NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The pilot said he heard a 'slight hesitation or miss' in the engine and increased power slightly. The engine gauges registered normal and the engine seemed to 'smooth out.' He sighted a road below and descended to assess its suitability for a possible forced landing in case the engine lost power. He felt the airplane strike something and shudder, then heard a loud rumbling noise. The airplane struck wires that crossed the road, impacted the roadway, then collided with a bridge.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's inadequate visual lookout and his failure to maintain adequate clearance from obstacles. Factors were an intentional low altitude flight maneuver, wires, and low light conditions.
