What happened
Witnesses observed an aircraft flying approximately two miles north of the destination airport (OCY), traveling east at an altitude of roughly 600 feet AGL. As the aircraft crossed the shoreline and moved over the water, it reached a point about one-half mile offshore before initiating a turn to the south. During this turn, witnesses noted that the aircraft began a descent. This descent continued until the aircraft impacted the water approximately one mile northeast of OCY.
During the event, observers reported hearing engine sounds throughout the duration of the flight. The conditions over the water at the time were described as dark night conditions. The pilot was not recovered following the accident.
The investigation
An examination of the aircraft was conducted, which revealed no evidence of mechanical malfunction.
