On December 30, 2008, one of the 15 guy wires on the main transmitter tower snapped, putting the tower in danger of collapsing (as with the 1971 tower collapse, this incident followed a prolonged snow and ice storm). The Portland Police Bureau evacuated about 500 local residents and closed several roads around the tower, including a portion of Skyline Boulevard, the main north-south road through the West Hills of Portland. At first, officials feared that the wire itself—which is over long and weighs several tons—had snapped, which would have taken several weeks to manufacture and install a replacement. Upon inspection, it was revealed that one of the high frequency insulators incorporated into the guy wire assembly had shattered. Repair crews replaced the insulator by 4:00 p.m. the next day and the surrounding neighborhood was reopened to residents and car traffic. KOIN had to pay $1,500 to the Federal Communications Commission (FCC).
