Analysis

Plt stated that after touchdown, acft began a left drift. As plt applied corrective input, he noted the left wheel was in a snow windrow, so additional input was made to break wheel free of window. Left wheel crossed windrow as acft swerved right but plt was unable to arrest swerve before nose gear contacted windrow on right side, collapsing the nose gear. Acft continued off right side of runway, striking VASI lights with both props and the main lndg gear. Plt was aware only center 75 ft of 150 ft wide runway had been plowed and believed touchdown was on runway center. A 130 degree right crosswind of 10-15 KTS existed at the time.
