FAA Advises GA Pilots to Check for Fuel Contamination
November 15, 2011 – With winter beckoning, the FAA has issued a Special Airworthiness Information Bulletin (SAIB) stressing the hazards of water contamination of fuel tank systems to GA pilots, owners, operators, and maintenance and service personnel. The fuel tank system consists of all tanks, components, lines, fittings, etc. – from the fuel tank to the engine.
“Water may enter the fuel tank system via any penetration in the wing fuel tank and from moisture condensation inside the tank,” warns SAIB CE-12-06, dated November 2, 2011. “Water in the fuel may come out of solution, settle, and make its way to a drain location in the form of a blob, pea, or BB-shaped translucent mass found at the bottom of the sampler cup.”
A full slate of recommendations is included in the SAIB. Download a copy here.
