A B737-300 #1 ENG FAILS ON A FERRY FLIGHT. ACFT PREVIOUSLY INSPECTED FOR BIRD STRIKE DAMAGE. MECHANIC RECOMMENDS DOING A TAKEOFF ENGINE POWER CHECK PRIOR TO SIGNING OFF THE BIRD STRIKE INSPECTION WALKAROUND.

Narrative

I RECEIVED A CALL FOR MAINT TO CHK ACFT FOR THRUST REVERSER DISCREPANCY. WHEN THE ACFT CAME TO THE GATE; I NOTICED THAT THE ACFT HAD EXPERIENCED A BIRD STRIKE ON THE L WING AND OUTBOARD SIDE OF #1 ENG. I WENT TO THE CAPT. HE TOLD ME HE ENCOUNTERED A BIRD STRIKE. HE TOLD ME THAT ALL ENG PARAMETERS WERE NORMAL AND NO SMELL ASSOCIATED WITH THE BIRD STRIKE. I PERFORMED AN ENG PARAMETERS NORMAL BIRD STRIKE INSPECTION -- BEFORE AND AFTER I CLEANED IT. I LOOKED OVER THE ENTIRE ACFT MANY TIMES. THE DAMAGE FOUND DENT OUTBOARD SIDE OF #1 ENG 9 O'CLOCK POS. DAMAGE TO INBOARD FORE-FLAP TRAILING EDGE. DAMAGE TO L INBOARD MID-FLAP LEADING EDGE. ALL DAMAGE WAS CONTAINED ON L SIDE OF ACFT. I ENTERED ALL WRITE-UPS IN LOGBOOK AND INSPECTED ACFT FOR 1-TIME FERRY FLT. THE NEXT DAY THE ACFT LOST #1 ENG. I THINK; IN THE FUTURE; ALL BIRD STRIKES WITH DEBRIS IN THE BYPASS AREA SHOULD UNDERGO A TKOF PWR CHK PRIOR TO SIGNING OFF INSPECTION. I HAVE INSPECTED QUITE A FEW ENGS SINCE COMING TO THIS LOCATION AND EVERY ONE I'VE INSPECTED IS STILL FLYING. SO TO MAKE SURE THIS DOES NOT HAPPEN; I RECOMMEND DOING RUN-UP OF ACFT.
