Unsafe Condition
Flight in freezing rain, freezing drizzle, or mixed icing conditions may result in ice build-up on protected surfaces exceeding the capability of the ice protection system, or may result in ice forming aft of the protected surfaces, which may not be shed using the ice protection systems and may seriously degrade the performance and controllability of the airplane.

Required Actions
Revise the FAA-approved Airplane Flight Manual (AFM) by incorporating specified warnings and procedures into the Limitations and Normal Procedures Sections, including visual cues for severe icing conditions, prohibitions on autopilot use, and requirements for wing icing inspection lights. Ensure flight crewmembers are apprised of these changes.
