Beschrijving:
A Beechcraft 1900D, N854CA, operating US Airways Express flight 4479, was substantially damaged while landing at the Saranac Lake-Adirondack Regional Airport (SLK), New York. There were no injuries.
The airplane touched down on runway 23 following an ILS approach with the wing flaps at approach. About 2 seconds after touchdown, the heading changed about 1.5 degrees nose right, and then returned to the touchdown heading over the next several seconds. About 9 seconds after touchdown, the heading changed about 4 degrees right followed by a change to the left of 38 degrees over 6 seconds. The airplane skid to the left and came to a stop perpendicular to the runway.

A Notice To Airman (NOTAM) stated that the runway at the Adirondack Regional Airport was plowed full length and width. The runway description stated, "patches of ice covered with 1/4 inch of snow, braking action poor."

Probable Cause:

PROBABLE CAUSE: "The inadequate snow removal from the runway by airport personnel which left a snow bank extending onto the runway."
