Narrative:

I was giving a captain IOE from the right seat to a new captain who was flying from the left seat. We had just broken ground from runway 19 at msy (new orleans) when several birds (seagulls?) flashed by both sides of the cockpit followed immediately by a series of loud compressor stalls from #2 engine. As we gained altitude and airspeed, we slowly pulled back the throttle on #2 engine until it stabilized at idle. Since the engine was no longer compressor stalling, and all other indications were normal, we elected to leave it running at idle. We made an uneventful return to msy runway 10 and also elected to make a 15 degree flap landing which is our procedure for an engine out approach. At the gate, we, along with contract maintenance, inspected the #2 engine. While there was no apparent bird residue, 5 of the fan blades were bent forward at the leading edge corner about 2-3 inches in from the tip.

Original NASA ASRS Text

Title: B737 HITS SEVERAL BIRDS ON ROTATION FROM THE RWY AT MSY. ENG PWR PULLED BACK TO IDLE AFTER COMPRESSOR STALLS NOTED AT REGULAR PWR. RETURN TO MSY TO FIND BENT OR DAMAGED FIRST STAGE COMPRESSOR BLADES.

Narrative: I WAS GIVING A CAPT IOE FROM THE R SEAT TO A NEW CAPT WHO WAS FLYING FROM THE L SEAT. WE HAD JUST BROKEN GND FROM RWY 19 AT MSY (NEW ORLEANS) WHEN SEVERAL BIRDS (SEAGULLS?) FLASHED BY BOTH SIDES OF THE COCKPIT FOLLOWED IMMEDIATELY BY A SERIES OF LOUD COMPRESSOR STALLS FROM #2 ENG. AS WE GAINED ALT AND AIRSPD, WE SLOWLY PULLED BACK THE THROTTLE ON #2 ENG UNTIL IT STABILIZED AT IDLE. SINCE THE ENG WAS NO LONGER COMPRESSOR STALLING, AND ALL OTHER INDICATIONS WERE NORMAL, WE ELECTED TO LEAVE IT RUNNING AT IDLE. WE MADE AN UNEVENTFUL RETURN TO MSY RWY 10 AND ALSO ELECTED TO MAKE A 15 DEG FLAP LNDG WHICH IS OUR PROC FOR AN ENG OUT APCH. AT THE GATE, WE, ALONG WITH CONTRACT MAINT, INSPECTED THE #2 ENG. WHILE THERE WAS NO APPARENT BIRD RESIDUE, 5 OF THE FAN BLADES WERE BENT FORWARD AT THE LEADING EDGE CORNER ABOUT 2-3 INCHES IN FROM THE TIP.
