Narrative:
Engine #1 began surging with erratic EPR, N1, N2 during climb out. Crew decided to return to mco for precautionary landing. During downwind, engine parameters continued, fluctuating with erroneous engine failure warnings. On final approach below 1000 ft, with captain now flying, left engine failed. Landed and then cleared runway. Emergency crew observed left engine smoking and leaking fuel. They recommended deplaning aircraft on taxiway. Main cabin door was used to exit onto portable stairs. Captain and first officer performed emergency shutdown of APU and right engine due to presence of leaking fuel. No injuries, no deployment of slides. Passenger bussed to terminal. Aircraft towed to gate. Callback conversation with reporter revealed the following information: captain reports the crew flew the aircraft the day before. They were unable to start the engine because of a sheared starter shaft. After this was repaired, they were able to start the engine but the generator would not come on line because of a low N2 RPM. The captain feels that the N2 stage was binding and caused the 2 problems. On the next trip sequence the first officer described the symptoms exactly and said he had the same thing happen the yr before. The aircraft uses the rolls royce tay engine. Supplemental information from acn 456750: during initial climb out, #1 engine EPR and tgt began to fluctuate. Shortly thereafter, we received several 'transient' engine failure #1 alerts on MFDU screen, but each alert appeared only momentarily. Decision was made to return to mco with the #1 engine still operating. At approximately 400 ft AGL on approach, engine #1 failed. Checklist items were accomplished and passenger were deplaned via airstairs after clearing runway.

Title: FK10 CREW HAD ENG FAILURE.
Narrative: ENG #1 BEGAN SURGING WITH ERRATIC EPR, N1, N2 DURING CLBOUT. CREW DECIDED TO RETURN TO MCO FOR PRECAUTIONARY LNDG. DURING DOWNWIND, ENG PARAMETERS CONTINUED, FLUCTUATING WITH ERRONEOUS ENG FAILURE WARNINGS. ON FINAL APCH BELOW 1000 FT, WITH CAPT NOW FLYING, L ENG FAILED. LANDED AND THEN CLRED RWY. EMER CREW OBSERVED L ENG SMOKING AND LEAKING FUEL. THEY RECOMMENDED DEPLANING ACFT ON TXWY. MAIN CABIN DOOR WAS USED TO EXIT ONTO PORTABLE STAIRS. CAPT AND FO PERFORMED EMER SHUTDOWN OF APU AND R ENG DUE TO PRESENCE OF LEAKING FUEL. NO INJURIES, NO DEPLOYMENT OF SLIDES. PAX BUSSED TO TERMINAL. ACFT TOWED TO GATE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: CAPT RPTS THE CREW FLEW THE ACFT THE DAY BEFORE. THEY WERE UNABLE TO START THE ENG BECAUSE OF A SHEARED STARTER SHAFT. AFTER THIS WAS REPAIRED, THEY WERE ABLE TO START THE ENG BUT THE GENERATOR WOULD NOT COME ON LINE BECAUSE OF A LOW N2 RPM. THE CAPT FEELS THAT THE N2 STAGE WAS BINDING AND CAUSED THE 2 PROBS. ON THE NEXT TRIP SEQUENCE THE FO DESCRIBED THE SYMPTOMS EXACTLY AND SAID HE HAD THE SAME THING HAPPEN THE YR BEFORE. THE ACFT USES THE ROLLS ROYCE TAY ENG. SUPPLEMENTAL INFO FROM ACN 456750: DURING INITIAL CLBOUT, #1 ENG EPR AND TGT BEGAN TO FLUCTUATE. SHORTLY THEREAFTER, WE RECEIVED SEVERAL 'TRANSIENT' ENG FAILURE #1 ALERTS ON MFDU SCREEN, BUT EACH ALERT APPEARED ONLY MOMENTARILY. DECISION WAS MADE TO RETURN TO MCO WITH THE #1 ENG STILL OPERATING. AT APPROX 400 FT AGL ON APCH, ENG #1 FAILED. CHKLIST ITEMS WERE ACCOMPLISHED AND PAX WERE DEPLANED VIA AIRSTAIRS AFTER CLRING RWY.
