Incident at Hartford, Connecticut, USA


1996-01-19: Aircraft was on approach to Hartford and was encountering severe wind and turbulence. The crew heard a "thud" and recognized the noise as a roll control clutch disconnect. The captain was flying and maintained control, while the first officer returned his control wheel to neutral. The flight continued and landed without further incident. Upon landing, the roll control disconnect clutch re-engaged. A maintenance crew could not determine any fault with the system, even after a rigging check of the flight control system was carried out. The manufacturer was notified of the occurrence and it appears that two other identical incidents were reported to the manufacturer. The manufacturer had started to modify the roll disconnect system and was in the process of implementing an In-Service Activity Report (ISAR) followed by a Service Bulletin to other operators of this model. It appears the commonalities between the occurrences are the model of aircraft and years in service. ISAR 96-02-2710 will be issued immediately, to be followed shortly after by a SB. From a TSB Initial Notification.
