Required Actions

Remove certain life raft reservoirs from service, inspect the reservoirs and actuator cables, and depending on the inspection results, replace the reservoir or adjust the actuator cable. Inspect the valve pull rod by measuring the actuator cable between the face of the pull rod and the back of the valve cap, inspect the actuator cable by verifying the presence of a clearance between the sphere at the end of the actuator cable and the activation system, and adjust the actuator cable.
