What happened

NTSB summary, verbatim

Prior to the flight landing on runway 6R, airport maintenance crews reported ice on runway 6L and the possibility of ice on runway 6R. A local air traffic controller relayed the information on possible runway conditions on runway 6R to the flight crew prior to landing; there were no braking action advisories in effect. While landing, the airplane departed the left side of runway 6R several hundred feet from the intersection of runway 6R and runway 36, coming to a stop on runway 36 facing northeast. Airport damage consisted of a damaged runway distance remaining marker. There were no injuries to the passengers or crew and the airplane suffered damage to the left main gear door, auxiliary gear door, and the No. 2 main tire. A special weather observation taken after the incident reported wind from 070 at 8 knots, visibility of 7 miles in light freezing rain, an overcast ceiling at 1,900 feet above ground level, a temperature of -4 degrees Celsius, a dew point of -8 degrees Celsius, with the altimeter indicating 30.10 inches of mercury. Freezing rain began about 3 minutes prior to the incident and an accumulation of .01 inches of snow had fallen in the 14 minutes prior to the start of the freezing rain.

Probable cause

the Board's determination
The pilots' lack of consideration for developing and known weather conditions en route to and at the destination airport, resulting in a runway excursion and subsequent incursion.
