, o i This event was caused by strain on the instrtment air line causing 5he line,

, to split. Loss of instrtment air caused the cooling fans to fail off and ,

, , i the dampers to fail closed, stopping the flow of cooling air in the cooling, g ; tower. The line was replaced on October 11, 1982. ,
