FLC FAILS TO ASSURE ENG INTAKE PLUGS HAVE BEEN REMOVED FROM THE ENGS FOR START.

Narrative

THE MORNING OF NOV/XA/95 MY FO AND MYSELF BEGAN OUR FIRST FLT OF THE DAY DUTIES. I DID A WALK AROUND PRIOR TO ACFT ENTRANCE AND THE FO DID HIS NORMAL DETAILED PREFLT INSPECTION. AFTER COMPLETION OF THE PREFLT WE BEGAN AND COMPLETED THE ACCEPTANCE CHK FIRST FLT ITEMS. AT THIS POINT WE WERE READY FOR START. BOTH ENGS STARTED AND RAN NORMAL. AFTER COMPLETION OF MOST ITEMS ON THE BEFORE TKOF CHK WE HAD YET TO COMPLETE THE NTS CHK. AS I BEGAN TO BRING THE ENG UP TO THE REQUIRED RPM I HEARD A LOUD NOISE WHICH CAME FROM THE ENG; I IMMEDIATELY SHUT IT DOWN AT THIS POINT. AFTER SHUTDOWN OF THE REMAINING ENG AT THE GATE; THE RAMP PERSONNEL BROUGHT TO MY ATTN THAT WE STILL HAD THE ENG OIL COOLER DUCT PLUG STILL IN; WHICH ALSO MEANT THE ENG INLET PLUG WAS ALSO IN. THIS WAS THE REASON FOR THE LOUD NOISE THAT MADE ME SHUT THE ENG DOWN. THE ENG INGESTED THE INTAKE PLUG. THE RAMP PERSONNEL ARE RESPONSIBLE FOR OVERNIGHTING AN ACFT WHICH INVOLVES INSERTING THE PLUGS INTO THE ENGS. THE MORNING RAMP PERSONNEL ARE ALSO RESPONSIBLE FOR PULLING OUT THE PLUGS AND PLACING THEM IN THE BAG WHERE THEY BELONG. THE FO NOTICED THE PLUG IN THE L ENG DURING PREFLT; HOWEVER; DID NOT REMOVE IT. HE ASSUMED THAT IT WAS THE RAMP'S RESPONSIBILITY TO REMOVE THEM AND DID NOT WANT TO INTERFERE WITH THEIR JOB DESCRIPTION. THIS WAS NOT BROUGHT TO MY ATTN. THE RAMP PERSONNEL ON DUTY THAT MORNING SAID HE DID NOT SEE ANY PLUG IN THE L ENG; HOWEVER; DID PULL THEM OUT OF THE R ENG. UNFORTUNATELY; THE FO SAW THE PLUG BUT IT WAS AFTER THE RAMP GUY HAD ALREADY DID HIS MORNING PROCS. APPARENTLY THE FO DID NOT REALIZE THAT THE RAMP GUY WAS FINISHED WITH THEIR MORNING PREPARATION OF THE ACFT. THE END RESULT WAS A SERIOUSLY DAMAGED ENG DUE TO AN INGESTION OF AN INLET PLUG. OTHER FACTS: IT WAS XA45 AM; DARK; WE WERE CONTINUOUS DUTY ALL NIGHT (FATIGUE).
