FLC OF MD83 MAKING A CAT II LNDG HAS LOSS OF ACFT CTL DUE TO RWY COVERED WITH SNOW AND ICE. BRAKING RPTED AS FAIR BUT ACTUALLY NIL.

Narrative

I WAS FLYING AS FO IN AN MD80. THE FLT WAS FROM SEA TO ANC. WX IN ANC WAS 600 FT OVCST; 1/4 MI VISIBILITY WITH BLOWING SNOW AND MIST. THE WIND WAS 330 DEGS AT 14 KTS; AND WE WERE LNDG RWY 6R. RWY 6R WAS COVERED WITH SNOW AND ICE WITH BRAKING ACTION RPTED AS FAIR. BECAUSE OF THE LOW WX MINIMA; AND THE FACT THAT THE CAPT WAS RESTR TO A CAT II LNDG (DUE TO BEING A NEW CAPT); WE FLEW A CAT II AUTOLAND APCH. THE APCH WAS NORMAL AND THE AUTOLNDG WAS NORMAL. UPON ROLLOUT THE ACFT DEVIATED (1/4 DOT RMI) FROM THE CTRLINE (ALSO NORMAL); AND INITIATED A CORRECTION N. THE CORRECTION WAS CORRECT AND WITHIN NORMAL LIMITS; BUT THE ACFT BEGAN TO SLIDE TOWARD THE N SIDE OF THE RWY. THE CAPT DISCONNECTED THE AUTOPLT AND TOOK OVER MANUALLY. BRAKING AND STEERING WERE INEFFECTIVE; SO THE ACFT WAS BROUGHT TO A STOP AND DIRECTIONAL CTL MAINTAINED USING DIFFERENTIAL REVERSE THRUST. THE ACFT RAN OVER AND DESTROYED 5 RWY EDGE LIGHTS. THE ACFT WAS INSPECTED ON THE TXWY BY MAINT AND NO DAMAGE WAS FOUND. CONTRIBUTING FACTORS WERE BALD; BUT WITHIN LIMITS OF WEAR; MAIN TIRES. A 14 KT XWIND AND A RWY BRAKING CONDITION OF NIL; BUT RPTED AS FAIR. ADDITIONAL FACTORS MAY BE ATTRIBUTED TO THE FEDERAL REQUIREMENT THAT THE LOW TIME CAPT MAKE A CAT II AUTOLAND. THE CAT II AUTOLAND RESTRICTS THE PLT FROM DEVELOPING A FEEL FOR THE ACFT UNTIL AFTER LNDG. A CAT II LNDG FROM AN ILS; THAT IS; NOT AN AUTOLNDG; MIGHT HAVE PREVENTED THE RWY DEV.
