The FAA’s recent special airworthiness information bulletin (SAIB: NE-09-25R1) regarding recommended safe-operating guidelines in the possible presence of the jet-fuel contaminant Fame (fatty acid methyl ester) has caused some confusion among operators. The agency is concerned that jet fuel could be exposed to Fame contamination through the use of multi-product fuel-transport systems and is taking steps to begin educating operators.

The Renewable Fuel Security Act will mandate–starting next year–a significant increase in the amount of biodiesel that petroleum manufacturers need to produce, said Mark Rumizen of the FAA’s Engine and Propeller Directorate. To accommodate that significant increase in volume, they are going to have to start shipping it through the pipelines, at which time “[Fame contamination] will be a very real concern,” he added.
