NTSB Issues Recommendation A-11-073 to FAA Regarding Fuel Additive Placards

The National Transportation Safety Board (NTSB) has issued safety recommendation A-11-073, identified by reference number WPR09MA159, addressed directly to the Federal Aviation Administration. This directive calls for a regulatory requirement that all existing certificated aircraft, encompassing both newly manufactured models and in-service aircraft, must be equipped with a specific fuel filler placard if they require fuel additives, including fuel system icing inhibitors. The mandated placard is intended to clearly note this operational limitation and direct pilots to consult the airplane flight manual for detailed information regarding the restriction. This measure aims to ensure that operators are explicitly aware of the need for these specific fuel treatments during pre-flight checks.
