## Analysis

ACCORDING TO FAA RECORDS, THE STUDENT PLT RECIEVED A WX BRIEFING AT 1000 CST. AT THAT TIME, THE LATEST WX OBSERVATION AT OTTUMUA, IA, (CLOSEST WX STATION TO BROOMFIELD, IA) SHOWED THE WIND WAS FROM 110 DEGS AT 11 KTS. ABOUT 25 MINS AFTER THE BRIEFING, THE FORECAST WAS AMENDED TO EXPECT WINDS FROM 090 DEGS AT 15 KTS. ARRIVING AT BROOMFIELD THE PLT MADE A GO-AROUND AFTER ENCOUNTERING A STRONG X-WIND ON THE 1ST APCH. HE LANDED AFTER THE 2ND APCH BUT THE ACFT DRIFTED OFF THE LEFT SIDE OF THE RWY & HIT A DITCH. THE UNICOM WAS NOT OPERATIONAL AT THE TIME OF THE ACCIDENT, BUT THERE WAS AN OPERATIONAL WIND SOCK. AN AG OPERATOR ON THE ARPT ESTIMATED THE WIND WAS FROM THE EAST AT 20 TO 30 KTS. THESTUDENT DID NOT CONTACT THE FSS AT OTTUMUA TO UPDATE THE WIND WX INFO.
