NTSB Issues Safety Recommendation A-11-074 to FAA on Fuel System Icing Prevention

The National Transportation Safety Board, identified by reference number WPR09MA159 and safety recommendation A-11-074, has issued a directive to the Federal Aviation Administration. This safety recommendation calls for the issuance of specific guidance concerning fuel system icing prevention. The requested guidance must address two primary areas. First, it should include pilot precautions and procedures designed to help operators avoid fuel system icing problems aboard turbine engine-powered aircraft. Second, the guidance must describe the possible consequences of failing to use a fuel system icing inhibitor when such use is required by the airplane flight manual. This requirement is particularly emphasized for operations conducted at high altitudes and in cold temperatures.
