Aircraft Accident/Incident Report

Duncan Mills, California 95430
Friday, February 15, 2008 16:30 PST

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that he was flying at a low altitude over a river into hazy conditions and looking directly into the setting sun. The pilot stated that as he was preparing to turn to miss a flock of birds the airplane impacted a set of transmission wires, which severed the airframe's wing support structures. The impact with the wires forced the airplane to a lower altitude and under a bridge in the airplane's flight path. After flying under the bridge and exiting on the opposite side, the airplane impacted a second set of transmission wires with the airplane's landing gear legs. The pilot then made a successful forced landing on a river gravel bar and came to rest upright. A witness, who was camping nearby, observed the airplane flying about 20 to 40 feet above the river before going out of sight. The witness reported, "Approximately 5 seconds later I heard a 'large impact,' followed by an electrical discharge sound and the power going out at the campground."

NTSB Probable Cause Narrative

The pilot's failure to maintain clearance with power lines while maneuvering at a low altitude. Contributing factors included the pilot's decision to fly at low altitude and the sun glare condition.
