Incident Overview
An aircraft was observed flying at a very low altitude over a lake, executing a series of maneuvers that witnesses described as stalls and recoveries. The aircraft would climb steeply to approximately 150 feet above the lake and then drop sharply back down, coming within a few feet of the water. Upon reaching the south shoreline, where a forest of trees grew to an estimated height of 100 feet, the aircraft pulled up abruptly.
Witness Account
Witnesses stated that as the aircraft neared the tree line, it appeared to stall and roll sharply to the left before descending into the trees. The maneuvers over the lake had involved repeated cycles of climbing and dropping, suggesting intentional low-altitude stall practice.
Investigation Findings
Examination of the wreckage revealed no evidence of a mechanical malfunction or failure of the aircraft structure, flight controls, engine, or propeller prior to impact. The cause of the stall and subsequent collision with trees remains undetermined based on available information.
