Narrative

WE HAD EXCEEDED TYPE ONE HOLDOVER TIME AND RETURNED TO GATE FOR DEICE. NUMBER TWO START WAS NORMAL WITH A R QUARTERING XWIND. ON BOTH STARTS WE WERE CONCERNED ABOUT HOT STARTS DUE TO QUARTERING TAILWIND AND THE INADVERTENT INTRODUCTION OF TYPE 1 INTO THE INTAKES. NUMBER ONE START BEGAN NORMALLY BUT THE ITT SLOWLY ROSE TO 701 DEG CELCIUS BEFORE RECEDING. AS IT RECEDED; THE 'ENG INDICATION NO DISP' CAUTION WAS FOLLOWED BY A 'ENG INDICATION SHORT DISP' ADVISORY. DURING DISCUSSIONS WITH MAINT OPS WE READ OFF AND INCLUDED IN THE MEL THE FOLLOWING CMC MESSAGES: ENG INDICATION DISPLAY L FAULT; ST ENG CTL A SYS; ST ENG CTL B SYS NUMBER ONE N2 DISPLAYED DASHED VICE A NUMBER AND THE FADEC WAS BLANK; NO A OR B INDICATED. THE NUMBER TWO SIDE WAS COMPLETELY NORMAL DURING AND AFTER ENG START AND ON SUBSEQUENT SHUTDOWN. AFTER DISCUSSION WITH MAINT OPS AND DISPATCH WE DEPLANED THE PAX AND I FAXED ALL THE DATA TO MAINT OPS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE #1 ENG STARTED AND OPERATED NORMALLY AFTER THE FIRST DEICING; AND AFTER THE SECOND DEICING IS WHEN THE ENG AUTO SHUT DOWN. THE CREW IS CONCERNED THE PROB WITH THE ELECTRONIC ENG CTL FAILURE MAY HAVE BEEN CAUSED BY DEICING FLUID ON OR IN THE INLET SENSORS.
