The lines were de-energized.
Authorities say a 65-year-old pilot escaped injury after his plane hit and became entangled in power lines southwest of the Twin Cities.
Minnesota Public Radio News reports it happened just before 4 p.m. Saturday in Louisville Township, south of Shakopee.
The Scott County Sheriff's Office says the single-engine Piper Cub was suspended upside down after striking the power lines.
Authorities say crews de-energized the lines, allowing pilot Thomas Koskovich, of Shakopee, to be rescued from the plane.
The sheriff's office says Koskovich was not injured.
The Federal Aviation Administration is investigating.
