Analysis

The plt stated that after a normal approach, touchdown & initial roll-out, the acft veer right & struck a 3 to 4 ft snowbank. An investigation revealed that snow had been falling for over 12 hrs & an 80 ft wide path had been plowed down the center of the ruwway. There was 3 inches of snow remaining in the plowed area. No ice was reported, but the braking action was reported as nil. The plt reported that a previous ice storm had deposited 1/4 to 1/2 inch of ice on the runway before snow began to fall. The presence of ice had been indicated earlier in the day when a Boeing 737 had slid off of a taxiway. The plt stated that had he known about the ice, he would not have landed.
