This Revised Special Airworthiness Information Bulletin (SAIB) clarifies the recommendation regarding the dispositioning of jet fuel contaminated with Diesel Exhaust Fluid (DEF). The SAIB advises airplane operators, fixed base operators (FBOs), FAA repair stations, Flight Standard District Offices (FSDOs), and foreign civil aviation authorities of certain airplanes that uplifted jet fuel contaminated with DEF, or uplifted jet fuel using refueling equipment that was exposed to DEF. This SAIB also requests feedback regarding any service difficulties or operational anomalies of the identified airplanes and recommends that the owners of those airplanes consult with the original equipment manufacturers (OEMs) of their airplane, engine, and auxiliary power unit (APU) to determine the appropriate inspection and corrective maintenance actions on their airplane. This revision corrects and clarifies the Recommendations paragraph.
