Unsafe Condition
Jamming of the hydraulic fire shut off valve (FSOV) actuator could result in inability to isolate hydraulic fluid from an engine fire.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Perform a one-time operational test within 450 hours time-in-service after the effective date to detect bearing failure of the electric motor and FSOV malfunction. If failed, replace the FSOV prior to further flight. For airplanes with prior single test, perform another test within 900 hours time-in-service. If failed, replace the FSOV prior to further flight. No action required if two or more prior tests were conducted.
