Incident

May 9, 2019 · Savannah, GA

The lineman's inadvertent introduction of diesel exhaust fluid (DEF) to the fuel truck fuel system icing inhibitor reservoir, which resulted in fuel contamination and a total loss of engine power. Contributing to the accident was the fixed-base operator's failure to ensure that DEF was stored off-airfield in accordance with their own policy.
