What happened
During the approach, weather conditions were reported at approach minimums, characterized by snow and blowing snow. The flight crew successfully acquired the runway environment at or above decision height.
However, upon touchdown, a whiteout occurred, which reduced forward visibility to zero. As the captain was piloting the aircraft, the loss of visual reference to the runway led to an inability to maintain directional control. The aircraft drifted to the right, causing the right main landing gear to contact deep snow. The aircraft eventually came to rest in waist-deep snow approximately 100 feet off the runway.
There were no injuries reported among the three crew members or the 25 passengers. The incident resulted in damage to the nose landing gear.
