Narrative:

Upon aircraft post inspection, noticed small lacerations on front of #3 tire. On takeoff, noticed rudder pedal vibration approximately 1/3 into takeoff roll. Takeoff was from runway 25R las. Overrun was used for takeoff. In peripheral vision at brake release, noticed a couple of open items on mechanical checklist. Did quick visual verification to ensure items were complete. Remembered performing and completing the checklist. 80 KT speed check missed. I made 100 KT call, looked up, and aligned with runway. Remember distinctly thinking overrun area was darker than normal. About 1/3 into takeoff roll, noticed slight vibration of rudder pedals not that much different than some other runways used in the system. No comments made by flight attendants or passenger or tower about anything unusual. It is possible that aircraft drifted right and hit runway edge lights before liftoff. Verified all aircraft system were normal shortly after takeoff and proceeded to destination. Possible contributing factors: pilot fatigue, poor visibility in takeoff overrun, last second initial takeoff pilot distraction for a couple of seconds. Cognizant of seriousness of distrs. Discussed at length with first officer to prevent such a chain of actions in the future. Supplemental information from acn 473356: during postflt in cos, noted damage to #3 tire, right main. Captain wrote up tire condition in logbook. Began to wonder how tire may have been damaged. Concluded circumstances during takeoff roll in las may have been suspect. In las, tower cleared us for takeoff on runway 25R and we had just completed right engine start, so last 5 or 6 items remained on mechanical checklist when we received takeoff clearance. Fairly rushed completion of checklist. Captain made entry onto runway and he set 1.4 EPR and then asked for autothrottles. I complied and then observed engine instruments wind up. It was fairly warm in las, so I carefully monitored egt's as the left engine slowly crept higher. I missed the 80 KT callout as a result and captain called 100 KTS. I recall fairly dark overrun area, but nothing exceptional during takeoff. Remainder of flight uneventful. Suspect tire damage may have taken place during takeoff in las from overrun surface or other FOD. I realize that 100% of both pilots' attention should have been outside cockpit during line-up and we should have requested a short delay to complete checklists. Fatigue coupled with delays throughout the day and a very quick turn in las also may have been a factor.

Title: ACR CREW DISCOVERS TIRE DAMAGE AT POSTFLT INSPECTION. THEY SUSPECT CONTACT WITH LIGHTS DURING THE TKOF AT LAS.

Narrative: UPON ACFT POST INSPECTION, NOTICED SMALL LACERATIONS ON FRONT OF #3 TIRE. ON TKOF, NOTICED RUDDER PEDAL VIBRATION APPROX 1/3 INTO TKOF ROLL. TKOF WAS FROM RWY 25R LAS. OVERRUN WAS USED FOR TKOF. IN PERIPHERAL VISION AT BRAKE RELEASE, NOTICED A COUPLE OF OPEN ITEMS ON MECHANICAL CHKLIST. DID QUICK VISUAL VERIFICATION TO ENSURE ITEMS WERE COMPLETE. REMEMBERED PERFORMING AND COMPLETING THE CHKLIST. 80 KT SPD CHK MISSED. I MADE 100 KT CALL, LOOKED UP, AND ALIGNED WITH RWY. REMEMBER DISTINCTLY THINKING OVERRUN AREA WAS DARKER THAN NORMAL. ABOUT 1/3 INTO TKOF ROLL, NOTICED SLIGHT VIBRATION OF RUDDER PEDALS NOT THAT MUCH DIFFERENT THAN SOME OTHER RWYS USED IN THE SYS. NO COMMENTS MADE BY FLT ATTENDANTS OR PAX OR TWR ABOUT ANYTHING UNUSUAL. IT IS POSSIBLE THAT ACFT DRIFTED R AND HIT RWY EDGE LIGHTS BEFORE LIFTOFF. VERIFIED ALL ACFT SYS WERE NORMAL SHORTLY AFTER TKOF AND PROCEEDED TO DEST. POSSIBLE CONTRIBUTING FACTORS: PLT FATIGUE, POOR VISIBILITY IN TKOF OVERRUN, LAST SECOND INITIAL TKOF PLT DISTR FOR A COUPLE OF SECONDS. COGNIZANT OF SERIOUSNESS OF DISTRS. DISCUSSED AT LENGTH WITH FO TO PREVENT SUCH A CHAIN OF ACTIONS IN THE FUTURE. SUPPLEMENTAL INFO FROM ACN 473356: DURING POSTFLT IN COS, NOTED DAMAGE TO #3 TIRE, R MAIN. CAPT WROTE UP TIRE CONDITION IN LOGBOOK. BEGAN TO WONDER HOW TIRE MAY HAVE BEEN DAMAGED. CONCLUDED CIRCUMSTANCES DURING TKOF ROLL IN LAS MAY HAVE BEEN SUSPECT. IN LAS, TWR CLRED US FOR TKOF ON RWY 25R AND WE HAD JUST COMPLETED R ENG START, SO LAST 5 OR 6 ITEMS REMAINED ON MECHANICAL CHKLIST WHEN WE RECEIVED TKOF CLRNC. FAIRLY RUSHED COMPLETION OF CHKLIST. CAPT MADE ENTRY ONTO RWY AND HE SET 1.4 EPR AND THEN ASKED FOR AUTOTHROTTLES. I COMPLIED AND THEN OBSERVED ENG INSTS WIND UP. IT WAS FAIRLY WARM IN LAS, SO I CAREFULLY MONITORED EGT'S AS THE L ENG SLOWLY CREPT HIGHER. I MISSED THE 80 KT CALLOUT AS A RESULT AND CAPT CALLED 100 KTS. I RECALL FAIRLY DARK OVERRUN AREA, BUT NOTHING EXCEPTIONAL DURING TKOF. REMAINDER OF FLT UNEVENTFUL. SUSPECT TIRE DAMAGE MAY HAVE TAKEN PLACE DURING TKOF IN LAS FROM OVERRUN SURFACE OR OTHER FOD. I REALIZE THAT 100% OF BOTH PLTS' ATTN SHOULD HAVE BEEN OUTSIDE COCKPIT DURING LINE-UP AND WE SHOULD HAVE REQUESTED A SHORT DELAY TO COMPLETE CHKLISTS. FATIGUE COUPLED WITH DELAYS THROUGHOUT THE DAY AND A VERY QUICK TURN IN LAS ALSO MAY HAVE BEEN A FACTOR.
