Analysis

The pilot reported the flight’s purpose was to fly “low and slow” over the riverbed for a ceremony. During a left turn initiated about 250 ft above ground level, the pilot noticed a sink rate develop. The pilot applied full power, but the sink rate continued, and the airplane struck a tree that resulted in substantial damage to both wings and the fuselage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
