The FAA has issued a special airworthiness information bulletin (SAIB) warning aircraft owners and operators with auto fuel supplemental type certificates (STC) to ensure the fuel they use does not contain alcohol (ethanol or methanol). The SAIB reinforces EAA’s ongoing efforts to ensure the availability of compliant autogas by heading off or modifying legislative attempts in several states to require ethanol in all gasolines sold.  EAA, one of two primary sources of automobile gasoline STCs for general aviation aircraft, advocates that, at the very least, states should exempt premium grade fuel from ethanol mandates to ensure a readily available and safe fuel supply for aircraft.
