NTSB Issues Recommendation A-11-071 to FAA Regarding Fuel Additive Limitations

The National Transportation Safety Board, identified by reference number WPR09MA159, has issued safety recommendation A-11-071 addressed to the Federal Aviation Administration. This directive calls for a regulatory change concerning the documentation of fuel system requirements in aviation manuals. Specifically, the NTSB urges the FAA to require that all existing certificated aircraft, encompassing both newly manufactured models and those already in service, display explicit warnings within the limitations section of their airplane flight manuals. These highlighted warnings must specifically identify any necessity for fuel additives, including fuel system icing inhibitors. The goal is to ensure that pilots and maintenance personnel are immediately aware of these critical operational constraints through standardized and prominent notation in the official flight documentation.
