Narrative:

During takeoff roll on runway 16R, just prior to V1 (105 KTS), I observed a single bird crossing the runway from left to right in flight approximately a ft off the pavement. It was immediately evident that unless the bird did an immediate 180 reversal, he would pass directly under the aircraft. Instead, the bird climbed vertical, passing within a few ft of the pilot side window. The bird was ingested into the left engine. The takeoff was aborted at V1. The abort was normal, no antiskid was required or used. Reverse thrust was used from both engines as the engine was still producing usable power. Inlet turbine temperature (itt) readout was lost, therefore, upon clearing the runway, the engine was shut down. A visual inspection revealed severe damage to the compressor fan. Apparently, the bird struck the 'T1' probe, severing the probe. The bird and probe were ingested into the compressor fan. Several large chunks of the fan blades separated, thereby causing considerable more damage. Most of the 'debris' exited out the bypass duct, although there is evidence (upon teardown) of minor damage of the impeller and the hot section indicating that some pieces exited through the engine core. The estimated down time is 30 to 40 days and the cost to repair is already at 145000 dollars and will probably top 165000 dollars!! Notes: this is a covered loss to the insurance company, but better bird management at airports could save a lot of money -- maybe lives. There was another bird strike at the same airport that day! After inspecting the fan damage, the manufacturer's engine representative asked me if I happened to see if the bird was carrying a 'snap-on crescent wrench??!!' the bird has not yet been idented (nor next of kin told) but local airport authorities believe it to be a sparrowhawk

Title: BIRD STRIKE ON TKOF. FOREIGN OBJECT DAMAGE REQUIRES PLT TO ABORT TKOF. FOREIGN OBJECT INGESTION BIRD.

Narrative: DURING TKOF ROLL ON RWY 16R, JUST PRIOR TO V1 (105 KTS), I OBSERVED A SINGLE BIRD XING THE RWY FROM L TO R IN FLT APPROX A FT OFF THE PAVEMENT. IT WAS IMMEDIATELY EVIDENT THAT UNLESS THE BIRD DID AN IMMEDIATE 180 REVERSAL, HE WOULD PASS DIRECTLY UNDER THE ACFT. INSTEAD, THE BIRD CLBED VERT, PASSING WITHIN A FEW FT OF THE PLT SIDE WINDOW. THE BIRD WAS INGESTED INTO THE L ENG. THE TKOF WAS ABORTED AT V1. THE ABORT WAS NORMAL, NO ANTISKID WAS REQUIRED OR USED. REVERSE THRUST WAS USED FROM BOTH ENGS AS THE ENG WAS STILL PRODUCING USABLE PWR. INLET TURBINE TEMP (ITT) READOUT WAS LOST, THEREFORE, UPON CLRING THE RWY, THE ENG WAS SHUT DOWN. A VISUAL INSPECTION REVEALED SEVERE DAMAGE TO THE COMPRESSOR FAN. APPARENTLY, THE BIRD STRUCK THE 'T1' PROBE, SEVERING THE PROBE. THE BIRD AND PROBE WERE INGESTED INTO THE COMPRESSOR FAN. SEVERAL LARGE CHUNKS OF THE FAN BLADES SEPARATED, THEREBY CAUSING CONSIDERABLE MORE DAMAGE. MOST OF THE 'DEBRIS' EXITED OUT THE BYPASS DUCT, ALTHOUGH THERE IS EVIDENCE (UPON TEARDOWN) OF MINOR DAMAGE OF THE IMPELLER AND THE HOT SECTION INDICATING THAT SOME PIECES EXITED THROUGH THE ENG CORE. THE ESTIMATED DOWN TIME IS 30 TO 40 DAYS AND THE COST TO REPAIR IS ALREADY AT 145000 DOLLARS AND WILL PROBABLY TOP 165000 DOLLARS!! NOTES: THIS IS A COVERED LOSS TO THE INSURANCE COMPANY, BUT BETTER BIRD MGMNT AT ARPTS COULD SAVE A LOT OF MONEY -- MAYBE LIVES. THERE WAS ANOTHER BIRD STRIKE AT THE SAME ARPT THAT DAY! AFTER INSPECTING THE FAN DAMAGE, THE MANUFACTURER'S ENG REPRESENTATIVE ASKED ME IF I HAPPENED TO SEE IF THE BIRD WAS CARRYING A 'SNAP-ON CRESCENT WRENCH??!!' THE BIRD HAS NOT YET BEEN IDENTED (NOR NEXT OF KIN TOLD) BUT LCL ARPT AUTHORITIES BELIEVE IT TO BE A SPARROWHAWK
