ATX PLT LANDS ON CLOSED RWY AT ANV; AK. OVERFLIES A WORKING GRADER IN THE PROCESS OF SNOW REMOVAL.

Narrative

AT XA00 LCL TIME ON JAN/XX/97; I EXECUTED A LNDG AT THE ANV; AK; ARPT AND HAD TO NEARLY OVERFLY A GRADER PERFORMING SNOW REMOVAL ON THE FIELD. I WAS FLYING A C207 ON A REGULARLY SCHEDULED FLT AND WAS CARRYING 1 PAX. AS I APCHED THE RWY; I MADE ALL THE STANDARD TFC CALLS; INCLUDING 2 ANNOUNCING THAT I WAS ON FINAL FOR RWY 35 AT ANV. THE WX CONDITIONS WERE POOR WITH A 500 FT OVCST; 2 MI VISIBILITY; AND A 20 KT HEADWIND COMPONENT ON SHORT FINAL. A GRADER WAS PERFORMING SNOW REMOVAL JUST OUTSIDE THE LIGHTS ALONG THE W SIDE OF THE RWY ABOUT 150 FT PAST THE APCH THRESHOLD. I MADE A HIGHER THAN NORMAL APCH AND LANDED 1/2 WAY DOWN THE RWY AFTER ELECTING TO OVERFLY THE GRADER. UNKNOWN TO ME; THE ARPT HAD BEEN NOTAMED CLOSED EARLIER THAT MORNING. THE COMPANY CALLS FOR A BRIEFING EVERY MORNING AND REQUESTS NOTAMS. ANOTHER PLT OBTAINED THE BRIEFING THAT MORNING; REQUESTED THE NOTAMS; BUT RECEIVED NONE PERTAINING TO THE ARPT BEING CLOSED. THERE WAS NO 'X' AT THE APCH END OF THE RWY EITHER. I BELIEVE 2 PROBS OCCURRED WITH THIS INCIDENT. FIRST; I LANDED ON A RWY THAT HAD BEEN NOTAMED CLOSED. THE COMPANY RECEIVED NO INFO ABOUT THE CLOSURE EITHER THROUGH FSS OR FROM ITS LOCAL AGENT REGARDING THE RWY CLOSURE. IT IS NOT NORMAL FOR A RWY TO BE CLOSED SIMPLY FOR SNOW REMOVAL UNLESS THE SNOW IS EXCESSIVELY DEEP WHICH THIS WAS NOT. SECOND; I LANDED LONG OVER THE GRADER WITHOUT BUZZING THE GRADER TO ANNOUNCE MY PRESENCE. GIVEN THE WINDY CONDITIONS AND TURB CAUSED BY TERRAIN AROUND THE ARPT; I ELECTED TO MAKE AN EXTRA HIGH APCH AND LAND PAST THE GRADER ON THE SUFFICIENT RWY REMAINING. THE GRADER WAS NOT EQUIPPED WITH A RADIO AND THUS SHORT OF BUZZING THE GRADER I COULD NOT NOTIFY HIM OF MY PRESENCE.
