FAN BLADE DAMAGE MANDATES A RETURN LAND AFTER A SERIES OF COMPRESSOR STALLS ON THE L ENG OF AN MD80 DURING TKOF AND CLB FROM ZZZ.

Narrative

DURING TKOF ROLL; THE L ENG COMPRESSOR STALLED ONCE AT APPROX V1. THE EPR ROLLED BACK SLIGHTLY; RECOVERED AND ALL OTHER PARAMETERS LOOKED NORMAL THE ROTATION WAS NORMAL; TURN TO THE E AND LEVELOFF AT 5000 FT WERE NORMAL. ONE OF THE FLT ATTENDANTS CALLED TO MAKE SURE WE WERE AWARE OF THE ENG NOISE THAT HAD OCCURRED ON THE RWY. WE WERE CLRED TO 13000 FT AND WE BOTH WATCHED THE ENGS CAREFULLY TO MAKE SURE THEY ACCELERATED NORMALLY AS WE STARTED THE CLB. ALL INDICATIONS ON BOTH ENGS LOOKED GOOD. AS WE PASSED 10000 FT; WE RECEIVED A CLRNC TO FL230. AS I BEGAN TO ACCELERATE FOR THE CLB ABOVE 10000 FT; THE L ENG STALLED SEVERAL TIMES IN SUCCESSION. I DISCONNECTED THE AUTOTHROTTLES AND PULLED THE L ENG TO IDLE. WE ACCOMPLISHED THE ENG COMPRESSOR STALL CHKLIST AND RETURNED TO LAND AT ZZZ; EXACTLY AS WE HAD BRIEFED BEFORE LEAVING THE GATE. WE MADE AN UNEVENTFUL LNDG WITH THE ENG AT IDLE; CLRED THE RWY; AND TERMINATED THE EMER. AFTER PAX HAD DEPLANED; I BRIEFED MAINT AND COMPLETED THE LOG ENTRY. THE MAINT MAN GUESSED; BASED ON THE INFO I HAD GIVEN HIM; THAT THE ENG HAD A BLEED PROB. AFTER INSPECTION; HOWEVER; HE DISCOVERED BLADE DAMAGE AT THE ENG INLET. HE SUGGESTED THAT WE HAD TAKEN A CHUNK OF ICE IN DURING THE TKOF ROLL. THE RTE TO THE RWY WAS CLR AND THE RWY WAS CLR. THE ACFT WAS CLEAN AND THE GATE AREA WAS CLR. I THINK IF THE ENG WAS DAMAGED BY ICE INGESTION THAT THE DAMAGE OCCURRED BEFORE THIS FLT. SUPPLEMENTAL INFO FROM ACN 638496: WE TAXIED OUT USING ENG ANTI-ICE WITH A TEMP/DEWPOINT OF 1/-1 DEG. THE STALL CLRED WHEN THE L THROTTLE WAS RETARDED TO BELOW CLB THRUST; SO THE CAPT LEFT THE L ENG RUNNING AT A REDUCED PWR SETTING. WE PERFORMED THE ENG STALL; SINGLE ENG LNDG; AND BEFORE LNDG CHKLISTS. WERE CLRED THE ILS RWY XXL; NOTIFIED THE FLT ATTENDANTS AND PAX ABOUT THE SIT AND THAT WE WERE RETURNING TO ZZZ FOR A LNDG. TWR INFORMED US THAT CFR WAS IN PLACE AND CLRED US TO LAND. CAPT PERFORMED THE LNDG USING SINGLE ENG LNDG PROCS. I HAD NOTED NOTHING UNUSUAL ON THE PREFLT WALKAROUND; THE WINGS WERE CLEAN; AND WE SAW NO BIRDS ON TKOF.
