Factual narrative
THE PLT REPORTED THAT WHEN HE LANDED, THE ACFT BEGAN DRIFTING TO THE LEFT. SINCE THERE WAS A HIGH SPEED TURN-OFF AHEAD, HE DID NOT MAKE AN IMMEDIATE CORRECTION FOR THE DRIFT. WHEN A CORRECTION WAS APPLIED, THE ACFT DID NOT RESPOND & IT CONTINUED INTO A GROUND LOOP. THE RIGHT MAIN GEAR THEN COLLAPSED UNDER A SIDE LOAD. DURING A REPAIR, THE RIGHT LANDING GEAR CABANE STRUT WAS FOUND TO HAVE BEEN PREVIOUSLY REPAIRED WITH UNDERSIZED MATERIAL.
