Diesel exhaust fluid (DEF) mistakenly entering the Jet A product stream on airport has become a big thing, so Avfuel has launched a free online training program for FBO personnel to learn the best practices of handling DEF in an airport environment. DEF, when injected into the Jet A supply, can cause blockage of fuel filters and engine shutdowns.
“Our goal is to do whatever we can to help mitigate the risks involved with fueling mishaps, especially in light of the various issues the industry has seen in regard to DEF being mistaken for fuel system icing inhibitor,” said Randy Harrison, Avfuel’s quality assurance supervisor. “Providing a comprehensive resource for all fuel handlers to train with throughout our network—from our truck haulers to flight departments with their own fuel farms and, of course, FBOs—is a step in the right direction to help mitigate this threat to the industry.”
According to the company, “Both the FAA-approved program and the free fuel safety program include training topics to help mitigate fuel incidents, including: the DEF program; an extensive course on the proper usage, labeling, storage and handling of aviation fuels and additives; and additional comprehensive training focused entirely on fuel system icing inhibitor’s proper usage, storage protocols and handling for added safety measures.”
Earlier this year, the industry created a working group to help educate FBO personnel on the risks of mistaking DEF for deicing fluid. In late May, two Cessna Citations had flameouts on the same day as the result of DEF “poisoning.”
Why is DEF even on or near airport fueling facilities?
It’s used in service vehicles, including fuel trucks, at the FBO.
