Incident Overview
A pilot of a Piper PA-46-350P reported that during the execution of an instrument approach to the arrival airport, weather information indicated light winds, and the runway had been plowed and sanded but was covered with light snow and patchy ice. Just after touchdown, the airplane began to drift to the left. The pilot countered with gradual application of right rudder, and the airplane momentarily straightened. However, as ground speed decreased, the left drift continued. The airplane departed the runway and collided with a snow bank, resulting in substantial damage to the firewall.
Sequence of Events
The pilot checked weather for the arrival airport prior to conducting the instrument approach. The conditions reported included light winds, a plowed and sanded runway, and a surface of light snow with patchy ice. Upon touchdown, the aircraft immediately began a left drift. The pilot applied right rudder gradually, which temporarily corrected the drift. As the airplane slowed, the left drift resumed and became more pronounced. The airplane subsequently left the runway and struck a snow bank.
Damage Assessment
The collision with the snow bank caused substantial damage to the firewall. No other damage items were reported.
Pilot Report
The pilot stated that the airplane's drift to the left began just after touchdown and was countered with right rudder. Despite corrective inputs, the drift continued as speed decreased. The pilot did not indicate any mechanical issues or pilot error beyond the reported conditions.
