Narrative:

During landing rollout on runway 9R at fcm, slippery conditions caused the aircraft to skid off the far end of the runway. No damage caused to the aircraft and no passenger injuries. Contributing factors to this incident were: 1) snow conditions on runway. 2) touchdown speed too high. At the time of landing, ATIS at fcm called the WX 100 obscured 1/16 mi visibility in light snow and fog with braking conditions poor. Nearby stations at msp and stp were both reporting 300 obscured 1/2 mi visibility in light snow and fog. Actual ceiling and visibility on descent to landing on ILS 9R was 400 ft and 3/4 mi. Braking action was worse than indicated by ATIS and hampered further by my high touchdown speed (20 mph high). Corrective action on my part will be to control airspeed more closely when landing on a slippery runway if unable to avoid slippery conditions. Also, finding the actual ceiling and visibility so different from ATIS reports should have caused me to execute a missed approach and land at the alternate airport.

Title: RWY EXCURSION.

Narrative: DURING LNDG ROLLOUT ON RWY 9R AT FCM, SLIPPERY CONDITIONS CAUSED THE ACFT TO SKID OFF THE FAR END OF THE RWY. NO DAMAGE CAUSED TO THE ACFT AND NO PAX INJURIES. CONTRIBUTING FACTORS TO THIS INCIDENT WERE: 1) SNOW CONDITIONS ON RWY. 2) TOUCHDOWN SPD TOO HIGH. AT THE TIME OF LNDG, ATIS AT FCM CALLED THE WX 100 OBSCURED 1/16 MI VISIBILITY IN LIGHT SNOW AND FOG WITH BRAKING CONDITIONS POOR. NEARBY STATIONS AT MSP AND STP WERE BOTH RPTING 300 OBSCURED 1/2 MI VISIBILITY IN LIGHT SNOW AND FOG. ACTUAL CEILING AND VISIBILITY ON DSCNT TO LNDG ON ILS 9R WAS 400 FT AND 3/4 MI. BRAKING ACTION WAS WORSE THAN INDICATED BY ATIS AND HAMPERED FURTHER BY MY HIGH TOUCHDOWN SPD (20 MPH HIGH). CORRECTIVE ACTION ON MY PART WILL BE TO CTL AIRSPD MORE CLOSELY WHEN LNDG ON A SLIPPERY RWY IF UNABLE TO AVOID SLIPPERY CONDITIONS. ALSO, FINDING THE ACTUAL CEILING AND VISIBILITY SO DIFFERENT FROM ATIS RPTS SHOULD HAVE CAUSED ME TO EXECUTE A MISSED APCH AND LAND AT THE ALTERNATE ARPT.
