## Discrepancy

UPON LIFTOFF FROM MGM, THE CAPTAIN OBSERVED A STRONG VIBRATION FOR ABOUT 15-20 SECONDS.  THE CAPTAIN DECLARED AN EMERGENCY AND RETURNED TO MGM FOR AN UNEVENTFUL LANDING.  MAINTENANCE INSPECTED THE DOORS, PANELS, DE-ICE BOOTS, AND LANDING GEAR AND FOUND NO DEFECTS.  THE LEFT INBOARD TIRE WAS DISCOVERED TO HAVE A TEN INCH FLAT SPOT.  MAINTENANCE REMOVED AND REPLACED THE FLAT SPOTTED LEFT TIRE.  (M)
