What to do
Operators and maintenance personnel should follow the recommendations from the FAA and JIG as endorsed by EASA, ensuring FSII additives are correctly identified, dosed, and handled during refueling and maintenance. No mandatory actions or compliance deadlines are specified, but vigilance and adherence to flight manual instructions are strongly advised to mitigate risks.
Summary
EASA Safety Information Bulletin 2019-14R2 is an airworthiness bulletin addressing the use of fuel system ice inhibitor (FSII) additives in all aircraft that require or allow FSII for safe operation. It highlights risks associated with improper FSII usage, including incidents where Diesel Exhaust Fluid was mistakenly injected instead of FSII. The bulletin references FAA and Joint Inspection Group publications to raise awareness and promote safe FSII handling practices.
What changed
EASA SIB 2019-14R2 revises the previous version 2019-14R1 by updating the applicability and referencing newly published FAA Safety Alert for Operators SAFO 18015 and FAA National Part 139 Cert Alert 23-04. It also updates the references to related FAA and JIG advisory documents to reflect the latest safety information.
Why it matters
This bulletin is important for aviation professionals because improper FSII use can compromise fuel system safety and aircraft airworthiness. Operators, maintenance organizations, and compliance teams need to be aware of the risks of FSII contamination or incorrect dosing to prevent fuel system malfunctions and ensure adherence to flight manual limitations and placard instructions.
