Narrative:

Destination was auw. WX reported as 600 overcast, 2 mi in light freezing drizzle and fog. Actually 400 and 2. Attempted and missed VOR approach. Diverted to nearby cwa. Was told to expect ILS runway 8. Approach proceeded normally. By this time had spent approximately 20 mins accumulating and shedding light to moderate rime ice. Windshield was iced over except for the hot plate section directly in front of the left pilot position. Wind was a left quartering tailwind of 5-10 KTS. Runway was ice covered but ATIS indicated the center 80 ft was sanded. With the left crab angle established early in the approach. Could not see the right side of the runway upon braking out. Had difficulty recognizing and correct for wind drift during transition to visual because of tunnel vision caused by 1) the size of the heated section of windshield, 2) distortion in the heated windshield, and 3) the fact that it was dark. Touched down right of the centerline and immediately slid right and off pavement. Aircraft struck a landing light. Was able to return to the runway and decelerate normally. Damage to 1 propeller blade, right outboard gear door, and right flap. The back course approach was an option but questionable due to the ceiling and back course minimums.

Title: RWY EXCURSION RESULTED FROM TEMPORARY LOSS OF ACFT CTL IN SMT IN A NIGHT OP.

Narrative: DEST WAS AUW. WX RPTED AS 600 OVCST, 2 MI IN LIGHT FREEZING DRIZZLE AND FOG. ACTUALLY 400 AND 2. ATTEMPTED AND MISSED VOR APCH. DIVERTED TO NEARBY CWA. WAS TOLD TO EXPECT ILS RWY 8. APCH PROCEEDED NORMALLY. BY THIS TIME HAD SPENT APPROX 20 MINS ACCUMULATING AND SHEDDING LIGHT TO MODERATE RIME ICE. WINDSHIELD WAS ICED OVER EXCEPT FOR THE HOT PLATE SECTION DIRECTLY IN FRONT OF THE L PLT POS. WIND WAS A L QUARTERING TAILWIND OF 5-10 KTS. RWY WAS ICE COVERED BUT ATIS INDICATED THE CTR 80 FT WAS SANDED. WITH THE L CRAB ANGLE ESTABLISHED EARLY IN THE APCH. COULD NOT SEE THE R SIDE OF THE RWY UPON BRAKING OUT. HAD DIFFICULTY RECOGNIZING AND CORRECT FOR WIND DRIFT DURING TRANSITION TO VISUAL BECAUSE OF TUNNEL VISION CAUSED BY 1) THE SIZE OF THE HEATED SECTION OF WINDSHIELD, 2) DISTORTION IN THE HEATED WINDSHIELD, AND 3) THE FACT THAT IT WAS DARK. TOUCHED DOWN R OF THE CTRLINE AND IMMEDIATELY SLID R AND OFF PAVEMENT. ACFT STRUCK A LNDG LIGHT. WAS ABLE TO RETURN TO THE RWY AND DECELERATE NORMALLY. DAMAGE TO 1 PROP BLADE, R OUTBOARD GEAR DOOR, AND R FLAP. THE BACK COURSE APCH WAS AN OPTION BUT QUESTIONABLE DUE TO THE CEILING AND BACK COURSE MINIMUMS.
