## Discrepancy

CLIMBING THROUGH FL300 AT APPROX .68M WITH AUTOPILOT ON, A SIGNIFICANT VIBRATION BEGAN IN BOTH CONTROL COLUMNS.  AUTOPILOT WAS DISCONNECTED & THE VIBRATION CONTINUED.  WE LEVELED OFF & SLOWED & THERE WAS NO CHANGE.  WE BEGAN A DESCENT & THE VIBRATION SUBSIDED UNTIL APPROX FL270.  IT CONTINUED & WAS FELT IN THE CONTROL COLUMN & RUDDER PEDALS UNTIL APPROX 8000FT & 230 KIAS.  FROM THERE TO LANDING ALL CONTROLS FELT NORMAL. THE FLIGHT ATTENDANT FELT THE VIBRATION IN THE FLOOR OF THE FWD CABIN.  A PILOT SITTING IN SEAT 12B NOTICED AN AIRFRAME VIBE.  ACCOMPLISHED VIBRATION DVI IAW WC 12-200-01.  NO DEFECTS NOTED AT THIS TIME.  FCF FOUND SATISFACTORY.
