## Discrepancy

DURING THE DE-PANELING PROCESS ON AIRCRAFT 31035 WE FOUND THE LH EXHAUST STRAP (BAS238-6-1300 CLAMP ASSY (NSCM KB568)) HAD BROKEN LOOSE AND COME TO REST ON THE TAIL ROTOR DRIVE SHAFT, BETWEEN THE FIRE BOTTLES. IT DAMAGED THE DRIVE SHAFT BEYOND REPAIR. THERE ARE SEVERAL AREAS THAT IT HAD RUBBED THE PAINT AND ONE LARGE ARE WHERE THE PAINT HAD BEEN COMPLETELY REMOVED AND BEGAN WEARING INTO THE BASE MATERIAL.  THE LH EXHAUST STRAP (BAS238-6-1300 CLAMP ASSY (NSCM KB568)) HAD BEEN CRACKED FOR SOME TIME. THERE IS A SECTION APPROX 1/8" LONG THAT APPEARS SHINY, WHILE THE REST OF THE STRAP IS SHOWING SIGNS OF BEING CRACKED.
