CLINTON COUNTY — Roadways near the intersection of Missouri Highways C and CC are back open after being closed for nearly three hours by Clinton County Sheriff deputy vehicles while they investigated the scene of plane accident.

Clinton County responders received the emergency call around 6 p.m.

A 2014 experimental and light sport RV12 plane hit a transformer box at the intersection of Highway C and Piper Drive, causing it to flip over, Clinton County Sheriff Larry Fish said.

“It only had one occupant. It was basically a runaway plane,” he said at the scene. “It never left the ground. The individual was just doing maintenance, normal monthly maintenance, and it got away from him.”

The occupant, who remains unidentified as the investigation is ongoing, sustained moderate injuries and was transported to an area hospital for treatment.

The investigation is being conducted by the Missouri Highway Patrol, Clinton County Sheriff’s Office and the Federal Aviation Administration.
