## Analysis

THE ACFT SWERVED OFF THE RUNWAY INTO SOFT TERRAIN AND COLLAPSED THE MAIN GEAR DURING LANDING. THE PILOT STATED THAT A NORMAL LANDING WAS MADE AFTER WHICH THE LEFT TIRE BLEW OUT AND THE ACFT SWERVED OFF THE RUNWAY. EXAMINATION OF THE TIRE AFTER THE ACCIDENT SHOWED THE TIRE WAS FLAT BUT THERE WAS NO EVIDENCE OF A BLOWOUT.
