TAIL STRIKE ON TKOF OF 727.

Narrative

COPLT WAS MAKING THE TKOF. ACFT WAS MARGINAL AVERAGE WT OF 160000 LBS; ROTATE SPD ABOUT 155 KTS. WX WAS NOT A FACTOR; WINDS WERE LIGHT. COPLT'S ROTATION WAS A LITTLE QUICK; BUT NOT OVERLY SO. I WAS WATCHING OUTSIDE LINE-UP WHEN ROTATION COMMENCED. AS THE NOSE POPPED UP QUICKER THAN I EXPECTED; I LOOKED INSIDE AT GYROSCOPE. WE WERE PASSING 10 DEGS NOSE-UP AS THE MAINS STARTED TO BREAK GND. HIS ROTATION GOT US STRAIGHT TO ABOUT 13 DEGS NOSE- UP. I DIDN'T FEEL OR HEAR ANYTHING; NOR DID TWR SAY ANYTHING TO US; SO WE CONTINUED A NORMAL DEP. 1/2 HR INTO THE FLT (OVER PMN) WE RECEIVED A DISPATCH ACARS MESSAGE ASKING ABOUT A TAIL STRIKE ON DEP. ALL 3 OF US IN THE COCKPIT FELT NOTHING; HOWEVER; I INTERPHONED THE AFT FLT ATTENDANT. SHE SAID SHE HEARD A SMALL SCRAPE. WE RADIOED DISPATCH AND HE AND I CONCURRED TO HAVE IT INSPECTED ON ARR DEN. AT DEN; TAILSKID SHOWED NO SIGNS OF A STRIKE. THE CLIP WAS STILL INTACT; AS WAS ALL THE GREASE ON THE SKID. I DISCUSSED ROTATIONS AND TARGET PITCH WITH MY COPLT FOR HIS FUTURE CONSIDERATIONS. I MYSELF WILL PAY MORE INSIDE ATTN; ESPECIALLY WITH NEWER COPLTS. UNTIL RECENTLY MOST FLYING HAS BEEN WITH MORE EXPERIENCED COPLTS SO MY VIGILANCE HAS BEEN DIFFERENT.
