Incident Overview
The flight crew was operating a repositioning flight when they experienced a restriction to aileron control while maneuvering to land. On approach, control of the ailerons was limited to the left and absent to the right. Despite these limitations, the airplane landed successfully.
Investigation Findings
A subsequent examination of the aileron cable disclosed that it was broken. An independent metallurgical examination of the cable revealed that the failure was consistent with the cable having come off the pulley and wearing against a small diameter steel pin.
Fleet Inspection
Following the incident, a complete inspection of the airline's fleet was conducted on the aileron control cables. No similar discrepancies were found.
