Narrative:
Climbing out from mco at approximately 10000 ft, aircraft suffered a compressor stall. Aircraft was climbing at 250 KTS when yawed and loud popping noise was heard. Was pulled back to idle and egt which had been rising, stabilized at 590 degrees C. We completed the engine compressor stall checklist and requested return to mco. As per our checklist the engine was kept running as no engine parameters were exceeded. Appropriate checklists were accomplished and a vector for visual to runway 17 at mco was accepted. Approximately 2 mi out on final a second compressor stall occurred and minor amount of smoke was noted in the cockpit. The first officer quickly closed the bleed and turned off the left side pack. Smoke immediately dissipated. Aircraft landed without incident and was shut down after exiting runway. Callback conversation with reporter revealed the following information: the captain said that he was flying one of his airline's newest B757-200's when the left engine began to compressor stall. He retarded the engine to idle and decided to return to mco. On short final to runway 17 as the flight crew spooled the left engine up for the landing, the compressor stalled again. They retarded the left engine to idle again and completed the landing. After they got back to the gate, the left engine was shut down during taxi, maintenance personnel found metal bits laying in the tailpipe. The reporter said that he has no more information on what had failed on the engine. He said that the crew had been fairly gentle with the engine because of their light weight on this flight. The flight crew had used reduced takeoff thrust #1 and reduced climb thrust #2 during their takeoff and departure. He felt that this may have allowed the engine to stay together as long as it did.
Original NASA ASRS Text
Title: A B757-200 ACR FLC HAS COMPRESSOR STALLS ON THE L ENG DURING CLBOUT AND RETURN. DURING A POSTFLT INSPECTION LOOSE METAL WAS FOUND IN THE TAILPIPE.
Narrative: CLBING OUT FROM MCO AT APPROX 10000 FT, ACFT SUFFERED A COMPRESSOR STALL. ACFT WAS CLBING AT 250 KTS WHEN YAWED AND LOUD POPPING NOISE WAS HEARD. WAS PULLED BACK TO IDLE AND EGT WHICH HAD BEEN RISING, STABILIZED AT 590 DEGS C. WE COMPLETED THE ENG COMPRESSOR STALL CHKLIST AND REQUESTED RETURN TO MCO. AS PER OUR CHKLIST THE ENG WAS KEPT RUNNING AS NO ENG PARAMETERS WERE EXCEEDED. APPROPRIATE CHKLISTS WERE ACCOMPLISHED AND A VECTOR FOR VISUAL TO RWY 17 AT MCO WAS ACCEPTED. APPROX 2 MI OUT ON FINAL A SECOND COMPRESSOR STALL OCCURRED AND MINOR AMOUNT OF SMOKE WAS NOTED IN THE COCKPIT. THE FO QUICKLY CLOSED THE BLEED AND TURNED OFF THE L SIDE PACK. SMOKE IMMEDIATELY DISSIPATED. ACFT LANDED WITHOUT INCIDENT AND WAS SHUT DOWN AFTER EXITING RWY. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE CAPT SAID THAT HE WAS FLYING ONE OF HIS AIRLINE'S NEWEST B757-200'S WHEN THE L ENG BEGAN TO COMPRESSOR STALL. HE RETARDED THE ENG TO IDLE AND DECIDED TO RETURN TO MCO. ON SHORT FINAL TO RWY 17 AS THE FLC SPOOLED THE L ENG UP FOR THE LNDG, THE COMPRESSOR STALLED AGAIN. THEY RETARDED THE L ENG TO IDLE AGAIN AND COMPLETED THE LNDG. AFTER THEY GOT BACK TO THE GATE, THE L ENG WAS SHUT DOWN DURING TAXI, MAINT PERSONNEL FOUND METAL BITS LAYING IN THE TAILPIPE. THE RPTR SAID THAT HE HAS NO MORE INFO ON WHAT HAD FAILED ON THE ENG. HE SAID THAT THE CREW HAD BEEN FAIRLY GENTLE WITH THE ENG BECAUSE OF THEIR LIGHT WT ON THIS FLT. THE FLC HAD USED REDUCED TKOF THRUST #1 AND REDUCED CLB THRUST #2 DURING THEIR TKOF AND DEP. HE FELT THAT THIS MAY HAVE ALLOWED THE ENG TO STAY TOGETHER AS LONG AS IT DID.
