## Discrepancy

CLT-PIT - FLT 1230 - AFTER TAKEOF AND THE LANDING GEAR WAS RETRACTED, THERE WAS A NOISE IN THE NOSE GEAR WELL.  A VIBRATION THEN OCCURRED.  WHEN THE LANDING GEAR WAS LOWERED TO RETURN TO THE FIELD THE VIBRATION CEASED.  THERE WERE NO ABNORMAL INDICATIONS.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE REMOVED AND REPLACED THE RIGHT NOSE LANDING GEAR DOOR LINK ASSY.  ADJUSTED RIGHT NOSE LANDING GEAR DOOR.  JACKED AND SWUNG NOSE GEAR PER MM 32-30-0.  OPERATIONAL CHECK GOOD.  (M)
