Narrative:

During 5 degree flap takeoff, and acting as first officer, PF which was myself inadvertently scraped the tailskid on a medium large transport during rotation. Post-flight inspection confirmed this, however indicator on tailskid was still in the normal position. In retrospect, I obviously over rotated slightly prior to becoming airborne. Although the rotation rate and attitude seemed normal to both flight crew members, it apparently was a little over zealous. New skid plate was placed on aircraft, and aircraft was then returned to service. I believe a contributing factor was the fact that this was only my third takeoff during line operations in the preceeding 4 weeks. First 5 degree flaps takeoff in last 4-5 weeks. Should have briefed possibility of over rotation during a 5 degree versus 15 degree flap takeoff. Also, should have made a more conscious effort to slow rotation, especially considering runway length, winds, and WX were all favorable. Supplemental information from acn 162038. Atl tower reported sparks were seen at rear of act at time of rotation. F/as did not state anything unusual about the takeoff until takeoff plus 45 mins when a F/a visited the cockpit offering beverages.

Title: ACR MLG TAIL STRIKE DURING TKOF.

Narrative: DURING 5 DEG FLAP TKOF, AND ACTING AS F/O, PF WHICH WAS MYSELF INADVERTENTLY SCRAPED THE TAILSKID ON A MLG DURING ROTATION. POST-FLT INSPECTION CONFIRMED THIS, HOWEVER INDICATOR ON TAILSKID WAS STILL IN THE NORMAL POS. IN RETROSPECT, I OBVIOUSLY OVER ROTATED SLIGHTLY PRIOR TO BECOMING AIRBORNE. ALTHOUGH THE ROTATION RATE AND ATTITUDE SEEMED NORMAL TO BOTH FLT CREW MEMBERS, IT APPARENTLY WAS A LITTLE OVER ZEALOUS. NEW SKID PLATE WAS PLACED ON ACFT, AND ACFT WAS THEN RETURNED TO SVC. I BELIEVE A CONTRIBUTING FACTOR WAS THE FACT THAT THIS WAS ONLY MY THIRD TKOF DURING LINE OPS IN THE PRECEEDING 4 WKS. FIRST 5 DEG FLAPS TKOF IN LAST 4-5 WKS. SHOULD HAVE BRIEFED POSSIBILITY OF OVER ROTATION DURING A 5 DEG VERSUS 15 DEG FLAP TKOF. ALSO, SHOULD HAVE MADE A MORE CONSCIOUS EFFORT TO SLOW ROTATION, ESPECIALLY CONSIDERING RWY LENGTH, WINDS, AND WX WERE ALL FAVORABLE. SUPPLEMENTAL INFO FROM ACN 162038. ATL TWR RPTED SPARKS WERE SEEN AT REAR OF ACT AT TIME OF ROTATION. F/AS DID NOT STATE ANYTHING UNUSUAL ABOUT THE TKOF UNTIL TKOF PLUS 45 MINS WHEN A F/A VISITED THE COCKPIT OFFERING BEVERAGES.
