Narrative:
We departed runway 21L at dtw for rsw. At or about 130 KTS, we felt a very slight vibration, nothing out of the ordinary. All departure checks were normal and en route indications were normal. Upon landing at rsw while talking to ground approaching the gate area, ground stated that we had smoke coming from the right tire area. We parked the aircraft and at postflt examination found the #3 inboard right main tire tread cap had separated from the tire. We also observed a hole in the trailing edge of the flap. A rare mechanical failure. Callback conversation with reporter revealed the following information: the reporter stated the aircraft was a DC9-30 and the preflight check gave no indication of the problems or thread separation. The reporter said the damage to the trailing edge flap was an 8 inch diameter hole through the flap. The reporter stated the number of the recap was unknown.

Title: A DC9-30 ON TKOF ROLL EXPERIENCED A THROWN THREAD ON #3 MAIN TIRE INCURRING DAMAGE TO THE TRAILING EDGE FLAP.
Narrative: WE DEPARTED RWY 21L AT DTW FOR RSW. AT OR ABOUT 130 KTS, WE FELT A VERY SLIGHT VIBRATION, NOTHING OUT OF THE ORDINARY. ALL DEP CHKS WERE NORMAL AND ENRTE INDICATIONS WERE NORMAL. UPON LNDG AT RSW WHILE TALKING TO GND APCHING THE GATE AREA, GND STATED THAT WE HAD SMOKE COMING FROM THE R TIRE AREA. WE PARKED THE ACFT AND AT POSTFLT EXAM FOUND THE #3 INBOARD R MAIN TIRE TREAD CAP HAD SEPARATED FROM THE TIRE. WE ALSO OBSERVED A HOLE IN THE TRAILING EDGE OF THE FLAP. A RARE MECHANICAL FAILURE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE ACFT WAS A DC9-30 AND THE PREFLT CHK GAVE NO INDICATION OF THE PROBS OR THREAD SEPARATION. THE RPTR SAID THE DAMAGE TO THE TRAILING EDGE FLAP WAS AN 8 INCH DIAMETER HOLE THROUGH THE FLAP. THE RPTR STATED THE NUMBER OF THE RECAP WAS UNKNOWN.
