## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

NARRATIVE: DURING DEPARTURE OUT OF IAD, WITH THE AIRCRAFT LEVEL AT 16,000 MSL, THE FLIGHT ATTENDANT REPORTED A VIBRATION IN THE FLOOR BETWEEN SEATS 8 AND 10. THE FIRST OFFICER VERIFIED THE VIBRATION AND REPORTED TO THE CAPTAIN THAT IT WAS VERY PROMINENT AND SEVERE. AN EMERGENCY WAS DECLARED AND THE AIRCRAFT RETURNED TO IAD. DURING DESCENT, THE AIRCRAFT SHOOK AND VIBRATED EVEN MORE TOWARD THE FRONT. THE F.A. SAID THE VIBRATION LESSENED IN THE REAR. WITH THE GEAR DOWN AND THE FLAPS AT 25, THE AIRCRAFT LANDED WITH THE RUDDER PEDALS AND CONTROL YOKES SHAKING ALMOST LIKE A STICK SHAKER. THE AIRCRAFT LANDED SAFELY AND TAXIED TO THE GATE. MAINTENANCE INSPECTED THE AIRCRAFT AND NOTICED THAT THE LAVATORY SERVICE DOOR WAS NOT FAIRING PROPERLY. THEY REMOVED THE DOOR AND OPERATED THE AIRCRAFT WITH IN ACCORDANCE WITH THE CDL. ANOTHER DOOR WAS INSTALLED AND THE PROBLEM HAS NOT RETURNED.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
