Analysis

The PIC stated that the acft was struck by a gust of wind, and he lost control. The PIC applied rt rudder towards a 1OFT ditch in an att to get over it. The acft was too heavy to fly over the ditch and the acft impacted into the ditch. A review of wx cond's obtained fm the FAA flt svc stn at jonesboro, AR, indicated that winds were fm the southwest at 10 knots. Further review indicated that for the hr before and the hour following the rptd time of the acc, the wind had not chg'd dir, or wind spd fm that rptd by the flt svc stn. The PIC rptd no mechanical control difficulty or malf during the takeoff roll or subsequent to the acc.
