COLUMBUS, Ohio (AP) -- The state has disqualified one ride at the Ohio State Fair after inspectors found "visible corrosion" and is reviewing four others. None of the five operated at the fair, which opened Wednesday.

Dorothy Pelanda, director of the Ohio Department of Agriculture, which oversees the fair, said Thursday the four other rides could be re-opened after minor repairs.

The Columbus Dispatch reports Pelanda permanently shut down a Ferris wheel-type ride known as "Military Base" because it showed "visible corrosion." A message seeking comment on the announcement was left with the company that operates the rides.

The state earlier this year replaced about 100 chairs on the fair's overhead SkyGlider and added a braking system.
