Narrative:

On feb/sun/96 while departing mia at approximately XA10Z an LR25 suffered a bird strike on takeoff. A warning of birds on and about the center of the airport had been noted. On the takeoff roll on runway 27R a white egret type bird of medium size was observed flying across the runway from south to north at about 2-3 ft AGL, the bird did not come into view until after V1, no evasive action was possible due to the phase of the takeoff. The strike occurred post rotation but prior to lift-off, the speed at impact was approximately 135 KTS to 140 KTS. The bird must have impacted the spinning nosewheel/tire assembly. After impact the takeoff was continued to 1500 ft, the gear was left down as precautionary measure and takeoff flaps remained set. The tower was advised of the strike and a return to the airport was requested to inspect for damage. During the return to land a vibrating fluttering noise was noted seemingly originating from the underbelly in the area just under and aft of the pilot seat, however no adverse flight control problems were noted and a normal landing was made. Upon shutdown a visual inspection was conducted of the nose gear, doors and wheel well -- main gear, doors and wheel wells -- engine inlets and guide vanes -- leading edges of the wings and tail and the underside of the fuselage and all protruberences while in contact via cellular telephone with the company director of maintenance. Bird residue was found on the underbelly skin about 3 inches aft of and slightly left of center of the nose gear wheel well with no perforation or deformation of the skin noted. Additionally, bird debris (body parts) found entangled on the ADF sense antenna and removed as the suspect cause of the vibrating/fluttering noise noted after impact. After removing the bird debris from the antenna and finding all protruberences secure, the aircraft was determined to be safe for flight and was redispatched.

Title: AN ATX LEARJET HAS A BIRD STRIKE ON TKOF. RETURN LAND. NO DAMAGE.

Narrative: ON FEB/SUN/96 WHILE DEPARTING MIA AT APPROX XA10Z AN LR25 SUFFERED A BIRD STRIKE ON TKOF. A WARNING OF BIRDS ON AND ABOUT THE CTR OF THE ARPT HAD BEEN NOTED. ON THE TKOF ROLL ON RWY 27R A WHITE EGRET TYPE BIRD OF MEDIUM SIZE WAS OBSERVED FLYING ACROSS THE RWY FROM S TO N AT ABOUT 2-3 FT AGL, THE BIRD DID NOT COME INTO VIEW UNTIL AFTER V1, NO EVASIVE ACTION WAS POSSIBLE DUE TO THE PHASE OF THE TKOF. THE STRIKE OCCURRED POST ROTATION BUT PRIOR TO LIFT-OFF, THE SPD AT IMPACT WAS APPROX 135 KTS TO 140 KTS. THE BIRD MUST HAVE IMPACTED THE SPINNING NOSEWHEEL/TIRE ASSEMBLY. AFTER IMPACT THE TKOF WAS CONTINUED TO 1500 FT, THE GEAR WAS LEFT DOWN AS PRECAUTIONARY MEASURE AND TKOF FLAPS REMAINED SET. THE TWR WAS ADVISED OF THE STRIKE AND A RETURN TO THE ARPT WAS REQUESTED TO INSPECT FOR DAMAGE. DURING THE RETURN TO LAND A VIBRATING FLUTTERING NOISE WAS NOTED SEEMINGLY ORIGINATING FROM THE UNDERBELLY IN THE AREA JUST UNDER AND AFT OF THE PLT SEAT, HOWEVER NO ADVERSE FLT CTL PROBS WERE NOTED AND A NORMAL LNDG WAS MADE. UPON SHUTDOWN A VISUAL INSPECTION WAS CONDUCTED OF THE NOSE GEAR, DOORS AND WHEEL WELL -- MAIN GEAR, DOORS AND WHEEL WELLS -- ENG INLETS AND GUIDE VANES -- LEADING EDGES OF THE WINGS AND TAIL AND THE UNDERSIDE OF THE FUSELAGE AND ALL PROTRUBERENCES WHILE IN CONTACT VIA CELLULAR TELEPHONE WITH THE COMPANY DIRECTOR OF MAINT. BIRD RESIDUE WAS FOUND ON THE UNDERBELLY SKIN ABOUT 3 INCHES AFT OF AND SLIGHTLY L OF CTR OF THE NOSE GEAR WHEEL WELL WITH NO PERFORATION OR DEFORMATION OF THE SKIN NOTED. ADDITIONALLY, BIRD DEBRIS (BODY PARTS) FOUND ENTANGLED ON THE ADF SENSE ANTENNA AND REMOVED AS THE SUSPECT CAUSE OF THE VIBRATING/FLUTTERING NOISE NOTED AFTER IMPACT. AFTER REMOVING THE BIRD DEBRIS FROM THE ANTENNA AND FINDING ALL PROTRUBERENCES SECURE, THE ACFT WAS DETERMINED TO BE SAFE FOR FLT AND WAS REDISPATCHED.
