Narrative:

After touchdown on the runway, the plane started going to the left. Right rudder was applied but it didn't help. Right brake was also applied but the plane continued left off the runway. Plane continued going to the left in the dew wet grass tapering down to a ditch, and just before completely stopping, finally slipped into the ditch. I would like to advise you further, if and when we find the reason we could not steer the plane to the right, as we feel something happened to the nosewheel steering. Callback conversation with reporter revealed the following information: a frozen bearing was found in the nose gear which rendered nosewheel inoperative. When the aircraft entered the ditch, the nose gear was damaged and the propeller was bent.
