Analysis
An uncommanded deployment of the #8 leading edge slat occurred during a climb. Control of the acft was not affected & the flt continued to the destination. The crew attempt to recycle the slats, but to no avail. An exam of the #8 slat actuator did not disclose a malfunction or failure. However, Boeing did report the actuator retract lock switch displayed evidence of an intermittent malfunction that could have falsely indicated that the actuator was retracted, when in reality it had not.
