Narrative:
Transition from ILS approach to runway 10, conditions 1200 ft and 1 1/2 mi, winds reported at 040 at 18 KTS, gusting to 30, snow and blowing snow. Airport authority through tower reported runways plowed, snow depth on runway 1/4-1/2' wet snow and sanded, braking action poor by airport authority pickup truck. Prior to touchdown, wind shear was encountered, but was able to keep lined up with centerline of runway. Landed left wing low, initial rollout seemed normal. As right wheel touched down and light application of brakes was made, aircraft began to veer to the right. When the nose wheel touched down and left rudder was applied, this failed to correct the movement of the aircraft. The aircraft stopped when it contacted a 2 ft high 'windrow' of snow, just a few ft to the right (south) of the runway and parallel to the runway. The 'windrow' was primarily from the plowing of the runway. Full left rudder had no effect on stopping the right turn. Talked with tower on aircraft radio and advised them of no injuries.

Title: PLT OF LIGHT TWIN LNDG ON SNOW COVERED RWY AT DPA IN GUSTY CONDITIONS IS UNABLE TO KEEP ACFT FROM DRIFTING OFF RWY AND COLLIDING WITH SNOW BANK AFTER TOUCHDOWN.
Narrative: TRANSITION FROM ILS APCH TO RWY 10, CONDITIONS 1200 FT AND 1 1/2 MI, WINDS REPORTED AT 040 AT 18 KTS, GUSTING TO 30, SNOW AND BLOWING SNOW. ARPT AUTHORITY THROUGH TWR REPORTED RWYS PLOWED, SNOW DEPTH ON RWY 1/4-1/2' WET SNOW AND SANDED, BRAKING ACTION POOR BY ARPT AUTHORITY PICKUP TRUCK. PRIOR TO TOUCHDOWN, WIND SHEAR WAS ENCOUNTERED, BUT WAS ABLE TO KEEP LINED UP WITH CENTERLINE OF RWY. LANDED LEFT WING LOW, INITIAL ROLLOUT SEEMED NORMAL. AS RIGHT WHEEL TOUCHED DOWN AND LIGHT APPLICATION OF BRAKES WAS MADE, ACFT BEGAN TO VEER TO THE RIGHT. WHEN THE NOSE WHEEL TOUCHED DOWN AND LEFT RUDDER WAS APPLIED, THIS FAILED TO CORRECT THE MOVEMENT OF THE ACFT. THE ACFT STOPPED WHEN IT CONTACTED A 2 FT HIGH 'WINDROW' OF SNOW, JUST A FEW FT TO THE RIGHT (SOUTH) OF THE RWY AND PARALLEL TO THE RWY. THE 'WINDROW' WAS PRIMARILY FROM THE PLOWING OF THE RWY. FULL LEFT RUDDER HAD NO EFFECT ON STOPPING THE RIGHT TURN. TALKED WITH TWR ON ACFT RADIO AND ADVISED THEM OF NO INJURIES.
