Factual narrative

THE ACFT LANDED HARD JUST SHORT OF THE RWY AFTER THE PLT EXPRIENCED ICING PROBLEMS IN FLT. THE AIRSPEED INDICATOR STOPPED WORKING IN FLT SO THE PLT WAS ATTEMPTING A LANDING AND SAYS HE ALSO LOST ENGINE POWER AT ABOUT 30 FT IN THE AIR DURING THE FLARE FOR LANDING. ACCORDING TO THE OPERATOR WHO EXAMINED THE ACFT THE WINGS CONTAINED ICE THAT HAD STREAKS OR MARKS ON IT AS IF SOMEONE TRIED TO REMOVE IT. THERE WAS ENOUGH LEFT HOWEVER TO AFFECT THE LIFTING QUALITIES OF THE WING, NO EVIDENCE WAS FOUND OF AN ENGINE MALFUNCTION.
