SAIB: CE-11-08 Actual fuel quantity in the aircraft

This Special Airworthiness Information Bulletin (SAIB) alerts you, owners, or operators of Cessna Aircraft Company Models 206 and 207 Aircraft that have installed auxiliary fuel tank bladders in accordance with Sierra Industries, Ltd. Supplemental Type Certificates (STC) SA3634SW or SA3853SW, of a potential airworthiness concern where operators may not be aware of the actual fuel quantity in the aircraft. This may be caused by not allowing enough time to let the fuel to settle through the bladders following the refueling process.

At this time, the Federal Aviation Administration (FAA) has determined that this airworthiness concern is not an unsafe condition that would warrant airworthiness directive action under Title 14 of the Code of Federal Regulations (14 CFR) part 39.
