Narrative:
During start, the engine was shut down with a maximum egt of 720 degrees C. We contacted maintenance and the engine controller said that an engine change is required. When I commented to captain that we should wait for an automatic shutdown, I felt very uncomfortable because I knew without a doubt that the engine would overtemp. However, I was taught during training (from an instructor with great conviction) that we should 'situation on our hands' and let the automation do its job. I certainly understand the importance, need and value of SOP's. However, I feel there is lacking the encouragement and authority/authorized to use commonsense in our operation. This unfortunate event could have and would have been avoided if commonsense operational techniques were practiced during training along with SOP's. I suggest that at least in the case of hot starts that we advocate to the crews, if a hot start is recognized and is imminent that we manually terminate the start and manually motor the engine instead of relying on the automation, ie, use the automation as a backup.
Original NASA ASRS Text
Title: A320 ENG HAD OVERTEMP EGT DURING AUTO SHUTDOWN DUE TO A HOT START. THE FO RECOMMENDS THAT HOT STARTS SHOULD BE TERMINATED MANUALLY AND THAT THE ENG SHOULD BE MANUALLY MOTORED TO MORE QUICKLY PUT OUT ANY FIRE AND MORE RAPIDLY COOL DOWN THE ENG.
Narrative: DURING START, THE ENG WAS SHUT DOWN WITH A MAX EGT OF 720 DEGS C. WE CONTACTED MAINT AND THE ENG CTLR SAID THAT AN ENG CHANGE IS REQUIRED. WHEN I COMMENTED TO CAPT THAT WE SHOULD WAIT FOR AN AUTO SHUTDOWN, I FELT VERY UNCOMFORTABLE BECAUSE I KNEW WITHOUT A DOUBT THAT THE ENG WOULD OVERTEMP. HOWEVER, I WAS TAUGHT DURING TRAINING (FROM AN INSTRUCTOR WITH GREAT CONVICTION) THAT WE SHOULD 'SIT ON OUR HANDS' AND LET THE AUTOMATION DO ITS JOB. I CERTAINLY UNDERSTAND THE IMPORTANCE, NEED AND VALUE OF SOP'S. HOWEVER, I FEEL THERE IS LACKING THE ENCOURAGEMENT AND AUTH TO USE COMMONSENSE IN OUR OP. THIS UNFORTUNATE EVENT COULD HAVE AND WOULD HAVE BEEN AVOIDED IF COMMONSENSE OPERATIONAL TECHNIQUES WERE PRACTICED DURING TRAINING ALONG WITH SOP'S. I SUGGEST THAT AT LEAST IN THE CASE OF HOT STARTS THAT WE ADVOCATE TO THE CREWS, IF A HOT START IS RECOGNIZED AND IS IMMINENT THAT WE MANUALLY TERMINATE THE START AND MANUALLY MOTOR THE ENG INSTEAD OF RELYING ON THE AUTOMATION, IE, USE THE AUTOMATION AS A BACKUP.
