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 he and a passenger had departed for a local sight-seeing flight and while flying low over a river the left wing impacted the water. The impact “pulled the plane into the river,” which resulted in substantial damage to the forward fuselage, wings, and tail structure. The pilot reported that there were no pre-accident mechanic malfunctions or failures with the airplane that would have precluded normal operation.
