A COMMERCIAL HIGH FIXED WING MDT DECLARED AN EMER AND DIVERTED DUE TO A THROWN THREAD ON THE R NOSE GEAR TIRE INCURRING DAMAGE TO THE FUSELAGE SKIN AFT OF THE NOSE GEAR.

Narrative

DURING THE TKOF RUN; A VIBRATION WAS NOTED FROM THE NOSEWHEEL ASSEMBLY. IT WAS VERY MUCH LIKE THAT PRODUCED BY WHEEL/TIRE OUT OF BAL OR A BAD WHEEL BEARING. AS THE ACFT WAS ROTATED FOR LIFTOFF; A VIOLENT VIBRATION ALONG WITH A LOUD BANGING NOISE WAS HEARD AND PIECES OF TIRE FLEW BY THE WINDSHIELD. DURING INITIAL CLB THE BANGING NOISE CONTINUED; SO THE LNDG GEAR WAS LEFT IN THE DOWN AND LOCKED POS. WE THEN PERFORMED A FLY-BY OF THE FIELD FOR CFR TO MAKE A VISUAL INSPECTION FOR DAMAGE. THEY RPTED NO OBVIOUS ACFT DAMAGE OTHER THAN A LONG FLAP OF RUBBER HANGING FROM THE R NOSE TIRE. WE PERFORMED A LNDG ON RWY 35 WITH A DRY SURFACE AND WINDS OF 060 DEGS AT 16 KTS. AT NOSEWHEEL TOUCHDOWN; CONSIDERABLE CTL INPUTS WERE NEEDED TO MAINTAIN DIRECTIONAL CTL UNTIL THE FLAPPING TIRE PIECE SEPARATED AND THEN DIRECTIONAL CTL RETURNED TO NORMAL. POSTFLT INSPECTION REVEALED THAT THE RETREAD HAD DELAMINATED FROM THE TIRE. THE TIRE CARCASS REMAINED INTACT AND INFLATED. SIGNIFICANT DAMAGE HAD BEEN DONE TO THE EXTERIOR SKIN AFT OF THE NOSE GEAR WELL.
