time of the accident.
