Approach and Landing
The pilot was cleared for an Instrument Landing System (ILS) approach to Runway 6 and reported sighting the runway above the decision height. Snow was falling during the approach. After what the pilot described as a 'successful' approach, the airplane touched down within the touchdown zone.
Loss of Directional Control
Upon touchdown, the flight crew deployed spoilers, thrust reversers, and brakes. Despite these efforts, the airplane began to drift to the right. The aircraft subsequently exited the runway surface and impacted a snowbank located on the right side of the runway. The impact caused the left main landing gear to collapse and resulted in damage to the fuselage keel beam.
Runway Conditions and Reports
The pilot reported braking action as 'nil.' According to the pilot, the runway was covered with 'two to three inches' of wet snow. The tower controller had previously transmitted to the flight crew that the last braking action report, provided by a Westwind aircraft about 20 minutes earlier, was 'fair.' Additionally, the Automatic Terminal Information Service (ATIS) broadcast indicated that the approach lights for Runway 6 had been decommissioned.
Post-Accident Actions
Immediately following the accident, the runway was closed and plowed.
