THE PLT ENCOUNTERED A LINE OF THUNDERSTORMS BEFORE REACHING HIS DESTN. HE DIVERTED TO ACKERMAN, MS, & CIRCLED THE ARPT TO DETERMINE THE WIND. THE WIND SOCK INDCD TO HIM THAT THE WIND WAS CALM. JUST BEFORE LNDG ON RWY 5, HE NOTICED A 'DOWNWIND CURRENT', BUT THE ACFT WAS CONFIGURED WITH THE LANDING GEAR & FULL FLAPS EXTENDED & IT WAS IN A NOSE HIGH ATTITUDE. THE PLT RPRTD THAT BY THIS TIME, THE ACFT WAS BEHIND THE POWER CURVE, THUS MAKING A GO-AROUND IMPOSSIBLE. IT TOUCHED DOWN BEYOND MIDFIELD & MAX BRAKING WAS APPLIED, BUT THE PLT WAS UNABLE TO STOP ON THE REMAINING RWY. THE ACFT CONTD OFF THE DEP END, HIT POTHOLES ON THE OVERRUN AREA & WAS DAMAGED. AFTER THE LANDING, AN EXAM OF THE WIND SOCK REVEALED IT WAS IN A STATE OF DISREPAIR WITH MOST OF THE FABRIC MISSING.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

THE PILOT'S SELECTION OF THE WRONG RUNWAY AND HIS IMPROPER INFLIGHT PLANNING/DECISION WHICH RESULTED IN A SITUATION FROM WHICH HE COULD NEITHER GO-AROUND NOR STOP ON THE REMAINING RUNWAY. THE THUNDERSTORMS, INOPERATIVE (DISREPAIRED) WIND SOCK, AND ROUGH TERRAIN (POTHOLES) WERE CONTRIBUTING FACTORS.
