## Analysis

DURING ARRIVAL, A THUNDERSTORM WAS LOCATED ABOUT 6 MI SOUTHEAST OF THE AIRPORT AND ANOTHER WAS ABOUT 8 TO 10 MI NORTHWEST. REPORTEDLY, THE WIND WAS VARIABLE FROM 090 TO 180 DEG AT 10, GUSTING 25 KTS. WHILE LANDING ON A 75 FT WIDE RUNWAY, THE AIRCRAFT BEGAN TO VEER LEFT. NOSE WHEEL STEERING, BRAKES AND RUDDER WERE APPLIED, BUT NOT SUFFICIENTLY (IN TIME AND AMOUNT) TO PREVENT THE LEFT MAIN GEAR FROM GOING OFF THE RELATIVELY NARROW RUNWAY. THE LEFT GEAR ENCOUNTERED MUDDY TERRAIN NEXT TO THE RUNWAY, AND SHORTLY THEREAFTER, THE AIRCRAFT CROSSED A MID-FIELD TAXIWAY. AT THAT TIME, THE LEFT MAIN GEAR COLLAPSED.
