## Analysis

THE PLT REPORTS THAT HE WAS MAKING A T&G ON THE 5400 BY 200, ASPHALT RWY. THE WIND WAS LIGHT. THE PLT SAID HE HAD RECONFIGURED THE ACFT FOR TAKEOFF AND WAS ABOUT TO ADVANCE THE THROTTLE WHEN THE ACFT SWERVED TO THE RIGHT AND RAN OFF THE RWY. AFTER LEAVING THE RWY THE RT MLG ENCOUNTERED A TAXIWAY AND THE RT GEAR BROKE OFF. THE RT WING THEN HIT THE GROUND AND WAS DAMAGED. THE WHEELS, TIRES, AND BRAKES WERE EXAMINED AFTER THE ACDT AND NO DIFFICIENCIES WERE NOTED.
