VOID TIME EXPIRED PRIOR TO DEP.

Narrative

ON IFR TRNING FLT; INSTR ALLOWED THE STUDENT TO CONTACT CLRNC DELIVERY ON THE TELEPHONE TO OBTAIN AN IFR CLRNC. STUDENT RECEIVED A VOID TIME WINDOW OF XX+5Z AND WAS TOLD WHAT THE TIME WAS AT THAT MOMENT ACCORDING TO THE CLOCK USED BY APCH. AT THE T IME; THE STUDENT FAILED TO CHK THAT TIME AGAINST HIS WATCH. PRIOR TO TKOF; STUDENT ASKED INSTR WHAT TIME IT WAS; TO WHICH THE INSTR REPLIED XX45; ACCORDING TO HIS WATCH. UPON CONTACTING BRADLEY APCH CLBING THROUGH 2000' MLS; THE CTLR ADVISED THAT IT WAS 5 MINS PAST THE TKOF VOID TIME; STATING THAT IT WAS X50Z. A CHK AT THAT TIME REVEALED THAT THE INSTR'S WATCH WAS 4 MINS SLOW. THE INCIDENT COULD HAVE BEEN AVOIDED BY THE INSTR SYNCHRONIZING TIMES WITH THE STUDENT THE MOMENT CLRNC DELIVERY GAVE HIM (THE STUDENT) THE TIME. THE INSTRUCTOR'S ROLE IS SUPERVISORY AND THUS I ALLOWED THE STUDENT TOO MUCH RESPONSIBILITY IN THE CLRNC PROCESS W/O MONITORING HIS ACTIONS SUFFICIENTLY ENOUGH TO CATCH MISTAKES BEFORE THEY MADE THEIR WAY INTO THE ARWY SYS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: ONCE AIRBORNE; CTLR ASKED IF PLT KNEW IT WAS PAST VOID TIME. WHEN WATCH DISCREPANCY WAS DISCUSSED CTLR CLRED ACFT ON ITS WAY. NO FURTHER COMMENT.
