Narrative:

At takeoff from montreal runway 06R seagull flew by cockpit at vr, heard thud sound moments later, followed by vibration sound. No abnormal engine or aircraft indications, all normal. Continued takeoff and climb out. At about 10000 MSL, noticed high engine vibration readings about 4.0. Engine reading still normal reduced power on engine. Left running at reduced power for balance of flight to bos. Normal approach and landing. Upon engine inspection at bos, found 3 badly bent fan blades on the right engine. We elected to leave the engine running en route because WX was marginal at montreal. All engine readings were normal (N1, N2, egt, ff, oil pressure, oil temperature) short time to bos with good WX, equipment and maintenance.

Title: A BIRD STRIKE IN 1 ENG OF AN LGT ACR ACFT DAMAGED 3 OF THE ENG FAN BLADES CAUSING THE FLC TO REDUCE PWR TO THE ENG ABOVE 10000 FT.

Narrative: AT TKOF FROM MONTREAL RWY 06R SEAGULL FLEW BY COCKPIT AT VR, HEARD THUD SOUND MOMENTS LATER, FOLLOWED BY VIBRATION SOUND. NO ABNORMAL ENG OR ACFT INDICATIONS, ALL NORMAL. CONTINUED TKOF AND CLBOUT. AT ABOUT 10000 MSL, NOTICED HIGH ENG VIBRATION READINGS ABOUT 4.0. ENG READING STILL NORMAL REDUCED PWR ON ENG. LEFT RUNNING AT REDUCED PWR FOR BAL OF FLT TO BOS. NORMAL APCH AND LNDG. UPON ENG INSPECTION AT BOS, FOUND 3 BADLY BENT FAN BLADES ON THE R ENG. WE ELECTED TO LEAVE THE ENG RUNNING ENRTE BECAUSE WX WAS MARGINAL AT MONTREAL. ALL ENG READINGS WERE NORMAL (N1, N2, EGT, FF, OIL PRESSURE, OIL TEMP) SHORT TIME TO BOS WITH GOOD WX, EQUIP AND MAINT.
