Primary finding
Probable cause
The pilot’s failure to see and avoid power lines while maneuvering at a low altitude.
Investigator assessment
Analysis narrative
The pilot reported that, about 50 ft above the ground during a "low recon" over a river bar, he did not see power lines crossing the river until they were about 10 ft in front of the airplane. Subsequently, the airplane's empennage struck the wires; he then added power and initiated a climb. He returned to the airport and landed without further incident. The airplane sustained substantial damage to the empennage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
