Analysis

The student plt stated that on the landing roll with a 7 kt right x-wind, the acft began drifting to the left. Reportedly, he tried to correct with right rudder, but the fire extinguisher had come loose & became jammed under the right rudder pedal. Subsequently, the acft struck a snow berm near the left side of the rwy. According to the plt, the fire extinguisher is normally mounted on the floor in front of the plt's seat & is easy to kick. He reported no mechanical irregularities with the acft except for the fire, extinguisher clamp. At 1635 ast, the wind was reported as calm.
