PIPER PA-31-310
THE AIRCREW DID NOT KEY THE APPROACH LIGHTS ON DURING THE FIRST ILS APPROACH AT NIGHT. THEREFORE, A MISSED APPROACH WAS MADE. ON THE SECOND APPROACH, THE LEAD-IN LIGHTS WERE VISIBLE FROM OVER ONE MILE. HOWEVER, THE VISIBILITY WAS MUCH WORSE AT TOUCHDOWN, WHICH WAS ON THE LEFT SIDE OF THE RUNWAY. THE LEFT MAIN GEAR ENCOUNTERED SNOW AT THE EDGE OF THE RUNWAY AND THE AIRCRAFT SWERVED LEFT INTO A SNOWBANK. THE SNOWBANKS WERE ABOUT 4 FEET HIGH AND WERE LOCATED APPROXIMATELY 10 FEET OUTSIDE OF THE RUNWAY LIGHTS. THE PILOT REPORTED THAT THERE WERE NO NOTAMS CONCERNING THE SNOWBANKS. THE 2221 CST WEATHER OBSERVATION AT ST. LOUIS WAS TAKEN ABOUT 15 MILES AWAY AND INDICATED VISUAL METEOROLOGICAL CONDITIONS. HOWEVER, THE PILOT REPORTED THE VISIBILITY WAS VARIABLE BETWEEN 1/2 AND 3 MILES.
