Analysis

The pilot stated that during landing roll, after slowing the aircraft to approx 40 KTS the aircraft swerved off of the runway following activation of the nose wheel steering. The pilot related that the nose wheel steering system malfunctioned on two previous occasions, both following flight in icing conditions. Post crash examination of nose wheel steering failed to disclose any preexisting failure or malfunction.
