What happened

Local residents observed the airplane flying low along the river. They reported that it entered a bank in the direction of their residence and at one point the wings were perpendicular to the water. The nose of the airplane suddenly dropped and it descended, ultimately striking the dock and shallow water. The airplane came to rest inverted, partially supported by the boat dock and partially in the river. A postaccident examination of the airframe and engine did not identify any anomalies consistent with a preimpact failure or malfunction. While Diphenhydramine, an over-the-counter antihistamine that commonly results in impaired performance, was found in the pilot’s blood at a level consistent with recent use, the investigation was not able to definitively conclude that the pilot suffered from impairment.

An editorial "what led to it / how to avoid it" analysis for this accident is generated separately and will appear here.
