Monte Rio Fire Chief Steve Baxman said he heard the twin-engine experimental tandem seat aircraft flying low over the Russian River at about 4:30 p.m. when Baxman saw the plane strike at least three high voltage wires, according to the Sonoma County Sheriff's Department.
The aircraft dragged the lines as the plane continued west along the river, according to officials.
The pilot, 57-year-old Joseph Perez of Santa Rosa, flew the craft under the Duncan Mills Bridge before landing the plane on a sandbar, officials said.
The passenger, 22-year-old Adam Perez of Salem, Ore., was treated by authorities for a minor injury to his hand and released at the scene, according to officials.
Perez was uninjured, officials said.
No damage was done to property on the ground where the plane landed, police said.
