Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident
The Captain reported they were flying a visual approach following the localizer to intercept the glideslope. When flaps 45 were selected, the airplane rolled right about 15 to 20 degrees. Application of left aileron and rudder controlled the roll, and the approach was aborted. After consulting maintenance and flight operations and conducting a visual inspection, the Captain determined they had a failure of the right flight spoiler. A decision was made to land using corrected speeds per the checklist. The approach and landing were uneventful. A post-flight inspection revealed the right flight spoiler was fully deployed and the right spoiler lug had fractured and separated from the hydraulic actuator. A review of the maintenance records indicated the right flight spoiler had acquired a total of 3,987.9 cycles and 4,064 landings. Metallurgical examination revealed the aluminum spoiler lug had failed due to fatigue. Transport Canada issued an Airworthiness Directive on February 22, 2001, that required the inspection of aluminum flight spoiler lugs at 3,000 cycles, and at intervals not to exceed 500 cycles. The AD also stipulated that the installation of redesigned flight spoilers which utilized steel lugs provided terminating action to the inspection requirements. The FAA issued an AD on July 26, 2001, that required the same inspection criteria as the Transport Canada AD.
NTSB Probable Cause Narrative
The uncommanded deployment of the right flight spoiler due to the fatigue fracture of the spoiler lug.
