AI-generated summary of the official EASA document. Verify against the PDF before acting.
What to do
Operators and maintenance personnel should regularly inspect all fuel drain locations using clear sampler cups before every flight, ensure fuel drain valves and raised umbrella-style fuel filler caps are installed and in good condition, and take precautions to prevent water ingress from external sources. During scheduled inspections, check fuel system components for corrosion or damage and ensure fuel quality by verifying supplier controls. Contaminated fuel must be fully drained and the system purged by qualified personnel before further flight. No specific compliance deadline is stated.
Summary
The Special Airworthiness Information Bulletin SAIB CE-10-40R1 addresses water contamination issues in the fuel tank systems of Cessna single-engine airplanes, including models from the 100, 200, and 300 series manufactured by Cessna Aircraft Company and formerly Reims Aviation S.A. This bulletin informs pilots, owners, operators, and maintenance personnel about the hazards of water in fuel systems and provides guidance on inspection and prevention. It is an informational document and does not mandate regulatory action.
What changed
SAIB CE-10-40R1 revises the earlier SAIB CE-10-40 dated July 27, 2010, by adding more Cessna models potentially affected by water contamination in fuel tank systems. The revision incorporates feedback from organizations and other airworthiness authorities to expand the scope of the advisory. The FAA has determined that this issue does not currently warrant an airworthiness directive under 14 CFR Part 39.
Why it matters
Water contamination in fuel systems can lead to engine failure and unsafe flight conditions, making it critical for aviation professionals to understand and mitigate these risks. Operators and maintenance teams must be vigilant in inspecting fuel drains and caps to prevent water ingress and contamination. Proper fuel system management enhances flight safety and reduces the risk of accidents related to fuel quality issues.
