On April 15, 2004, an Aeronca 7AC (registration N2908E) operated by William L. Rotenberry was involved in an aviation accident near Carthage, TN. Investigators recorded the probable cause as: The pilot's failure to maintain adequate situational awareness, which resulted in the collision with wires. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A pilot flying near a river struck overhead wires after his passenger warned him, then crashed into the water. The pilot admitted he failed to maintain adequate situational awareness of the surrounding environment.
What happened
The flight was conducted in close proximity to a river corridor. During the operation, the pilot initiated a turn when the passenger observed overhead obstructions and warned him to watch for wires. Despite this warning, the airplane collided with two of four visible wires suspended across the area. Following the impact with the wires, the aircraft continued its trajectory and struck the surface of the river.
The investigation
Post-accident examination revealed that the pilot did not experience any mechanical malfunctions or failures with the airplane prior to the collision with the wires or the subsequent impact with the water. The sequence of events was driven by spatial disorientation or lack of visual scanning rather than equipment failure.
Findings
The primary factor contributing to the accident was the pilot's failure to maintain adequate situational awareness. The pilot later acknowledged that he should have been more alert to his surroundings and the presence of low-hanging obstructions in the flight path.
Probable cause
The pilot's failure to maintain adequate situational awareness, which resulted in the collision with wires.
