## Discrepancy

ON APPROACH, THE ACFT STARTED TO EXPERIENCE ABNORMAL VIBRATIONS. WHEN VIBRATION STARTED THE AUTO PILOT WAS DISENGAGED AND THE ACFT WAS FLOWN MANUALLY.  AS THE ACFT DESCENDED AND SLOWED DOWN, THE VIBRATION ALSO DECREASED. WHEN VIBRATION STARTED, THE F/A REPORTED A LOUD NOISE AND VIBRATION COULD BE FELT AFT OF THE WINGS.  LANDING WAS UNEVENTFUL, AND NO PHYSICAL DAMAGE WAS EVIDENT ON THE ACFT.  MX INSPECTED ENTIRE ACFT.  MX FOUND WING TO FUSELAGE FAIRING (295DL) IMPROPERLY INSTALLED.   REMOVED FAIRING AND REINSTALLED CORRECTLY. ACFT RELEASED FOR FUNCTIONAL CHECK FLIGHT.  FLIGHT CHECK SATISFACTORY.  ACFT RELEASED BACK TO SERVICE.
