MLG DEICED BUT HAS FOD; BOTH ENGS IN TKOF.

Narrative

PUSHED BACK FROM GATE IN BNA FOR DEICE. (OVERNIGHT ACFT HAD A HVY AMOUNT OF ICE ON ACFT.) TEMP 35 DEGS F - LIGHT RAIN. DEICE BEGAN AT XA09 CST. TOOK ABOUT 20 MINS. GND CREWMAN TOLD ME THE ACFT WAS FREE OF SNOW AND ICE AND THE WING TOPS WERE FREE TO MOVE. TYPE 1 FLUID APPLIED. CHK OUR POM AND THE ONLY GUIDANCE ABOVE -32 DEGS F IS FOR COLD-SOAKED FUEL WING ICE. OUR FUEL TEMP WAS 14 DEG L AND 15 DEGS R. DELAYED LOWERING FLAPS AND TAXIED SLOWLY BECAUSE RAMP HAD ABOUT 1 INCH OF SLUSH. ESTABLISHED ON PARALLEL FOR RWY 20L (TXWY WAS PLOWED) FO WENT BACK TO CHK ON WING AND INLETS. RPTED TO ME THAT WING AND ENG INLETS WERE CLEAN. FLAPS LOWERED AND TAXI AND TKOF CHKLIST WAS COMPLETED. ENG ANTI-ICE ON; FLAPS 11 DEGS TKOF 1/2 INCH CLUTTER WT SELECTED. RWY 20L WAS PRETTY CLEAN WITH AT MOST 1/8 INCH OF CLUTTER IN SPOTS. TOTAL TAXI TIME ABOUT 10 MINS. FO WAS FLYING ACFT. UPON SLAT RETRACTION AT ABOUT 180 KTS AND 1500 FT AGL; FELT A SMALL COMPRESSOR STALL FROM THE #1 ENG. ABOUT 2-3 SECONDS LATER #2 ENG SUFFERED A RATHER LARGE DOUBLE COMPRESSOR STALL. #2 EPR DROPPED TO 1.60 EPR. WITH A VIBRATION. I CHKED THAT THE ENG IGNITION WAS STILL ON 'BOTH' - (IT WAS) AND WHEN I LOOKED BACK AT #2 EPR IT WAS RECOVERING. PWR WAS REDUCED AND THE VIBRATION STOPPED. WITH NOW NORMAL ENG INDICATIONS I TOLD THE FO WE WERE GOING BACK TO BNA. NOTIFIED DEP CTL; FLT ATTENDANT AND PA TO THE PAX. RETURNED TO RWY 2L FOR ILS (CALM WINDS - BNA IN PROCESS OF TURNING ARPT AROUND. DSCNT; APCH; BEFORE LNDG DONE. NORMAL FLAPS 40 LNDG. ENG ANTI-ICE ON; WING ANTI-ICE OFF (NO AIRFRAME ICING). TAXI-IN WITH BOTH ENGS RUNNING. ENG INSTS NORMAL. AT GATE MECHS FOUND FAN BLADE DAMAGE TO BOTH ENGS. #2 ENG MORE SEVERE. DISCUSSED POSSIBILITY OF ICE THROWN UP FROM RWY OR A BIRD STRIKE. ALSO FOUND PATCH OF ICE ON R WING (ROOT AT TRAILING EDGE) ABOUT 1 INCH HIGH; 4 INCHES WIDE; 18 INCHES LONG. STATION MGR INSPECTED ICE ON WING AND FO AND I WENT UP TO CABIN AND WERE UNABLE TO SEE ICE AT MD-88 WING ROOT DUE TO THE CURVATURE OF THE FUSELAGE. SUSPECT GND CREW DID NOT REMOVE ALL OF THE ICE AT BOTH WING ROOTS AND ICE FOD INGESTED BY BOTH ENGS. IF GND DEICE CREW DOES NOT REMOVE ICE FROM WING ROOT AND FILLET; THE FLC IS UNABLE TO SEE THIS ICE FROM INSIDE OF CABIN DURING PRE-TKOF INSPECTION. A THOROUGH INSPECTION OF THE ACFT BY THE DEICING CREW HAS TO BE DONE TO PREVENT THIS FROM HAPPENING TO ANY ACFT MOUNTED ENG ACFT. IF THE DEICING IS DONE AWAY FROM THE GATE; THE DEICING CREW IS THE FINAL SAFETY NET FOR ICE IN THE WING ROOT. THIS WAS NOT A COLD-SOAKED WING FUEL ICING PROB; THIS WAS A FAILURE OF THE DEICING PROCESS.
