## Discrepancy

AFTER SEVERAL FLIGHTS AND SUBSEQUENT CHANGE OF PILOTS, THERE WAS NO T5 INDICATION DURING ENGINE START ON NR 2 ENGINE.  DURING VISUAL INSPECTION IT WAS NOTED THAT A STUD HAD BROKEN OFF OF THE THERMAL COUPLE TERMINAL BLOCK TO WHICH EXTERNAL WIRING HARNESS CONNECTS.  THE ENGINE WAS REMOVED, DISASSEMBLED, AND THE T5 THERMAL COUPLE HARNESS REPLACED, WITHOUT FURTHER INCIDENT.
