FAA Releases Diesel Exhaust Fluid (DEF) Safety Risk Assessment Report

The Federal Aviation Administration (FAA) released a safety risk assessment report on jet fuel contamination with Diesel Exhaust Fluid (DEF). The assessment was based on the risk matrix and severity and likelihood definitions from the FAA Order 8040.4B, Safety Risk Management Policy. The report was prepared by the Safety Risk Management (SRM) team comprised of NATA staff, FAA representatives, and industry stakeholders. As noted in the memorandum, the SRM team identified a high initial risk associated with this safety issue and the potential to have a high residual risk, due to the common cause factor that the fuel system supplies all engines on the aircraft of failure, if joint efforts with the Environmental Protection Agency (EPA) are unable to remove the hazard. The FAA continues to work with the EPA on potential regulatory mitigations. READ MORE (NATA)
