The private pilot was making an instrument approach at night in instrument meteorological conditions. The control tower advised that packed snow and moderate braking were reported on the runway. The pilot reported that the approach was on speed and the airplane initially touched down smoothly. When the nosewheel touched down, the airplane yawed to the left, and the pilot's efforts to maintain directional control were not successful. The airplane slid on the surface, departed the left side of the runway, and spun around, then the right wing tip and canard contacted the ground, resulting in substantial damage to the right wing, canard, and aileron.
Postaccident examination revealed both nose gear tires were deflated, and the right main tire had low air pressure. However, the pilot did not report any pre-accident mechanical malfunction or anomaly with the airplane that may have precluded normal operation.
Probable Cause: The pilot's loss of directional control on the snow-covered runway, which resulted in a runway excursion.
