## Discrepancy

DURING CRUISE AT 24000 FT, NOTICED A LOUD NOISE ACCOMPANIED BY A CONTINOUS VIBRATION. DECELLERATED FROM 300 KTS TO 200KTS (APPROX).  NOISE DECREASED BUT DID NOT GO AWAY.

CHECKED NLG DOORS AND AREA IAW AMM 32-22-00, DOORS SEEM OK, NO DEFECTS NOTED IN NOSE GEAR AREA.   CHECK FLIGHT WAS SATISFACTORY. THE ACFT RETURNED TO SERVICE.
