## Analysis

THE PLT REPORTED THE WINDS WERE FROM 160 DEG AT 7 KTS & THAT HE BACK TAXIED ON RWY 14 TO TAKEOFF. HE REPORTED THAT DURING THE TAKEOFF ROLL, HE ENCOUNTERED A RIGHT X-WIND, & WHEN HE WAS APRX 2/3 OF THE WAY DOWN THE RWY, THE ACFT VEERED TO THE LEFT. AFTER DEPARTING THE RWY, THE PLT REDUCED THE POWER TO ABOUT THE TAKEOFF. FEARING THAT TOO MUCH BRAKING WOULD FLIP THE ACFT OVER, HE GENTLY APPLIED THE BRAKES. AFTER SLOWING TO ABOUT 10 KTS, THE ACFT 'NOSED INTO A SMALL CULVERT' & WENT OVER ON ITS TOP. APRX 35 MI NORTHWEST AT DUBUQUE, IA, THE 1252 CDT WIND WAS FROM 270 DEG AT 12 KTS.
