## Discrepancy

AFTER TAKEOFF AT APPROX 6000 FT, FLIGHT CREW NOTICED AN INTERMITTENT THUMP OCCURRING, FELT MOSTLY IN THE FLOORBOARDS.  FLIGHT ATTENDANT REPORTS THE NOISE WAS PRESENT SOONER THAN FLIGHT CREW NOTICED IT.  MOST NOTICEABLE IN FWD CABIN AREA.  NO ABNORMAL INDICATIONS OR FEEL IN FLIGHT CONTROLS, ENGS, APU OR PRESSURIZATION.  RETURNED & NOISE CONTINUED UNTIL LANDING.
