AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect the function of the pressure relief valves of each spoiler servo control (SSC) and take corrective action if necessary. Revise the Limitations Section of the airplane flight manual (AFM) to ensure flightcrew is advised of proper procedures in the event of uncommanded spoiler movement. Eventually modify the SSCs, which terminates the AFM revision requirement.
