At about 1750 Alaska time, a Boeing 727-100 was damaged on approach to Ralph Wien Memorial Airport. No one aboard the Part 121 cargo flight was injured. The operator said that the pilot was on a visual approach when he overshot the runway centerline while turning from base to final. The pilot made a left and a right turn to realign the airplane with the centerline, and during the right turn, the right wing struck the snow-covered ground.
