Narrative:

During takeoff at vr, 143 KTS, we began rotation, felt a vibration followed by a bang. Aircraft became airborne normally, flight controls and engines normal. Right main gear green down lock light was out, red 'gear unsafe' light on. We did not attempt to retract gear, went to departure control, leveled off at 4000 ft and began a vector for an extended pattern back to the airport. We performed all abnormal procedures including viewing the landing gear through viewing port in cabin floor. Gear indicated locked down, the tires could not be observed, however, wire conduits could be seen broken, gear doors appeared normal. Tower confirmed the remains of #1 tire were found on the runway. Flight attendants were briefed and passenger also for emergency landing. Landing was uneventful. #3 tire had blown and stripped off rubber. #4 tire was in good shape. Wiring to gear switch was gone and a hole in flap approximately 12 inches on trailing edge. No apparent engine FOD ingestion was noted. Crew performance was excellent. Coordination and communications between cockpit, cabin crew, and passenger was maintained. Good CRM.

Narrative: DURING TKOF AT VR, 143 KTS, WE BEGAN ROTATION, FELT A VIBRATION FOLLOWED BY A BANG. ACFT BECAME AIRBORNE NORMALLY, FLT CTLS AND ENGS NORMAL. R MAIN GEAR GREEN DOWN LOCK LIGHT WAS OUT, RED 'GEAR UNSAFE' LIGHT ON. WE DID NOT ATTEMPT TO RETRACT GEAR, WENT TO DEP CTL, LEVELED OFF AT 4000 FT AND BEGAN A VECTOR FOR AN EXTENDED PATTERN BACK TO THE ARPT.

GEAR INDICATED LOCKED DOWN, THE TIRES COULD NOT BE OBSERVED, HOWEVER, WIRE CONDUITS COULD BE SEEN BROKEN, GEAR DOORS APPEARED NORMAL. TWR CONFIRMED THE REMAINS OF #1 TIRE WERE FOUND ON THE RWY. FLT ATTENDANTS WERE BRIEFED AND PAX ALSO FOR EMER LNDG. LNDG WAS UNEVENTFUL. #3 TIRE HAD BLOWN AND STRIPPED OFF RUBBER. #4 TIRE WAS IN GOOD SHAPE. WIRING TO GEAR SWITCH WAS GONE AND A HOLE IN FLAP APPROX 12 INCHES ON TRAILING EDGE. NO APPARENT ENG FOD INGESTION WAS NOTED. CREW PERFORMANCE WAS EXCELLENT.
