Narrative:

Aircraft sustained multiple bird strikes on takeoff roll on runway 22 at evv. Speed at time of impact was approximately 120-125 KIAS, and reduced V1 was 123. The birds were part of a flock of 20-30 small birds flying from right to left, and they appeared to strike mostly on the right side of the aircraft. There were several rapid impact sounds, and a momentary slight hesitation in the acceleration of the aircraft. Both sets of engine instruments appeared normal throughout the flight. A strong 'burning bird' smell began immediately, and lasted 5-10 mins. On climb out, we advised evv tower of the bird strikes. I seriously considered returning to land at evv to check for possible damage, but elected to continue to ind only because there was no indication first officer any engine problem whatsoever on the gauges. Flight to ind was uneventful, and while en route ARTCC relayed a message to us from evv approach control that approximately 2 dozen birds/bird parts had been found on the runway. Upon arrival at ind, we inspected the aircraft and found 3 or 4 bird strike marks in the #2 engine, 2 or 3 marks in the #1 engine, and several other marks on the fuselage and wings. There was no visible damage to the #2 engine, but the #1 engine had 3 damaged blades, including 1 missing piece (1/2 inch X 1 inch long) at the outer edge of a blade, and a small nick in another blade. It was determined that the #1 engine would have to be changed, after completing the internal inspection. I have saved a sample of the bird feathers which I can send to any interested agency. Comments: the only thing I can think of to have avoided this problem would be if an airport vehicle had preceded us down the runway to attempt to flush out the flock of birds, but I realize that it's probably something that will continue to be a problem to the aviation industry.

Title: ACR HAS MULTIPLE BIRD STRIKES ON TKOF ROLL.

Narrative: ACFT SUSTAINED MULTIPLE BIRD STRIKES ON TKOF ROLL ON RWY 22 AT EVV. SPD AT TIME OF IMPACT WAS APPROX 120-125 KIAS, AND REDUCED V1 WAS 123. THE BIRDS WERE PART OF A FLOCK OF 20-30 SMALL BIRDS FLYING FROM R TO L, AND THEY APPEARED TO STRIKE MOSTLY ON THE R SIDE OF THE ACFT. THERE WERE SEVERAL RAPID IMPACT SOUNDS, AND A MOMENTARY SLIGHT HESITATION IN THE ACCELERATION OF THE ACFT. BOTH SETS OF ENG INSTS APPEARED NORMAL THROUGHOUT THE FLT. A STRONG 'BURNING BIRD' SMELL BEGAN IMMEDIATELY, AND LASTED 5-10 MINS. ON CLBOUT, WE ADVISED EVV TWR OF THE BIRD STRIKES. I SERIOUSLY CONSIDERED RETURNING TO LAND AT EVV TO CHK FOR POSSIBLE DAMAGE, BUT ELECTED TO CONTINUE TO IND ONLY BECAUSE THERE WAS NO INDICATION FO ANY ENG PROBLEM WHATSOEVER ON THE GAUGES. FLT TO IND WAS UNEVENTFUL, AND WHILE ENRTE ARTCC RELAYED A MESSAGE TO US FROM EVV APCH CTL THAT APPROX 2 DOZEN BIRDS/BIRD PARTS HAD BEEN FOUND ON THE RWY. UPON ARR AT IND, WE INSPECTED THE ACFT AND FOUND 3 OR 4 BIRD STRIKE MARKS IN THE #2 ENG, 2 OR 3 MARKS IN THE #1 ENG, AND SEVERAL OTHER MARKS ON THE FUSELAGE AND WINGS. THERE WAS NO VISIBLE DAMAGE TO THE #2 ENG, BUT THE #1 ENG HAD 3 DAMAGED BLADES, INCLUDING 1 MISSING PIECE (1/2 INCH X 1 INCH LONG) AT THE OUTER EDGE OF A BLADE, AND A SMALL NICK IN ANOTHER BLADE. IT WAS DETERMINED THAT THE #1 ENG WOULD HAVE TO BE CHANGED, AFTER COMPLETING THE INTERNAL INSPECTION. I HAVE SAVED A SAMPLE OF THE BIRD FEATHERS WHICH I CAN SEND TO ANY INTERESTED AGENCY. COMMENTS: THE ONLY THING I CAN THINK OF TO HAVE AVOIDED THIS PROBLEM WOULD BE IF AN ARPT VEHICLE HAD PRECEDED US DOWN THE RWY TO ATTEMPT TO FLUSH OUT THE FLOCK OF BIRDS, BUT I REALIZE THAT IT'S PROBABLY SOMETHING THAT WILL CONTINUE TO BE A PROBLEM TO THE AVIATION INDUSTRY.
