At about 1630 eastern time, a Cessna P206 was damaged while taxiing for takeoff at Newport State Airport. The pilot was not injured. The pilot said he was taxiing behind a King Air with its engines operating. As he passed, the King Air mechanic running the engines moved the propellers from feather to the governing range. The King Air was facing into the wind, which was from 300 at 16 knots, gusting to 20. The combination of wind and propeller thrust from the King Air apparently was enough to flip the Cessna on its back.
