Narrative

DEC/WED/02; A B767-200 ACFT DEPARTED ZZZ ARPT BOUND FOR LOS ANGELES. ON TAXI OUT; THE CREW EXPERIENCED AN EICAS MESSAGE 'R ENG EEC PROBE;' THE INDICATION LIGHT WAS ALSO ILLUMINATED. THERE WAS ONE PREVIOUS OCCURRENCE OF THIS FAULT REGISTERED IN THE ACFT HISTORY. THE CREW CONTACTED MY OFFICE THROUGH A COMMERCIAL RADIO PATCH. AS THE ACFT WAS ON THE GND; IT WAS DECIDED TO ATTEMPT A CIRCUIT BREAKER RESET IN ORDER TO CLR THE MESSAGE AND LIGHT. THIS PROVED UNSUCCESSFUL. THE CREW RPTED THAT THE FAULT WAS INTERMITTENT. IT WAS; THEREFORE; DECIDED TO DEFER THE ITEM PER THE MEL. I LOOKED FOR THE REF WHICH I SUBSEQUENTLY PASSED TO THE CREW. THE REF I GAVE THEM WAS MEL 3034F. THIS REF INDICATED NO RESTRS WITH 1 INOP PER ENG. THE ITEM WAS ENTERED INTO THE ACFT LOG VIA COMPUTER. THE INFO WAS SENT TO THE ACFT PRINTER AND THE FLT PROCEEDED TO DEPART. AS I ENTERED MY LOG RECORD AND RECHKED THE PROB; I REALIZED THAT I HAD GIVEN THE INCORRECT MEL REF. I WENT THROUGH THE PROB AGAIN LOOKING AT ALL THE AVAILABLE INFO AND FOUND I HAD USED THE INCORRECT PAGE OF THE MEL TO GIVE THE FLC. MY FIRST REACTION WAS TO INFORM THE DISPATCHER OF THE PROB; AS WITH THE CORRECT REF THERE WERE A NUMBER OF FLT RESTRS TO BE APPLIED. I THEN INFORMED THE CREW BY ACARS TFC OF MY MISTAKE. THE CORRECT MEL REF SHOULD IN FACT BE 3034B. THE DISPATCHER WORKED ON THE REQUIRED FLT PLAN ISSUES AND THE CREW HAD REPLIED TO ME THAT THE SYS HAD IN FACT OPERATED WITHOUT FAULT SINCE TKOF. WHICH IS INDEED FORTUNATE; HOWEVER; THE INCORRECT MEL REF WAS APPLIED BY ME TO THE SIT. THE ITEM WAS ASSIGNED TO MAINT DEPT FOR SUBSEQUENT RESOLUTION. THE SYS DID IN FACT OPERATE WITHOUT FAULT FOR THE TRIP.
