## Narrative

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

NARRATIVE: FLIGHT 3266 FROM BAL TO CHO EXPERIENCED A CONTROL DISCONNECT ON FINAL APPROACH TO CHO. IN TURBULENCE THIS IS IDENTICAL TO THE INCIDENT THAT OCCURRED IN PIT ON 02-21-97 (IEA07970023). AIRCRAFT N923HA WAS INVOLVED IN BOTH INCIDENTS. TO CORRECT THE SECOND INCIDENT, PIEDMONT RERIGGED THAT ROLL DISCONNECT SYSTEM. ON 04-01-97 PIEDMONT WAS ASKED TO VOLUNTARILY GROUND AIRCRAFT N923HA AND TO PERFORM ANOTHER INSPECTION AND REPLACE THE CLUTCH SPRING. THEY GROUNDED THE AIRCRAFT AND INSPECTED IT AND REPLACED THE CLUTCH SPRING, TORQUE TUBE BEARING, AND DISCONNECT RETURN SPRING. THE AIRCRAFT WAS THEN RELEASED TO SERVICE. ON 04-09-97 NTSB INVESTIGATOR BOB HANCOCK REQUESTED THAT SEVERAL ADDITIONAL CHECKS BE PERFORMED ON PIEDMONT AIRCRAFT N923HA. SINCE I WAS GOING TO BE IN SBY ON 04-11-97, I ELECTED TO OVERSEE THESE CHECKS. THE RESULT OF THE CHECKS WERE NEGATIVE. I WAS NOT ABLE TO ACHIEVE AN UNCOMMANDED ROLL CONTROL SEPARATION. THIS PROBLEM IS STILL BEING STUDIED BY PIEDMONT, BOMBORDIER AIRCRAFT OF CANADA, AND THE NTSB.

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.
