THE OMISSION OF TWO WELDS THAT CONNECT THE PINTLE HOOK CROSSMEMBER ASSEMBLY TO THE TRAILER SUSPENSION SUBFRAME CAUSES FATIQUE CRACKS TO DEVELOP IN THE CROSSMEMBER. CONSEQUENCE OF DEFECT: PINTLE HOOK CROSSMEMBER COULD SEPARATE FROM THE SUSPENSION SUBFRAME RESULTING IN A TOWED VEHICLE BEING SEPARATED FROM THE LEAD TRAILER WITHOUT PRIOR WARNING. ALSO, LOOSENING OF FASTENERS THAT CONNECT THE BOGIE SUBFRAME TO THE BODY COULD RESULT IN SEPARATION OF THE BOGIE ASSEMBLY FROM THE TRAILER.

TWO WELDS CONNECTING THE PINTLE HOOK CROSSMEMBER ASSEMBLY TO THE TRAILERS SUSPENSION SUBFRAME HAVE BEEN OMITTED. THIS CAUSES CRACKS TO FORM ON CROSSMEMBER WHEN TOWING ANOTHER TRAILER. CONSEQUENCE OF DEFECT: THESE FATIGUE CRACKS WILL RAPIDLY DEVELOP IN THE PINTLE HOOK CROSSMEMBER AND CONTINUE TO GROW UNTIL THE CROSSMEMBER SEPARATES FROM THE TRAILER'S SUSPENSION SUBFRAME. A SEPARATED TOWED VEHICLE WOULD BE OUT OF CONTROL UNTIL ITS EMERGENCY BRAKING SYSTEM BRINGS IT TO A STOP. HOWEVER, AN ACCIDENT MAY OCCUR DURING THE TIME IT IS OUT OF CONTROL.
