MECHANIC FOUND TAIL SKID DAMAGE ON ACR LGT PARKED AT GATE.

Narrative

THIS WAS THE ONLY LEG MY CREW FLEW ACFT. AFTER ARR AT TUL; MAINT INFORMED ME THAT DAMAGE TO THE TAIL SKID AND AFT AIRSTAIR VENTRAL HAD BEEN DISCOVERED DURING A SUBSEQUENT PREFLT. I WAS QUESTIONED WHETHER MY ACTIONS OR THE ACTIONS OF MY CREW ON FLT COULD HAVE RESULTED IN THE SUBJECT DAMAGE. MY F/O FLEW THE SEGMENT FROM ORD TO TUL. DURING THIS FLT I OBSERVED NO IRREGULARITIES OR ABNORMALITIES. BOTH THE TKOF ROTATION AND LNDG FLARE WERE OBSERVED TO BE NORMAL AND DID NOT ACHIEVE EXCESSIVE DECK ANGLE. THE S/O STATED HE CONDUCTED A ROUTINE STANDARD PREFLT AT ORD AND DID NOT NOTICE ANY ACFT DAMAGE. THE CAUSE OF THE SUBJECT DAMAGE IS UNKNOWN. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: DAMAGE WAS PROBABLY NOT DONE ON THIS TRIP AS AFT CABIN ATTENDANT FELT NOTHING AND USUALLY THEY ARE THE FIRST TO KNOW TAIL STRIKE IN THIS MODEL LGT. APPEARS THE COVER PLATE OVER THE TAIL SKID SPLIT AND FLEW BACK AND CAUSED THE DAMAGE TO VENTRAL STAIR. RPTR ALMOST CERTAIN THEY DID NOT DRAG; BASED ON ATTITUDE AT T/D. HIS FLT MGR IS SATISFIED NOT THIS FLT CREW'S FAULT AND FEELS THEY ARE VICTIMS.
