NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.
According to the pilot, while flying over a river at an altitude of about 100 feet above water and ground level, at 250 knots, the airplane impacted unmarked power line wires that spanned the river. The power line wires are clearly identified on the Visual Flight Rules Sectional Aeronautical Chart. The pilot immediately established a climb and returned to the airport without further incident. The airplane sustained substantial damage to the nose, left wing, and vertical stabilizer.
The pilot reported that there were no pre-impact mechanical failures or malfunctions that would have precluded normal operation.
The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot's inadequate preflight planning and subsequent failure to remain clear of power line wires while maneuvering at low altitude.
