## Discrepancy

PILOT NOTICED NOISE AND VIBRATION EMMINATING FROM THE MAIN ROTOR SYSTEM BEGINNING 4 MINUTES INTO FLIGHT.  NOISE AND VIBRATION INCREASED WITH AIRSPEED.  PILOT ABORTED FLIGHT AND MADE A PRECAUTIONARY LANDING.  MECHANIC WAS DISPATCHED AND FOUND DEBONDING BLADE TAPE (PU FILM) ON THE CENTER SECTION OF 1 EA M/R BLADE.  OLD TAPE WAS COMPLETELY REMOVED AND AREA WAS CLEANED AND INSPECTED WITH NO DEFECTS NOTED.  NEW BLADE TAPE WAS APPLIED, AND THE ACFT WAS RETURNED TO SERVICE.
